SHITCREW fucks your burn 🍄

Festival composting toilets that feed a worm farm. One month of loos, twelve months of happy worms, built from plywood and Mitre 10 bits.

🌈 How it all works

🚽 Toilet cubicleA flat-pack plywood cubicle with a urine-diverting seat. Wee and poo are kept apart.
→
🪣 50 L steel bucketSolids plus a scoop of sawdust after each use. Swap the bucket when it is about ⅔ full (~25–30 kg).
→
⏳ Holding bayBuckets are emptied into a covered, lined bay where the material rests for 6–8 weeks. Ammonia gases off and it starts to break down.
→
🪱 Worm bedsFed in thin layers (5–8 cm) every 2–4 weeks across the warm months. Tiger worms turn it into vermicast.
→
🌳 Cure & useHarvested cast cures for 6 more months. Use it on trees and ornamentals, never on raw salad crops.

Urine goes separately to a container. Dilute it 1:10 and spread it on pasture or shelter trees, or run it to a soakage trench, subject to council rules.

Why the holding bay matters

Fresh humanure tipped straight onto worms in a thick layer heats itself up and releases ammonia. That kills the worms. Your input is one big month, followed by eleven quiet months. The holding bay soaks up the surge so the worms can be fed at a pace they can handle. The rest of the year they live on manure, cardboard and food scraps.

Why divert urine

Most of the smell, weight and ammonia comes from urine. Urine also contains salts that worms can't tolerate. Diverting it makes each bucket about 3× slower to fill, much lighter, nearly odourless, and safe to feed to worms.

Hunterville climate in short

Warm summers (maxima low–mid 20s °C, occasional 28–30 °C days). Cold, frosty winters (minima around 0–3 °C, frequent frosts June–August). Roughly 900–1100 mm of rain a year. Worms work best at 15–25 °C, slow right down below 10 °C, and die above about 30 °C or when frozen. Beds need shade, insulated lids and rain protection. (Approximate figures. Check NIWA CliFlo for your exact site.)

  • Planner: enter the number of people and days. It works out toilets, buckets, sawdust, holding bays, worm bed area, worms to buy and a month-by-month feeding plan.
  • Toilet cubicle: a plywood festival cubicle built from 4½ sheets with almost no waste. It flat-packs for the 11-month off-season, has a choice of cut-out motif and colour, and includes a cost estimate.
  • Accessible cubicle: a 2.4 × 2.4 m wheelchair-accessible version of the same flat-pack box, laid out to NZS 4121. It has grab rails, a 1500 mm turning circle, a sliding door and a ramp calculator, plus an ambulant upgrade for crutch users.
  • Bucket wash station: a keg-washer-style rig. The bucket goes mouth-down over a spinning nozzle driven by the Kärcher, with a foot pedal, and all the waste drains to an IBC for the sucker truck.
  • Worm farm: lined timber bays with insulated lids, a leachate tap, drawings and a cut list.
  • Kitchen sand trap: the camp kitchen sink drains through a blue barrel of sand strapped to a tree, so only clean water reaches the paddock. Includes a drawing, a sizing tool and where to buy everything near Hunterville and Palmy.

Monthly worm feeding plan

Feeding is weighted by how warm each month is in Hunterville, so worms get more in summer and very little in winter. The month before the next festival is kept free to harvest and make room.

These are planning estimates, not lab values. Assumptions: settled poo + paper ≈ 0.3 L per use. Diverted-mix density ≈ 0.7 kg/L (0.85 undiverted). Undiverted adds ≈ 1.2 L urine + 1 L extra sawdust per person-day. The holding bay loses ~30% of mass. Outdoor tiger worm beds process roughly 4–8 kg/m²/week at 15–25 °C. Watch the first year and adjust the numbers.

🚽 Plywood festival cubicle

Pick a character

Every cubicle is the same cheap flat-pack box. The character is just one extra ply sheet (a false front) cut to shape and screwed onto the front wall. You can mix a whole village and swap the fronts each year.

Vent cut-outs go on the sides, and on the front of the classic & chalet designs.

Design principles (cheap + good-looking)

  • 1.2 × 1.2 m footprint, sized to whole sheets. Each wall is one 2400 × 1200 sheet, so there are almost no cuts or offcuts.
  • Flat-pack panels. Each wall is a sheet glued and screwed to a 90 × 45 frame: studs at each edge and one in the middle (600 centres), with dwangs (nogs) at 600, 1200 and 1800 mm so no piece of ply spans more than 600 mm. Panels bolt together at the corners with M10 coach bolts. It packs flat into a ute and stores dry for the other 11 months. Two people can put one up in about 20 minutes.
  • Skillion roof of clear or opal polycarbonate (e.g. Suntuf). It gives daylight inside, is cheap and light, and the fall to the back keeps rain off the door.
  • Tractor-towable skids: two 150 × 100 H5 skids, 1.8 m long, with chamfered ends so they slide like a sledge either way. A galvanised tow eye is through-bolted at each end. No digging, it sits level on paddocks, and a tractor can drag it into place, or lift it on pallet forks through the gap between the skids.
  • Bucket access from the back. A hatch in the back wall lets crew swap buckets without going inside. It's quicker, more hygienic and keeps the queue moving.
  • Character fronts: the fun lives on one extra 12 mm sheet cut into a mushroom cap, rocket nose, castle battlements or chalet gable, screwed onto the front wall. It costs about $100–130 extra per cubicle, and the box underneath never changes.
  • Kiwiburn fronts: the DoBro can is a nod to Double Brown ("DoBro"), the cheap DB bitter every Kiwi paddock party knows. Paint the band gold with a red pinstripe, and cut the ring-pull from an offcut so it sits above the roofline. Moss & Microchips follows the Kiwiburn 2027 theme: green ply "moss" blobs drip over the roof, and the cut-outs are circuit traces routed as 12 mm slots, backed with opal polycarbonate so they glow at night. Hand-paint the lettering yourself rather than copying the real DB logo.
  • Moss & Microchips versions (M&M): every original character also comes in a Kiwiburn 2027 version: Mossy Mainframe, Glowshroom, Moss Rocket, Circuit Citadel, Faerie Chalet, Motherboard Gingerbread and Pixel Beach Hut. They keep the same shape, but get deep moss-green walls, ply moss blobs dripping off the eaves and up from the ground, routed circuit traces backed with opal polycarbonate or a solar LED strip, and a row of little "status lights".
  • Kitchen fronts: the Soup-er Bowl is a giant bowl of tomato soup across the lower front, with veg "croutons", a ladle poking above the roof, and steam swirls cut out above the bowl. The Potty Pot is an enamel stock pot, with a domed lid sitting on the roof, loop handles made from bent poly pipe, and glowing bubble cut-outs. Both are good next to the camp kitchen.
  • Glow at night: back the cut-outs (spots, portholes, hearts) with offcuts of opal polycarbonate. They look white by day, and with a solar light inside they glow like lanterns after dark. Add a string of solar fairy lights along the roofline.
  • Bright paint, oiled inside: a bold colour and pattern outside (exterior acrylic sample pots are cheap for the dots and stripes), and natural oiled ply inside so it's light and wipeable.

Sheet layout (one cubicle)

Side walls are raked (2400 at the front → 2100 at the back). Each raked offcut becomes a roof gusset. The floor sheet's spare half makes the pedestal box.

