How much water do you need per person per day at Burning Man?
Plan for roughly 6 to 8 gallons of water per person per day in an RV at Burning Man, and showers are the single biggest variable. At a typical 1.6 gallon-per-minute shower head running about three minutes, one person uses close to five gallons just rinsing off — before any water for drinking, cooking, dishes, or flushing.
Most of that water comes straight back out as greywater, so your gray tank is what fills first. Cutting shower time, fitting a low-flow head, or taking “navy showers” (water off while you lather) is the fastest way to stretch both your fresh supply and your tank capacity. Women and men tend to use noticeably different amounts, which is why Poo Math models each person separately.
To turn the per-person figure into a plan, multiply by your crew size and the number of nights, then compare it against your rig’s fresh, gray, and black capacities. Poo Math does that math for you and schedules water deliveries and pump-outs so you never run dry or overflow.
