Santa Anna WWTP is a municipal wastewater treatment plant located in Coleman County, Texas, United States. It serves a small population of 1,410 residents, reflecting its role in a rural or small-town community. The plant is situated inland, far from coastal areas, and operates under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level required by the US Environmental Protection Agency (EPA) for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant's designed capacity is 567.81 units, and it currently discharges 529.96 units, indicating it operates below its full capacity. The treated effluent from Santa Anna WWTP is discharged into local waterways that ultimately drain into the Colorado River basin in Texas.

The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits, ensuring compliance with water quality standards to protect the receiving environment.

Santa Anna WWTP discharges into tributaries of the Colorado River in Texas, which flows southeast to the Gulf of Mexico. The Colorado River basin supports a variety of fish species and provides critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient loads and organic pollutants, mitigating potential impacts on downstream water quality and aquatic ecosystems.