Materials & rough cost

Prices are rough NZD guesses for 2026 hardware-shop retail, so confirm them in store. Trade accounts, second-hand ply and buying sheets in bulk can cut this by 20–40%.

Build steps

  1. Base: two 1800 mm H5 150 × 100 skids laid on edge, 900 mm apart (centre to centre), with the bottom of each end cut back at 45° over 150 mm like a sledge runner. Fix four 90 × 45 H3.2 joists across at 400 centres, each skewed and nailed plus a 12 mm galvanised bolt through every joist into the skid, because towing loads it far harder than standing does. Screw the 17 mm ply floor on top and seal its edges with paint.
  2. Tow points: through-bolt an M16 galvanised eye bolt (or a 10 mm shackle on a bolted steel plate) through each skid end, 50 mm up from the bottom, so you can hook on a two-leg chain bridle from either end.
  3. Wall frames: each wall gets 90 × 45 studs at both edges and one in the middle (600 centres), a bottom plate, and a top plate (raked on the side walls). Add dwangs (nogs) between the studs at 600, 1200 and 1800 mm. Stagger them up and down by 45 mm so you can end-nail each one. See "Wall framing" below for the extras. Glue and screw the 12 mm ply on every 150 mm around the edges and every 300 mm on the middle stud and dwangs. Paint all edges before assembly, because end grain is where ply fails.
  4. Extra dwangs go behind everything that's screwed to a wall: the door hinges and latch, the toilet roll holder (~700 mm), the coat hook (~1600 mm), the rules sign, the solar light, and the sawdust shelf. Add one 400 mm below the top to frame the bottom of the motif band, and keep cut-outs clear of the middle stud.
  5. Side walls: rake the top from 2400 (front) to 2100 (back). The cut line is a straight chalk line.
  6. Cut-out band: mark the motif 150–350 mm below the top on the front and side walls. Drill a 10 mm start hole and jigsaw it out. Staple fly mesh behind every opening (essential, because flies are the main way disease spreads).
  7. Front wall: rip the sheet into a 700 mm door and a 500 mm fixed panel. Frame the door, hang it on 3 tee hinges, and fit a self-closing spring hinge or bungee, a pull handle and an inside barrel bolt. An outside "vacant/engaged" slider is a nice touch.
  8. Back wall: cut a 550 × 600 hatch at the bottom, behind the pedestal, and hang it on hinges with a padlock hasp. Crew-only.
  9. Assemble: stand the walls, clamp, drill and bolt the corners with 4 × M10 × 120 coach bolts per corner. Bolt each wall's bottom plate down through the floor into the joists with M10 bolts at 400 centres, not screws, so the box can't rack or lift off when it's towed.
  10. Roof: fit two 90 × 45 purlins on the raked tops and fix the polycarbonate with the proper roofing screws and washers. Overhang 150 mm at the back and sides, and 300 mm at the front over the door.
  11. Pedestal: build the 17 mm ply box (see section), fit the urine diverter and seat, and run the 25 mm urine hose out the back wall to the container. Fit a 100 mm PVC vent from the top of the box up past the roof by 300 mm, with fly mesh + cowl.
  12. Fit-out: sawdust bin + scoop, a toilet roll holder, a hook, a mirror, a small sign with the 3 rules, and a solar light. Put a hand-wash station outside (see below).
  13. Finish: exterior acrylic outside (2 coats), and decking oil or clear water-based poly inside so walls can be wiped down.
  14. Character front: draw a 100 mm grid on the extra sheet and copy the shape from the drawing above. Jigsaw it out, sand the edges, seal and paint them. Screw it to the front wall frame every 300 mm, with a 90 × 45 brace behind anything that sticks up more than 600 mm (rocket nose, flag). Rocket fins screw to the side-wall corners. Tall fronts catch wind, so stake every cubicle.
  15. Patterns: mask the stripes with tape. Do polka dots with a sponge roller cut into a circle, or a tin lid as a stencil. Do confetti freehand with sample pots (a great volunteer job).

Wall framing (dwangs / nogs)

The inside face of each wall, with studs at 600 centres and dwangs at 600, 1200 and 1800. The orange dwangs are the extras that carry fittings. The door leaf gets a Z-brace so it doesn't sag.

🚜 Moving by tractor

  • Empty it first: take the bucket out, cap the urine container, unhook the vent cowl if it's tall, and latch the door and hatch shut. Nobody rides inside.
  • Two-leg chain bridle from both tow eyes at one end to a ring on the drawbar. Keep the legs roughly equal, so it pulls straight and doesn't twist the box.
  • Walking pace, straight lines, wide turns. Have a spotter walk beside it. Stop for ruts and hump the skids over them slowly.
  • Or lift it: pallet forks go between and under the skids (the 150 mm depth gives fork clearance), with a strap over the roof to the loader.
  • Tall fronts (rocket, castle flag, DoBro ring-pull) catch branches and wind. Unbolt the flag and keep the speed down.
  • Afterwards, check that the corner bolts, floor bolts and roof screws are tight and that the door still closes square.

Toilet rules sign (inside)

  1. Sit down, everyone (even for a wee). It keeps the wee in the front bowl.
  2. After a poo: 1 scoop of sawdust to cover it completely.
  3. Paper is fine. Nothing else: no wipes, pads, tampons, nappies, rubbish, cleaning sprays or water.
  4. Lid down, door shut, wash your hands.

Cheap fun extras

  • A chalkboard-paint panel inside the door, with chalk on a string, as a guestbook or graffiti wall.
  • An engaged/vacant spinner: a ply disc on a bolt with 😊 / 😬 faces.
  • Label the sawdust bin "Magic Dust" or "Poo Glitter". People use it more.
  • A mirror with "you look great today" painted above it.
  • A tiny shelf with a succulent or a jar of festival flowers.
  • A "Poo-etry" corner: a laminated sheet of jokes or short poems, changed daily.
  • A sign about the worm farm: "Your donation feeds 10,000 worms 🪱". People love knowing where it goes.
  • Name every cubicle (🎲 above) so people can say "meet at the rocket".

Hand-wash station

A 20 L water container with a tap (or a foot-pump), a timber stand, a soap pump and a 20 L grey-water bucket underneath, emptied onto a gravel soak pit away from the beds. Allow about 1 station per 2 cubicles. Refill it every day and check the soap twice a day. Hand washing is the single most important health control on site.

♿ Accessible cubicle

This is a bigger version of the same flat-pack plywood box. It is built for wheelchair users and works well for people on crutches, walking frames, or with a carer. It is 2.4 × 2.4 m outside, which is two whole ply sheets per wall again, so there are still almost no offcuts. Inside there is about 2.19 × 2.19 m of clear floor. That is well over the NZS 4121 minimum compartment (1900 × 1600 mm) and leaves room for a 1500 mm turning circle, so a wheelchair can turn round in one go.

The dimensions follow NZS 4121:2001 Design for access and mobility as summarised by Taupō District Council and the Auckland Design Manual. Buy or borrow the Standard to confirm them, and above all get a wheelchair user and a crutch user to try it before the event.

Plan (from above)

The pan sits in one corner with the grab rail wall beside it. The door slides open onto the big clear side, so a wheelchair rolls straight into the transfer space.

Rail wall (elevation)

This is the left wall, seen from inside. The rails need solid timber behind them, because ply alone will tear out.

