HOLLANDALE POTW - Hollandale, Mississippi Wastewater Treatment Plant

HOLLANDALE POTW is a municipal wastewater treatment plant located in Hollandale, Washington County, Mississippi. It serves a population of approximately 3,576 residents, providing secondary treatment to meet state and federal water quality standards. The plant is part of the region's infrastructure for managing domestic wastewater in a rural agricultural setting. The facility operates with a designed capacity of 3,312.23 million gallons per day and currently treats an average daily flow of 734.37 million gallons, indicating available capacity for future growth. As a secondary treatment plant, it utilizes biological processes to reduce organic matter and suspended solids, complying with the US Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit requirements. Treated effluent from HOLLANDALE POTW is discharged into a local waterway that ultimately drains into the Mississippi River, a major river system that flows into the Gulf of Mexico. The plant plays a key role in protecting downstream water quality and aquatic habitats in the Mississippi Delta region, an ecologically important area for migratory birds and diverse fish species.

HOLLANDALE POTW discharges into a tributary of the Mississippi River, which flows south through the Mississippi Delta to the Gulf of Mexico. The Delta region supports diverse aquatic life and serves as a critical migratory corridor for waterfowl. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf, an area of seasonal low oxygen that affects marine ecosystems.
