Water for the World: Designing a System of Two or Three Stabilization Ponds
U.S. Agency for International Development
A system of stabilization ponds is an arrangement of two or more ponds connected by pipes that receives sewage, detains it so that biological process can destroy most of the disease-causing organisms and discharges the effluent as treated sewage. This technical note describes the basic features of...Read more

United States, North AmericaWater for the World: Planning Combined Washwater and Excreta Disposal Systems
U.S. Agency for International Development
Combined washwater and excreta disposal systems may be appropriate where large quantities of washwater are generated and where resources are sufficient to establish and maintain such systems. This manual provides a comprehensive guide to recognizing where a combine disposal system would be most...Read more

United States, North 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

United States, North AmericaWater for the World: Operating and Maintaining Mechanically Aerated Lagoons
U.S. Agency for International Development
A mechanically operated lagoon is a large, lined excavation that receives sewage, mixes it with oxygen so that biological processes can destroy most of the disease-causing organisms, and discharges the sewage as treated sewage. Correct operation and maintenance is important because a neglected...Read more

United States, North AmericaWater for the World: Operating and Maintaining 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. Correct operation and maintenance is important because a...Read more

Egypt, Arab Rep., Middle East and North AfricaGuidelines for Gravity-Fed Drip Irrigation on Slopes in Myanmar
iDE
This guide from Proximity Design (formerly iDE Myanmar) outlines considerations for using low-pressure drip irrigation kits on stepp and gentle slopes. While not as easy as installations on flat ground, it is still possible to use drip irrigation very effectively on crops grown on sloping land.Read more