🧮 Ramp & path

The cubicle floor sits up on skids, so it needs a ramp. NZS 4121 allows 1:12 at most. On a festival paddock, aim for 1:14 or gentler, because grass and mud make every slope harder.

  • Ramp: 1200 mm wide between handrails, made of 17 mm ply on 90 × 45 bearers with anti-slip paint. Fit 75 mm kerb rails along both edges so wheels can't drop off.
  • Handrails both sides at 900–1000 mm high, running 300 mm past the bottom of the ramp. You can skip them if the ramp is 1:20 or gentler.
  • Landings: a level 1500 × 1500 mm landing at the door (the sliding door means no swing to dodge) and a level, firm pad at the bottom.
  • Adjustable for the paddock: build the ramp as 1.2 m long modules, each a ply deck on two 90 × 45 bearers with an adjustable foot at every corner. Modules bolt together end to end, and the top one hooks onto the landing with heavy strap hinges, so the whole run can follow the ground without a step at any join.
  • The feet: an M16 galvanised threaded rod (300 mm) through a steel angle bracket bolted to the bearer, with a nut and washer above and below. It stands on a 300 × 300 paver or 17 mm ply pad, with a waratah or peg beside it so it can't walk. A spanner gives 0–250 mm of adjustment per corner. Bolt-down adjustable deck pedestals or screw jacks from the decking aisle work too.
  • Level it in this order: first get the cubicle level both ways using packers or feet under the skids. Then set the landing level with the door threshold. Finally run a string line from the landing edge to the bottom at your chosen slope (the calculator gives the length) and wind each foot until its module touches the string. Keep side-to-side cross-fall under 1:40 and any lip at a join under 5 mm.
  • After rain, check it again. Paddock ground softens and pads sink, so re-check level and the joins every morning, and after heavy rain.
  • Lowest-effort option: dig the skids into the ground so the floor sits about 50 mm up, then a short wedge ramp is all you need.
  • The path matters as much as the loo. A wheelchair can't cross a wet Hunterville paddock. Lay a firm path 1.2 m wide from the nearest main track, using ply panels on bearers, rubber ground mats or hired trackway. Kiwiburn's own accessible portaloos are by the medics and in the middle of the lower paddock, so put this one near a main track too.

Inside the cubicle

  • Pedestal box: the same bucket box as the standard loo, built so the seat top is 460 mm above the floor (with a 50 L bucket, make the box taller or sit the bucket in a recess). Put the front edge of the seat 700–750 mm from the back wall and the centreline 450 mm from the rail wall. Fit a lid and a backrest (a padded board on the box or the back wall), since there's no cistern to lean on.
  • L-shaped grab rail on the side wall: the horizontal part at 700 mm, the vertical part 150–250 mm in front of the seat, up to about 1500 mm.
  • Optional fold-down rail on the open side of the pan, fixed to the back wall. It helps people who push up with both arms, and folds out of the way for side transfers.
  • Transfer space: keep at least 850 mm beside the pan completely clear: no bins, no sawdust bucket, no shelves on the floor.
  • Within reach of the seat: toilet paper on the rail wall at about 700 mm, a little in front of the seat. Put the sawdust bin on a 750 mm shelf on the back wall on the open side, with a long-handled scoop. Put sanitiser and a sanitary bin on the rail wall.
  • Door: a sliding "barn" door on an outside track, light enough to move with one finger. Fit a long horizontal pull rail on the inside at 900 mm, D-pulls outside, and a lever or large-knob lock you can work with a closed fist. Mark it with a clear engaged/vacant indicator.
  • Help cord: a red cord hanging to 100 mm above the floor and running to a loud bell or buzzer outside, with a sign saying who responds (the nearest camp or the medics).
  • Hooks at 1200 mm and 1600 mm, a mirror from 900 mm up, a motion-sensing solar light, and contrasting colours on the rails, seat and door edge for low-vision users.
  • Floor: anti-slip paint, no step at the door (threshold under 10 mm), and a drop of grit in the paint.
  • The bucket hatch stays in the back wall, so crew never need to go inside.
  • Frame and base: the walls are framed like the standard cubicle (studs at 600, dwangs at 600/1200/1800) plus the rail dwangs. It sits on three 150 × 100 H5 skids, 3.0 m long, with chamfered ends and tow eyes at both ends, so a tractor can move it like the others. Unhook the ramp modules and the landing first, because they lift off their hinges.

🩼 Ambulant upgrade (crutches, walking frames)

Lots of people who use crutches or a stick don't need a wheelchair-size loo, but they do need something to hold on to. Convert about 1 in 4 of the standard cubicles:

  • Horizontal grab rails on both side walls at about 800 mm, running from 200 mm behind the seat front to 400 mm in front of it, with solid timber behind them.
  • Seat height 460–480 mm, with a backrest.
  • The door opens outward (so it can't trap someone who falls) and has a pull rail on the inside.
  • Fit a short ramp or one low, wide step (under 150 mm) with a rail, rather than a high step-up.
  • Give them a different door sign, e.g. "🩼 rails inside", so people can find them.

Rails that won't let anyone down

  • Grab rails must carry 1.1 kN (about 110 kg) in any direction. Use 32–38 mm stainless or galvanised tube, set 50 mm off the wall.
  • Behind every rail, add 90 × 45 dwangs (horizontal blocking) at rail height inside the wall frame, and through-bolt the rail flanges with M8 bolts and large washers. Don't use screws into 12 mm ply alone.
  • Test each rail by hanging your full weight off it before the event, and again every morning.

🛒 Extra materials & where to get them

This is on top of a standard cubicle's hardware (seat, diverter, vent, solar light and so on: see the Toilet cubicle tab). Prices are rough NZD guesses, so confirm them in store. The stores are listed on the Kitchen sand trap tab.

How many?

Plan on at least one accessible cubicle per toilet bank (more if you know participants who need them), placed at the end nearest the track, plus the ambulant upgrade on about a quarter of the standard cubicles. Tell the Kiwiburn organisers where it is so they can add it to the map and let participants who asked about access know.

🚿 Bucket wash station

🪣 EmptyTip the bucket into the holding bay as usual, then wheel it to the station on the trolley.
→
🔄 Flip & dropPut it mouth-down on the grid inside the splash drum, then close the lid. Like a keg washer, your hands never go in the bucket.
→
💦 BlastPush the pedal. The Kärcher drives a 360° spinning nozzle pointing up into the bucket. 30–40 s cleans the inside, and a second short burst does the rim.
→
⬇️ DrainEverything runs by gravity down a 100 mm pipe into a 1000 L IBC. Nothing goes on the ground.
→
🚛 Suck outThe IBC's bottom valve has a camlock fitting, so the waste truck's hose clicks straight on.

How it fits together

The heights are roughly to scale and the lengths are shortened. Everything flows downhill, from the clean water tank to the Kärcher to the drum to the waste IBC.

🧮 Size it

The waste volume adds about 10% for the residue washed off each bucket. Book the truck when the IBC is about 80% full, not 100%.

