In an illustration I made for the artists' collective SIMPARCH, a neighborhood of "spontaneous architects" deploys simple and inexpensive technologies that largely free it from corporate and municipal dependency. This community uses its household effluent to irrigate garden plots, and makes its own fertilizer with composting toilets. With these toilets, residents separate their water from waste at the outset--transforming both into useful commodities and circumventing the need for sewage treatment. Their rooftop distillation devices, furthermore, turn any effluent into perfectly drinkable water by passive solar power alone.
