Falls City WWTP - Secondary Treatment Plant in Falls City, Texas

Falls City WWTP is a municipal wastewater treatment facility located on Front Street in Falls City, Texas, within Karnes County. The plant serves a small population of 350 residents, reflecting the rural character of the community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal plants discharging to surface waters. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 246.05 units and an average daily discharge of 230.91 units, the facility operates near its capacity, indicating consistent demand from the local population. The plant's discharge volume suggests it effectively manages the wastewater generated by the community. The treated effluent is discharged into a local waterway that ultimately drains into the San Antonio River basin, which flows to the Gulf of Mexico. This connection to the Gulf underscores the importance of maintaining treatment standards to protect downstream aquatic ecosystems and coastal water quality. The plant's inland location reduces direct marine impact but still contributes to the overall health of the watershed.

The plant discharges into a tributary of the San Antonio River, which flows southeast through Texas and empties into the San Antonio Bay on the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and migratory birds, and is ecologically sensitive to nutrient loading. The secondary treatment provided helps reduce organic pollutants, but the small population served limits the overall nutrient load compared to larger urban facilities.
