Stabilization pond
![Schematic of Waste Stabilization Ponds (WSPs): They are large, man-made water bodies and can be used individually, or linked in a series for improved treatment. There are three types of ponds, (1) anaerobic, (2) facultative and (3) aerobic (maturation), each with different treatment and design characteristics.[1]](/Images/godic/202502/20/Schematic_of_the_Waste_Stabilization_Pond_(WSP)1340.jpg")

Stabilization ponds (also called lagoons or waste stabilization ponds) use a natural process for wastewater treatment that employs a combination of macrophytic plants, substrates and microorganisms in a more or less artificial pond to treat wastewater. The technique is frequently used to treat municipal wastewater, industrial effluent, municipal run-off or stormwater. After treatment, the effluent may be returned to surface water or reused as irrigation water (or reclaimed water) if the effluent quality is high enough.
