Jemison WWTP is a municipal wastewater treatment facility located in Jemison, Chilton County, Alabama, United States. The plant serves a small population of 101 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all wastewater discharges.

The designed capacity of the plant is 567.81 cubic meters per day, with a current discharge volume of 189.27 cubic meters per day, indicating ample capacity for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Alabama River basin. The Alabama River flows into the Mobile River and then into the Gulf of Mexico, supporting diverse aquatic ecosystems. The plant's location inland, more than 50 km from the coast, reduces direct marine impact but still plays a role in protecting downstream water quality.

The treated effluent from Jemison WWTP enters local streams that are part of the Alabama River watershed. The Alabama River flows southward to meet the Tombigbee River, forming the Mobile River, which discharges into Mobile Bay and the Gulf of Mexico. This watershed supports a variety of aquatic life, including fish and invertebrates, and is important for regional biodiversity. The plant's secondary treatment helps reduce nutrient and organic loads, protecting downstream water quality in this ecologically sensitive river system.
