The Jackson Water Treatment Ponds are a series of artificial ponds located in Jackson, Clarke County, Alabama, designed to treat and purify municipal wastewater before it is discharged into the nearby Tombigbee River. The system comprises of four ponds that are interconnected and operated in series, with each pond providing a specific treatment process to remove pollutants from the water.
The first pond, called the primary settling pond, allows solids to settle and separate from the water. The second pond, the facultative pond, uses aerobic and anaerobic processes to break down organic matter and further remove pollutants. The third pond, the maturation pond, provides additional treatment by promoting the growth of microorganisms that further break down pollutants. The final pond, the polishing pond, provides the final stage of treatment before the water is discharged.
