# Sanitation When Plumbing Fails More people die after a disaster from sanitation failures than from the event itself. This is the least glamorous preparation and close to the most important. ## The twin-bucket system Use two buckets: one for liquid waste, one for solid. Separating them is the whole trick — mixed waste is what produces the smell and the pathogen load. Line the solid bucket with a heavy bag and cover each use with a scoop of an absorbent carbon material: sawdust, peat moss, coconut coir, or shredded paper. Seal and remove the bag when it is roughly two-thirds full. ## Siting a latrine If you must dig, place a latrine at least **200 feet (60 meters)** from any water source, and downhill from it. Dig it at least 6 inches deep, cover after each use, and do not site it anywhere water pools after rain. ## Handwashing A tippy-tap — a jug on a string with a foot lever — uses a fraction of the water of pouring and is the single highest-value sanitation build. Soap and running water beat hand sanitizer against the organisms that matter here.
