      Without access to large livestock the inhabitants of Lake Texcoco needed a source of fertilizer. The only available option at scale was night soil (human dung). This led to a contender for the worst job in history, dung collector. Dung was collected at designated sites (public toilets) and transported via canoe to either farms or at large dumping (pun not intended) sites to be purchased at market.
