Palestinian sewage dyke collapses burying people in shit. Turns out their sewage processing infrastructure was overloaded by overcrowding and they started storing it in lagoons.

Aid officials said plans to build a larger waste treatment facility had been held up for years by perpetual fighting in the area.

The Gaza City mayor blamed the collapse on local people digging out dirt from the structure and selling it to building contractors.

Now imagine if these cities were built using composting toilets. Low disruption installation processes mean that you don’t have to wait for the fighting to stop to expand your toilet capacity. Individual ownership means that people won’t be consuming communal resources personally trying to survive, with disastrous results. Distributed infrastructure has political implications.
