change:WATER Labs is developing a toilet that can be deployed to every vulnerable household. We are developing a revolutionary evaporative ("self-flushing") toilet-a low-cost, compact, off-grid, portable solution that decouples household toilet access from sewerage infrastructure. Our evaporative toilet rapidly shrinks onsite sewage accumulations down to 5-10% of produced daily volumes. Sewage is 85-99% water. By cheaply, quickly eliminating that water, we eliminate 90% of the sewage problem.