The washer drum (keg-washer style)

  • Splash drum: a 200 L blue drum cut down to about 650 mm high. The bucket (Ø 400, 450 high) drops inside with room to spare. Fit a hinged ply lid with a rubber seal and a handle, and close it before every blast so no spray or aerosol escapes.
  • Bucket grid: a stainless BBQ grill or 25 mm galvanised mesh on three bolts, 150 mm above the drum floor, with a ring of offcut timber to centre the bucket over the nozzle.
  • Spray head: a 360° rotating tank-cleaning nozzle (the kind used for kegs and drums) on a short rigid extension lance. It comes up through a sealed bulkhead in the drum floor, sitting about 100 mm inside the bucket mouth.
  • Drain: a 100 mm DWV outlet at the lowest point of the drum floor, with the floor packed to fall towards it. Use no strainer: you want the solids to keep moving to the IBC.
  • Stand: 90 × 45 H3.2 frame with the drum top at about 1000 mm, so the bucket lifts in at waist height. A plywood slab around the top catches drips.
  • Hands-off control: keep the Kärcher trigger gun zip-tied open (the lance is fixed). Fit a high-pressure ball valve (rated ≥ 200 bar) in the line, with a ply foot pedal on a hinge that pushes its lever. Closing the valve makes a Kärcher's total-stop system stop the pump, just like letting go of the trigger. Check that your model has total-stop before relying on it.

Plumbing the Kärcher

  • Water in (running water): run a garden hose from the tap to the Kärcher's inlet, with a dual-check backflow valve at the tap so wash water can never siphon back into the supply, and an inline filter. Turn the tap fully on: the Kärcher needs a steady flow. No running water there? Feed it from a clean-water IBC raised on a pallet instead. Kärcher K-series machines can draw from a tank using their suction hose kit with filter. The tank being higher helps the pump prime.
  • High pressure out: Kärcher gun → (zip-tied open) → Kärcher-to-M22 or ¼" quick-connect adaptor → high-pressure ball valve on the pedal → short extension → rotating nozzle. Buy the adaptor to match your model's gun connector (K-series guns use Kärcher's own click fitting).
  • Power: run it through an RCD, and put the machine on a shelf under a little roof, away from the drum and above any splash. Keep the lead off the wet ground.
  • Hot water helps but isn't needed. A squirt of biodegradable cleaner in the bucket before it goes in loosens stuck sawdust.

The waste IBC

  • A 1000 L IBC (ex-food or water only, never chemicals) on a level, firm base. Its top inlet must sit below the drum drain, with at least a 1:20 fall on the 100 mm pipe. The drum drains at about 350 mm and an IBC stands about 1160 mm tall, so on flat ground it won't drain. Choose one: (1) put the station at the top of a bank so the IBC sits about 1 m lower (best: the bottom valve stays easy to reach); (2) sit the IBC in a pit about 1 m deep (ask the farm, and backfill afterwards: Leave No Trace); or (3) use a smaller, low tank. The calculator checks the height.
  • If the IBC sits in a pit, the truck can just suck out through the lid with its wand, so the bottom valve isn't needed.
  • Optional pump (last resort). ⚠️ Wood shavings and sawdust will block most pumps and small hoses, so only use this if none of the no-pump plans fit. If you do, pick a cutter/grinder (macerator) sewage pump, keep a coarse basket screen you can lift out and empty, and keep a spare pump on site. Flat ground? Use a catchment tub and pump. This is the easiest option when there's no slope. The drum drains a short way into a low catchment tub (a 90 L mortar tub or a cut-down drum about 250–300 mm tall) sitting on the ground under the drum outlet. A submersible dirty-water pump with a float switch sits in the tub: it switches on when the tub fills and lifts the waste up a hose into the IBC lid, which can sit on the same ground. There's no handling and no lifting.
  • Pump choice: it must be a dirty-water or effluent pump rated for solids of at least 25–35 mm (vortex impeller), never a clear-water pump. Fit a non-return valve on the outlet so the hose doesn't drain back. Use 40–50 mm hose, keep the run short, and clip the outlet into the IBC lid so it can't jump out. Power it from the same RCD as the Kärcher.
  • Put a lid with a hole for the pipe and hose on the tub, check the float isn't snagged each morning, and keep a high-level mark on the IBC, because the pump will happily keep filling a full IBC.
  • Inlet: a 100 mm hole cut in the top lid with a tank fitting. Add a vent pipe with fly mesh, and screw the lid tight (flies and smell).
  • Outlet: the IBC's 2" (DN50) bottom valve → a 2" camlock (type A or F) → a camlock reducer to the truck's size. Ask your pump-out contractor what size they use, usually 3" or 4" camlock, and keep the matching dust cap on.
  • Put it within the truck's hose reach of a track the truck can drive on in the wet. Ask them the hose length (often 20–30 m).
  • Mark a fill scale on the side every 100 L with a paint pen, and check it every morning.

Plan 5: tip & rinse straight into the IBC (the simplest)

This plan skips the holding bay for the wash station altogether. The bucket goes in a lever tipping cradle on the IBC, gets tipped upside down over a wide funnel in the IBC's top opening (so the poo, sawdust and all fall straight in), and is rinsed while it's still upside down, with a nozzle pointing up out of the funnel. Nobody touches the inside of a bucket, and you need no pump, no pipes, no slope and no platform.

  • The cradle: a steel ring that clamps the bucket, on two flat-bar arms pivoting on a bolt through the IBC's top frame. Load it at waist height beside the IBC, pull the lever, and the bucket swings up and over, mouth-down onto the funnel's rubber skirt. Any local engineering shop can weld one from flat bar in an afternoon.
  • The funnel: 300–400 mm wide, sitting in the 150 mm top opening, with a rubber skirt so splashes stay in. The rotating nozzle comes up through the middle of it.
  • ⚠️ The trade-off: everything in the bucket goes to the sucker truck, not to the worm farm. The IBC fills much faster (about 30 L per bucket, see the calculator), so you'll book more pump-outs. It's ideal if the compost side is too much work this year, or for overflow on the busiest days.
  • As with every plan: keep the cradle closed while you blast, and wear a face shield and gloves.

Plan 4: wash over the holding bay (no IBC, no pump, no truck)

The buckets are emptied into the holding bay anyway, so you can wash them right there. Set a hatch in the holding bay's lid with a bucket grid and a hinged splash hood (a cut-down drum). The rotating nozzle comes in through the bay wall and points up into the bucket. Rinse water and residue drop straight onto the sawdust and straw in the bay, so there's no IBC, no truck and no pump.

  • The bay's lid is about 1 m high, so the bucket sits at a comfortable height with no platform.
  • Rinse water makes the bay wetter, so add extra sawdust or straw after each wash session (the calculator gives an amount) and make sure the bay's liner and leachate tap are working.
  • Keep the hood shut while blasting, because the bay is full of fresh material.

Plan 2: wash station on top of the IBC

This is the simplest plumbing of all. The washer drum sits straight on top of the waste IBC and drains down through the IBC's own 150 mm top opening: no pipe, no pump and no slope needed. Choose it in the calculator's "Getting waste to the IBC" box to see the drawing.

  • Mounting: unscrew the IBC's top lid. Bolt two 90 × 45 bearers across the top of the steel cage with galvanised U-bolts, then sit the cut-down drum (about 500 mm tall) on them. Its 100 mm outlet drops into the 150 mm opening through a rubber collar, so smell and flies stay in.
  • Vent: drill a separate 50 mm hole in the IBC top with fly mesh, since the fill opening is now taken.
  • Height: the IBC is ~1160 mm tall, so the drum rim ends up at about 1.65 m. Build a work platform 600 mm high beside it, with 3 steps and a handrail. That puts the bucket at about 1.05 m above your feet, much like the stand version. The foot pedal goes on the platform.
  • Lifting buckets up: carry empties up the steps one at a time, or use a short roller ramp or a sack trolley on the steps. Never carry a full bucket up there, because it's emptied at the holding bay first.
  • Emptying: the truck connects to the bottom camlock as usual. To move the IBC, unbolt the drum (two people) or lift the whole lot together on pallet forks once it's empty.
  • Watch the level: you can't see the top of the liquid easily, so rely on the painted fill scale on the side, and book the truck at 80%.

