Water for the World: Operating and Maintaining Aqua Privies
U.S. Agency for International Development
An aqua privy is an underground watertight vault filled with water that receives excreta and washwater from a drop-pipe, allows solids to settle to the bottom, and discharges effluent to a soakage pit. This technical note describes how to operate and maintain an aqua privy.Read more

United StatesNorth AmericaWater for the World: Designing Stabilization Ponds
U.S. Agency for International Development
A stabilization pond is a large shallow excavation that receives sewage from a sewage system, detains the sewage so that biological processes can destroy most of the disease-causing organisms, and discharges the effluent as treated sewage. This technical note describes the basic design of a...Read more

U.S. Agency for International Development
A septic tank is a self-operating unit for sewage treatment. The tank receives raw sewage from a building, allows solids to settle out, and discharges effluent to an underground (subsurface) absorption system for final disposal. This technical note describes how to measure scum and sludge depths to...Read more
