'Mexico City’s water system goes against its own functional essence. The city is dehydrating itself. We’re mixing our water with poisonous waste and then pumping it out through a complex network of pipes. Just like what happens when a human is dehydrated, Mexico City has diarrhea.' — Elias Cattan — Quartz
It works like this: people empty their latrines into a sewage receptacle (currently, latrines are often emptied into rivers), the waste gets funneled through a series of tubes and is pressurized at extreme temperatures, and the byproduct is clean, possibly drinkable water. Deshusses describes the process as “a pressure cooker on steroids.” — wunc.org
