Grantville WPCP No4 - Secondary Wastewater Treatment Plant in Grantville, Georgia

Grantville WPCP No4 is a municipal wastewater treatment plant located in Grantville, Georgia, United States. The facility serves a small population of 328 residents, reflecting its role in a rural community within Coweta County. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids from wastewater. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Georgia Environmental Protection Division, governs its discharge limits and monitoring requirements. With a designed capacity of 113.56 million gallons per day and an actual discharge volume of 37.85 million gallons per day, the plant operates well below its capacity. The treated effluent is discharged into a local water body, which ultimately drains into the Chattahoochee River basin. The Chattahoochee River flows through Georgia and Alabama before emptying into the Apalachicola Bay in Florida, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's secondary treatment helps protect downstream water quality and aquatic life.

The plant discharges into a local stream that is part of the Chattahoochee River watershed. The Chattahoochee River flows through the Piedmont region of Georgia, supporting diverse fish and invertebrate communities. Downstream, the river forms the border between Georgia and Alabama and eventually reaches the Apalachicola Bay, a productive estuary in the Florida Panhandle. The plant's secondary treatment helps reduce nutrient and organic loading, protecting downstream water quality and aquatic habitats.