Safety

  • The waste is blackwater. Pressure-washing makes a fine mist that carries germs, so keep the lid shut while it blasts. The operator wears a face shield, gloves, a waterproof apron and gumboots.
  • Set the station downwind of camp, well away from the kitchen, with a hand-wash station right beside it.
  • Never open the lid while the pump is running. Fit a sign: "LID DOWN · THEN PEDAL".
  • Wipe the lid, grid and pedal with a cleaner at the end of each shift.

🛒 Shopping list & where to get it

Prices are rough NZD guesses, so confirm them in store. The stores are on the Kitchen sand trap tab. A Kärcher service agent or outdoor power shop in Palmy can match the gun adaptor, and some stock rotary drum-cleaning nozzles.

🪱 Worm farm

Design

  • Lined timber bays, raised on concrete blocks, about 600 mm of bedding depth. Bay size and count come from the Planner.
  • Timber: use untreated macrocarpa (or other untreated timber) wherever wood touches bedding. CCA/ACQ-treated pine leaches copper and arsenic that harm worms and end up in the compost. Treated H4 timber is fine for the legs and the outer frame outside the liner.
  • Liner: 250 µm black polythene or pond liner, stapled to the inside walls. The floor falls 1:50 to a 20 mm tank outlet + tap at one corner. Leachate is collected, not let into the soil. That matters with human waste.
  • Drainage layer: 50 mm of coarse wood chip, with shade cloth on top so bedding doesn't block it.
  • Lid: 12 mm ply with 50 mm polystyrene glued underneath. It keeps out rain and frost in winter and heat in summer. Hinge it at the back, and fit a prop stick and a fly-meshed vent slot.
  • Rodent proofing: fit 6 mm galvanised mesh over vents, and keep the lid tight-fitting.
  • Site: full or afternoon shade (under deciduous trees is ideal: shade in summer, sun in winter). Keep it out of hollows that flood and sheltered from the prevailing westerly. Allow at least 20 m from streams/drains and 50 m from bores (confirm with Horizons).

Worms

  • Tiger worms (Eisenia fetida) and red worms (Lumbricus rubellus / Dendrobaena), sold by NZ worm farms by the kg. Garden earthworms won't live in compost.
  • Start the beds at least 3 months before the first festival on aged horse/cow manure + shredded cardboard. The population roughly doubles every 2–3 months in good conditions.
  • Stock at about 1 kg/m² minimum (2 kg/m² is better). The Planner shows how much to buy.
  • Ideal conditions: 15–25 °C, as moist as a wrung-out sponge, pH 6.5–7.5, dark, and plenty of air.
  • Year-round food: aged horse or cow manure (never from animals drenched in the last 4–6 weeks, because ivermectin-type dewormers in dung kill worms), cardboard, leaves, coffee grounds, and festival food scraps (no meat, dairy, citrus, onion or oil).

How to feed the toilet material

  1. Only feed material that has rested 6–8 weeks in the holding bay and no longer smells strongly of ammonia. Sniff test: earthy or mild is OK, while sharp, eye-watering or rotten is not ready.
  2. Spread it in a 5–8 cm layer over half the bed only. The worms then have a safe half to retreat to if it heats up.
  3. Mix in a little shredded cardboard if it's wet, and cover with damp cardboard or straw.
  4. Check after 3–5 days. If worms have moved into it, good. If the layer is hot (above 30 °C on a probe thermometer), don't add more.
  5. Only add the next layer once the last one is mostly eaten (2–4 weeks in summer, 6–8+ in winter). Use the monthly plan as a guide.

Cut list (per bay)

Includes a single holding bay of the same construction (1.2 × 1.2 × 1.0 m) in the Planner's count. It's built like a worm bay, just deeper and with no worms.

Harvesting

Twice a year, best in late spring and late summer. Stop feeding one end of a bay for 6 weeks and feed only the other end, so worms migrate across. Then shovel out the finished end. Alternatively, tip the cast into heaps in bright light; worms dive down, and you scrape off the top. Cure the harvested cast in a covered heap or bags for 6 more months (12 months total from toilet to use is the safety target). Sieve it through 6–10 mm mesh and return any worms to the bed.

🚰 Kitchen sand trap

→
🌾 PaddockOnly filtered water leaves the bottom, through slotted coil in a gravel trench. It soaks in below the grass.

The barrel is a catchment, not a treatment plant. It keeps solids, fat and food out of the paddock, and the soil does the rest. Never run toilet waste or urine through it.

How it fits together (cross-section)

The heights are to scale and the lengths are shortened. On a phone, scroll sideways to see the whole drawing.

🧮 Size it

Rough rules of thumb: about 100 L/day per barrel before the chip layer blinds up too fast, and trench soakage of 5–25 L per m² of trench floor per day depending on soil. Pipe fall needs to be at least 1:40 (25 mm per metre). Watch how it behaves on day one and add a second barrel if water sits on top for more than an hour.

Inside the barrel (top → bottom)

  1. Lid: the drum's clamp lid, or ply with fly mesh. It keeps rain, kids, dogs and flies out.
  2. Side inlet at 780 mm: a 65 mm tank-outlet fitting in the side wall, about 80 mm above the chip, so the pipe doesn't need to climb over the lid.
  3. Splash plate: a paver or tile on the chip under the inlet, so the stream doesn't dig a hole in it.
  4. Untreated wood chip or bark, 100 mm: the "sacrificial" layer. It catches the fat and food. Rake it daily and swap it when it goes slimy.
  5. Shade cloth or geotextile disc: lets you lift the chip off without taking the sand with it.
  6. Coarse washed sand, 400 mm: concrete or "plasterer's coarse" sand. Not fine builder's sand, and not beach sand (salt).
  7. Pea gravel 7–10 mm, 100 mm: stops sand washing into the gravel below.
  8. Drainage gravel 20 mm, 100 mm: around the outlet fitting.
  9. Outlet: a 50 mm tank outlet (bulkhead) fitting, 50 mm above the drum floor, into the slotted coil.

Build steps

  1. Pick a sturdy tree downhill of the kitchen, at least 20 m from any stream, drain or water trough, and away from where people camp or walk. Without burial, the only thing that makes the water flow is height: the sink outlet has to end up higher than the barrel's side inlet (plinth + 780 mm), plus the fall. Use the calculator. On flat ground, raise the sink bench or choose a tree further downhill.
  2. Drill the barrel side with a hole saw: the 50 mm outlet 50 mm up from the floor on the downhill side, and the 65 mm inlet 780 mm up on the kitchen side. Fit both tank outlets with their seals and silicone them. Fill it with water to check it doesn't leak.
  3. Make a level plinth right against the tree from 2–4 pavers on compacted gravel. A full barrel weighs around 300 kg, so check it with a spirit level both ways. Dig the trench starting about 1 m from the barrel and leading away from the tree (to spare the big roots) across the paddock along the contour. Make it 450 mm wide with an almost level floor (a slight fall away is fine), so it spreads the water along its full length.
  4. Stand the empty barrel on the plinth and strap it to the tree with two ratchet straps (about ¼ and ⅔ of the way up). Put carpet offcuts or rubber between the straps and the bark so you don't ring-bark the tree. A full barrel that tips over is 300 kg of wet sand, so pull the straps tight. Push the slotted, socked coil onto the outlet, let it curve down into the trench, and lay it on 100 mm of gravel. Cover it with 200 mm more gravel and shade cloth, then put the soil and turf back. Cap the far end.
  5. Fill the barrel with the layers above. Re-tension the straps once it's full and wet, because the load settles.
  6. At the sink, fit the basket strainer waste and the 40 mm trap. Use the adaptor to go onto the unslotted coil. Run it to the barrel's side inlet with a steady fall and no dips. Peg the coil every metre so it can't sag.
  7. Test: pour 3 buckets of water down the sink. It should drain freely, nothing should pond above the chip after a few minutes, and the trench end should stay dry on top.

