United StatesNorth AmericaWater for the World: Operating and Maintaining Septic Tanks
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
