Every shower creates a second logistics problem: used water. A shower is ready only when its floor, drain, storage, treatment, transport, and final disposal path are ready.
Official rule: Gray water must not be discharged onto the playa. That includes water used for bathing, washing, cooking, or dishes, even when the soap is marketed as biodegradable.
Start with gray-water capacity
- Use the least water that meets the need.
- Put the shower or wash station inside secondary containment.
- Route every drop into a closed, stable, labeled container.
- Size storage for showers, handwashing, dishes, cooler melt, leaks, and a reserve.
- Keep clean water and gray-water tools physically distinct.
- Choose a verified pump or legal off-site disposal path before departure.
- Stop water-generating activities immediately if the system leaks or loses capacity.
Official guidance: The 2026 Survival Guide says public pools and showers are not permitted and recommends a portable shower only with a system to collect and manage gray water. Burning Man Project’s gray-water page does not recommend simple flat evaporation ponds.
Options and tradeoffs
- Sponge bath or wipes: lowest water volume, but all used material still needs pack-out.
- Low-flow bag or pump shower: comfortable and measurable, but needs a stable enclosure and complete drain capture.
- Closed haul containers: simple to understand, but heavy and prone to slosh or expansion if overfilled.
- Engineered evaporation device: may reduce haul volume, but needs tested capacity, containment, maintenance, and a backup. Do not treat a sheet of plastic on the playa as a plan.
- Approved on-site pumping: reduces transport, but schedules can slip and capacity must last through a delay.
Playa tip (community practice - not an official requirement): Measure one real shower at home by catching the outflow. Use that result, not the shower bag's nominal size, to calculate storage.
Common mistakes
- The drain hose can pop loose or sits higher than the collection point.
- Dust blocks a filter and causes an overflow.
- A container is too heavy to lift safely when full.
- Gray water is stored in a vessel that could be confused with potable water.
- Pumping is scheduled for the last usable day with no delay buffer.
- The return vehicle cannot carry full containers upright and secured.
Test before departure
Assemble the complete shower and drain system over a dry surface. Run the maximum expected flow, deliberately block the filter, and inspect every joint. Fill transport containers with clean water to verify weight, seals, tie-downs, and return-space geometry.