Keep it working

  • Fat is the enemy. Wipe greasy pans and plates with paper towel or bread into the bin before washing, and never pour hot fat or oil down the sink. Collect it in a tin and take it to waste.
  • Empty the sink strainer into the food scraps bin after every wash-up. Vegetable scraps can go to the worm farm (no meat, dairy, citrus, onion or oil).
  • Use biodegradable, phosphate-free dish liquid. No bleach, caustic drain cleaners or disinfectant down the sink.
  • Every morning: lift the lid, rake the chip, and check for ponding. If water sits on top for more than an hour, swap the chip layer.
  • Have a bag of spare chip on site, at about 30 L per barrel for every 3–4 days.

After the festival

  • Let the barrel drain for a day, then lift off the chip layer and the top 50 mm of sand and add them to the toilet holding bay or a hot compost heap. Never put them in the worm beds directly, because of the fat.
  • Leave No Trace: scoop out the rest of the chip and sand (bag the clean sand to reuse next year), loosen and remove the straps and padding so the tree isn't harmed, and take the barrel and pavers away. Either lift the trench coil and backfill, or leave it in place if the farm owner agrees, with a waratah marking the line so nobody drives over it.
  • Replace all the sand every 2–3 years, or sooner if it drains slowly.

Rules

Kitchen wash water counts as greywater. Under Horizons' One Plan, small greywater discharges to land are usually allowed when they soak in below the surface, don't pond or run off, and are kept well back from water. Confirm the setback with Horizons and include the sand trap in the event plan. Never let it run onto the surface or into a drain or stream.

🧹 Sanitation team

Kiwiburn · Infrastructure Revision: September 2026

Sanitation Co-Lead: why does this role exist?

The Infrastructure Department exists to support the planning, development, operation and maintenance of the physical systems and shared infrastructure required for Kiwiburn.

The Sanitation team within Infrastructure exists to help keep Kiwiburn safe, functional and enjoyable by coordinating toilet and sanitation services, hygiene supplies, composting systems and volunteer operations required before, during and after the event.

The role of Sanitation Co-Lead exists to collaboratively guide and support the Sanitation team throughout the year and on site. The Co-Leads work together to plan, improve and deliver Sanitation services, support volunteers, maintain team knowledge and systems, coordinate with other Kiwiburn teams, and ensure leadership support throughout Build, the Burn and Packdown.

All Sanitation Co-Leads hold equal standing and shared responsibility for the overall success of the team. Co-Leads take the lead in agreed areas of work, while the distribution of responsibilities may change as team capacity, individual interests, availability, capability and the needs of each year's event evolve.

What is the team structure?

The Sanitation team operates through a collaborative Co-Lead structure. The number of Co-Leads may change depending on team capacity and operational requirements. The leadership work currently spans four broad focus areas. These describe where each Co-Lead generally takes the lead, not the limits of what they may contribute to. They are not fixed positions or rigid silos, and responsibilities may be redistributed between Co-Leads by agreement.

📋 Coordination

People, planning, communication, volunteer coordination and administrative systems that keep Sanitation organised.

Capabilities: strong organisational and administrative capability, including volunteer coordination, communication, rostering, record keeping, documentation, managing competing priorities and putting systems in place that help the wider team operate effectively.

🛠️ Logistics

Site logistics, Build and Packdown coordination, physical setup, contractor/site requirements and practical delivery of Sanitation assets.

Capabilities: practical hands-on capability, such as experience with building, repairs, DIY, tools, site work or similar environments; confidence assessing what materials, equipment and practical support are needed to complete physical tasks safely and effectively.

🪱 Stewardship

Care, safe use, maintenance and development of Sanitation assets, composting systems and related resources.

Capabilities: knowledge or experience relevant to composting, worm farming, waste systems, compostable toilets, environmental management or related areas. A person taking primary ownership of specialist Stewardship systems must either already hold the necessary knowledge or be willing and able to independently develop it, including seeking reliable external guidance where required.

⚙️ Operations

Systems, training, knowledge sharing and operational processes required to deliver Sanitation services effectively during the event.

Capabilities: strong planning, process-development, knowledge-sharing and people-management capability, ideally with experience in event operations, logistics, training, volunteer coordination or similar environments. This area requires the ability to turn operational knowledge into clear procedures, training and workable systems.

Co-Leads are not expected to have expertise across every area, but the Co-Lead team collectively needs sufficient capability across all four.

How are the responsibilities shared?

The Co-Lead team agrees how responsibilities are distributed each year. Each area should have clear ownership, appropriate cover and enough documentation for another Co-Lead to maintain continuity when the primary owner is unavailable.

Co-Leads are expected to maintain enough understanding of the wider Sanitation operation to provide continuity and cover where appropriate. Providing cover may include following documented plans, coordinating routine tasks, maintaining communications, supporting volunteers and escalating issues appropriately. It does not require a Co-Lead to undertake specialist or technical work outside their knowledge, training or competence.

Where a responsibility requires specialist knowledge or judgement, it should only be transferred to another Co-Lead who has, or has developed, the appropriate capability. If specialist expertise is unavailable within Sanitation, the covering Co-Lead should follow documented escalation pathways and seek support from the relevant Kiwiburn team where available.

All Co-Leads are expected to keep the procedures, plans, contacts and escalation pathways for the areas they primarily own clear and current so that routine work can continue without relying on one person's memory or availability.

What does this role entail?

As a Sanitation Co-Lead, you will:

  • Lead and support the Sanitation team in achieving its goals for the annual Kiwiburn event.
  • Work collaboratively with the other Sanitation Co-Leads, with equal standing in team leadership and decision-making.
  • Take primary responsibility for agreed areas of work while maintaining awareness of wider Sanitation activities.
  • Collectively ensure that all critical Sanitation functions have clear ownership and adequate cover, including when an individual Co-Lead is unavailable.
  • Keep the other Co-Leads informed of decisions, changes, risks or dependencies that may affect the wider Sanitation operation.
  • Support or provide cover for other Co-Leads where appropriate, using shared documentation, established procedures and team knowledge to maintain continuity.
  • Maintain clear, current and usable documentation for the areas you primarily own, including procedures, plans, task information, relevant contacts and escalation pathways.
  • Identify activities that require specialist knowledge or judgement and make sure their safety requirements, limits and escalation pathways are clearly understood and documented.
  • Participate in team planning, volunteer selection, event readiness and post-event review.
  • Recruit, support and communicate with Sanitation volunteers and help create an inclusive, welcoming and well-organised volunteer experience.
  • Communicate and consult with your team and wider Kiwiburn teams, as appropriate, on key decisions that affect them, and feed back to the Infrastructure Facilitator where required.
  • Help identify opportunities to improve Sanitation systems, assets, volunteer processes, documentation and event delivery.
  • Participate in the shared event Duty Lead/on-call roster, providing operational leadership and escalation support during agreed periods.
  • Contribute to the annual Sanitation Afterburn report and post-event review.
  • Assist in creating a collaborative and inclusive team culture where people are inspired to contribute and make a difference for the Kiwiburn community.

