TOWN OF LAMAR WWTP - Carters Crossroads, South Carolina Wastewater Treatment Plant

TOWN OF LAMAR WWTP is a municipal wastewater treatment facility located in Carters Crossroads, Darlington County, South Carolina. It serves a population of approximately 3,700 people, placing it in the small-to-medium agglomeration category under US regulatory frameworks. As a US facility, the plant is subject to the Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the South Carolina Department of Health and Environmental Control. These permits set effluent limits based on the receiving water body's designated uses and typically require secondary treatment as a minimum standard for municipal plants of this scale. The plant's treated effluent discharges into local waterways that are part of the Pee Dee River basin, ultimately draining to the Atlantic Ocean. The surrounding area is primarily rural and agricultural, with the plant playing a key role in protecting local surface water quality and downstream ecosystems.

The plant discharges into tributaries of the Pee Dee River, which flows through South Carolina into Winyah Bay and the Atlantic Ocean. This watershed supports diverse aquatic life, including fish and shellfish populations important to regional ecology and local fisheries. The plant's treatment performance directly affects nutrient and pathogen levels in these waters.
