Toilets that are culturally appropriate, as well as safe and sustainable, could take different forms in different contexts. Sophisticated sewage systems might make the most sense in densely populated cities, where inadequate waste treatment wipes out riverine life. But elsewhere, well-drained and -managed pit latrines that minimize flies might be the most appropriate option. (A favorite of Wald’s is the “arborloo”: Once this composting, shallow pit latrine is full, a tree is planted in the spot, and the toilet is moved to a new location.)