⏱️ How much time will I need to commit?

Time commitments are indicative and vary by focus area and time of year. On average it's approximately 1–3 hours per week year-round. From September to January this may increase to approximately 5–10+ hours per week, while February to April (post-event) may be approximately 2–5 hours per week. December–January is generally the busiest period, particularly around recruitment, planning, Build and final event readiness, at approximately 10+ hours per week. Co-Leads taking significant Build responsibility may be contributing several hours per day while onsite. May–August is generally quieter, at approximately 1–2 hours per fortnight for some Co-Leads, while Stewardship, working-bee or project-based responsibilities may require additional time.

🏗️ Prebuild
Not every Co-Lead is expected to attend the entire Build. Onsite responsibilities may be distributed or rotated between Co-Leads from year to year according to availability, interest, experience, capability and team planning. Some Co-Leads may arrive substantially earlier than others where their responsibilities require it.
🔥 Event
Co-Leads are expected to attend the Kiwiburn event. Where attendance is not possible, this should be discussed in advance and adequate leadership coverage agreed with the wider Co-Lead team and Infrastructure Facilitator should be set up. Attending Co-Leads participate in the shared Duty Lead/on-call roster, training and operational support. Duty Lead allocation should take account of each person's overall year-round, Build, event and Packdown contribution, availability and recovery needs so that workload remains equitable.
📦 Postbuild
Sufficient Sanitation leadership is expected to remain onsite while services continue and Sanitation assets are cleaned, collected or stored. Not every Co-Lead is expected to remain for the full Packdown period.
🐝 Other
Co-Leads may attend working bees, planning visits or other site activities relevant to their focus area. Appropriate coverage is agreed within the Co-Lead team.

👥 The four Co-Lead portfolios

People, Planning & Administration

Job purpose: own the people and administrative systems required to recruit, organise and retain the Sanitation team, ensuring volunteer applications, communications, rostering, records and planning processes remain organised and responsive throughout the year.

Primary ownership (13 areas)
  • recruitment advertising and volunteer re-engagement
  • applicant communications and application management
  • Portal administration
  • event roster construction
  • ticket allocation administration
  • volunteer communications
  • Sanitation records and Drive organisation
  • administrative maintenance of purchasing and procurement records
  • volunteer performance/history records
  • coordination of volunteer feedback after the event
  • general Volunteer Manual ownership
  • administrative coordination of documentation
  • maintaining visibility of deadlines and outstanding actions across the team

Managing documentation, coordination, applications, communications, the roster and Portal are all assessed as High workload, concentrated across September–January.

Event contribution: this person still rotates through Duty Lead coverage, participates in training and can act operationally onsite. The role should never become office-centric with no paddock understanding/experience.

Expected contribution profile
  • Active year-round, with the heaviest workload generally falling between September and January.
  • High contribution through recruitment, applicant management, volunteer communications, rostering, Portal administration and planning administration.
  • Expected to participate onsite during final event readiness, volunteer/Shift Lead training, Burn operations and Duty Lead coverage.
  • Expected to retain practical paddock familiarity rather than operating as an office-only role.

2027 current-holder availability: approximately 4–5 days before the Burn to support final Build and event-readiness activities.

Build & Site Logistics

Job purpose: lead Sanitation's physical Build and site logistics programme, ensuring toilets, Sanitation-owned physical assets and site facilities are positioned, prepared, functional and ready before the event. This role coordinates closely with Infrastructure, Plumbing, Town Planning, contractors and the other Sanitation Co-Leads where specialist or cross-department support is required.

Primary ownership (15 areas)
  • Build task planning
  • supervision of Build volunteers
  • deployment of Kiwiburn-owned portaloos
  • handwashing station setup and placement
  • menstruation station physical setup and placement
  • physical renovations and repairs
  • conduct the physical onsite stocktake during Build
  • identify missing or broken physical equipment and Build-specific requirements, and record these gaps in the shared stock/asset register
  • physical improvement projects
  • Town Planning coordination on placement/access
  • coordinate onsite contractor access, drop-off and physical positioning of rented portaloos
  • physical movement/placement of compostable toilet blocks in consultation with the Compost Co-Lead
  • Build & Packdown period coordination of specialist support

The workload profile is very concentrated. Build volunteer supervision is rated as Very High workload, with portaloo deployment, menstruation-station setup and toilet placement also carrying significant Build-period workload. Significant Build and Packdown contributions will be taken into account when allocating Duty Lead coverage during the Burn.

Expected contribution profile
  • Moderate year-round planning and coordination, with a highly concentrated workload during the January Build period.
  • Expected to have significant early-January onsite availability and to coordinate Build volunteers and physical site setup.
  • Expected to participate in Burn operations and Duty Lead coverage, with substantial Build and Packdown contribution recognised when Duty coverage is allocated.
  • Maintains enough year-round visibility to plan Build requirements, site dependencies and physical improvement work before arriving onsite.

Compost, Assets & Stewardship

Job purpose: maintain the long-term health, safety and functionality of Sanitation's composting systems and physical assets, with particular responsibility for the worm farm, compostable toilets, working bees and year-round asset stewardship.

Primary ownership (16 areas)
  • worm farm stewardship
  • worm farm inspections and maintenance planning
  • compostable toilet systems
  • barrel condition and readiness
  • compost toilet preparation and shutdown
  • compost procedures and training
  • sanitation-specific contamination/H&S procedures in collaboration with Site Safety
  • asset condition assessments
  • asset register ownership
  • planned maintenance
  • working-bee Sanitation priorities
  • physical asset storage condition
  • compost-related improvement projects
  • long-term maintenance requirements

This role also carries specialist event-readiness responsibilities such as compost training and safe handling procedures.

Relationship with Build: Build owns how physical infrastructure gets installed or repaired. Compost/Assets owns what condition the compost/assets systems need to be in and how those systems should operate. Moving a compost toilet block = Build primary. Determining where/how that compost system needs to operate = Compost primary. Designing a better physical movement system = joint project.
Expected contribution profile
  • Periodic year-round onsite responsibility to perform inspections at working bees, maintenance planning and asset stewardship.
  • High contribution around working bees and Build, particularly for worm-farm condition, compost-system readiness and sanitation asset maintenance.
  • Carries specialist event-readiness responsibilities including compost procedures, training and safe-handling requirements.
  • Expected to participate in Burn operations, Duty Lead coverage and Packdown, particularly where compost systems and Sanitation-owned assets require specialist oversight.

Event Operations & Logistics

Job purpose: design and coordinate Sanitation's event operating system so that Shift Leads and volunteers can run routine sanitation services independently, with Co-Leads required primarily for exceptions, escalations and higher-level decisions.

Primary ownership (18 areas)
  • Event Operating Plan
  • Shift Lead development
  • Shift Lead Handbook
  • Shift Lead briefings
  • Duty Lead roster coordination
  • Can-Am operating/induction system
  • radio procedures
  • shift escalation rules
  • overall stock forecast, event consumable quantities and routine stock-cache system
  • consolidation of Build stocktake findings and operational needs into the shared procurement plan
  • coordination of operational procurement requirements within the approved budget and purchasing process
  • portaloo contractor relationship management, including requirements, booking, quantities, servicing schedule, contact details and additional servicing
  • live servicing arrangements
  • event logistics
  • Duty Lead handover/logging system
  • operational incident logging
  • Packdown coverage planning
  • portaloo contractor Packdown collection and handover

This role must own the operating system, not personally operate everything. The Event Operations Co-Lead is responsible for designing, maintaining and coordinating these systems; routine delivery should be delegated to trained Shift Leads, volunteers and the current Duty Lead wherever appropriate. The Event Operating Plan and Duty Lead coverage are both high-intensity responsibilities, with the operational workload peaking in the final planning period, during the Burn and into Packdown.

Expected contribution profile
  • Increasing workload from late in the year through the Burn, with particularly high responsibility during final event planning and readiness.
  • Strong onsite involvement during the event, focused on maintaining the systems that allow Shift Leads and volunteers to operate independently.
  • Owns preparation of live operational systems but does not become the default person executing routine shift work or carrying all Duty Lead coverage.
  • Expected to contribute to Packdown planning and contractor/service handover after the Burn.

What shared experience and qualities are needed?

  • Strong communication and collaboration skills, with the ability to work constructively as part of a shared leadership team.
  • Comfortable taking ownership of agreed responsibilities while keeping others informed and asking for support where required.
  • Good organisational, planning and problem-solving skills.
  • Able to manage changing priorities and make practical decisions in a busy volunteer environment.
  • Project and time management skills for yourself and the people or projects you support.
  • Willingness to learn about the wider Sanitation operation, follow established procedures and provide appropriate cover outside your usual focus area when required.
  • Comfortable working with volunteers with different levels of experience, confidence and availability.
  • Aware and proactive in managing your own capacity, including communicating early when workload or life commitments affect your ability to deliver.
  • Comfortable learning and using systems such as Google Drive, Slack and Kiwiburn Portal, as well as other volunteer/rostering tools, with regular access to a computer and internet.
  • Available and responsive regularly year-round via email and Slack, or able to ensure there is adequate cover when unavailable.
  • Willing to work collaboratively with Infrastructure and other Kiwiburn departments.
  • Understanding of Te Tiriti o Waitangi (Treaty of Waitangi) and how it relates to the Kiwiburn Organisation. Please refer to the Memorandum of Understanding for more information.
  • A positive, motivated, inspired attitude and a cheeky twinkle in your eye!

What would be helpful to bring?

  • Previous experience coordinating, leading or supporting a team of people with different workloads and priorities. Bonus points if they are volunteers!
  • Prior volunteering for Kiwiburn, onsite or year-round.
  • Familiarity with Kiwiburn's organisational structure and event environment.
  • Experience in event operations, volunteer coordination, practical site work, environmental systems, documentation, training or other areas relevant to the Co-Lead focus you are interested in.
  • Experience creating clear processes, documentation or training material.
  • Interest in improving systems rather than simply repeating how things have previously been done.
  • Desire to serve the burner community.

On site capability

Co-Leads are expected to develop a broad working understanding of Sanitation operations and undertake relevant training so they can support the wider team, follow established procedures and provide continuity across focus areas where appropriate.

Some Sanitation responsibilities require specialist technical or practical knowledge. Co-Leads are not expected to undertake work outside their competence simply to provide cover. Where specialist expertise is required, the appropriate Co-Lead or another suitably experienced Kiwiburn team should be consulted.

Individual physical ability should not prevent someone from contributing effectively as a Co-Lead. Tasks may be shared or allocated according to skills, accessibility requirements, training and capacity, provided the Co-Lead team collectively maintains appropriate operational coverage.

Who else will I be working with?

  • Infrastructure Facilitator
  • Other Sanitation Co-Leads
  • Infrastructure teams including Town Planning, Plumbing and MPW
  • Crew Support, Volunteer and other teams whose work overlaps with Sanitation
  • Sanitation Shift Leads and event volunteers
  • Site Office and relevant onsite operations teams
  • Site Safety / Health & Safety teams where required
  • External contractors and suppliers as required

The relevant Co-Lead may communicate directly with another team or department regarding their area of work; communication does not need to be routed through a single Sanitation representative.

🛠️ Problems & fixes

🧤 Safety, health & rules

Pathogens: why handling and timing matter

Human faeces can carry E. coli, Salmonella, Campylobacter, norovirus, Hepatitis A, Giardia, Cryptosporidium and worm eggs (e.g. Ascaris, the hardiest). Vermicomposting reduces them a lot but doesn't sterilise. Time is the main safety factor: aim for 12 months or more from the toilet to using the compost. Use it only around trees, shrubs, ornamentals and pasture margins, not on vegetables eaten raw, and not within a month of grazing.

Crew handling rules

  • Wear nitrile or heavy rubber gloves, long sleeves, and closed shoes or gumboots. Wear eye protection when tipping buckets.
  • Two people per full bucket, or use a sack trolley. A full 50 L bucket can weigh 40+ kg, which is why the planner fills to ~65%.
  • Use a dedicated "dirty" wheelbarrow, shovel and fork, painted a different colour, and never use them for food areas.
  • Wash hands with soap after every handling session and before eating or smoking.
  • Keep vaccinations current: tetanus, and consider Hepatitis A for regular handlers.
  • Keep a spill kit: sawdust, a shovel, bags, gloves and diluted bleach for hard surfaces only (never into the buckets or beds).
  • Anyone with diarrhoea or vomiting should stay off handling duty. Report gastro outbreaks on site to the festival medic and the public health unit.

Steel buckets

  • Galvanised steel corrodes from urine salts and acidic compost. The zinc ends up in the compost and the buckets rust through within a few seasons. Prefer stainless (food-grade 304), or epoxy-paint the inside of galvanised buckets.
  • Put a 3–5 cm layer of sawdust in the bottom of every empty bucket. It stops sticking and soaks up liquid.
  • Use tight lids for transport. Never stack full buckets more than 2 high.
  • Wash after emptying at the bucket wash station (mouth-down over the spinning nozzle, lid shut), then leave them upside down in the sun to dry.
  • Number every bucket and log its fill date, so the holding bay can be loaded in order.

Council & regional rules (check before building)

  • Rangitīkei District Council: composting toilets are normally covered by the NZ Building Code (clauses G1 Personal hygiene and G13 Foul water) and the AS/NZS 1546.2 standard for waterless composting toilets. Temporary event toilets may be handled under the event permit instead. Ask the council's building and environmental health teams early.
  • Horizons Regional Council (One Plan): discharging human waste, urine or leachate to land has setback and volume conditions. The lined bays with collected leachate are designed to make compliance easy, but confirm before the first event.
  • Event health requirements usually set the number of toilets per attendee and the hand-wash requirements. Your festival's event management plan should reference this system.
  • Keep a simple log book (bucket counts, holding-bay dates, feeding dates, harvest dates, where compost was used). Council officers like it, and it makes troubleshooting easy.

This page is planning guidance, not legal advice. Rules and setback distances differ by site, so confirm them with both councils.
