Valley Mills WWTP is a municipal wastewater treatment plant located in Valley Mills, Bosque County, Texas. It serves a population of approximately 1,200 residents, classifying it as a small-scale facility within the state's wastewater infrastructure. The plant is situated inland, away from coastal zones, and its operations are governed by the US Clean Water Act and Texas Commission on Environmental Quality (TCEQ) regulations. The plant provides secondary treatment, which is the standard level required by the Clean Water Act for most municipal facilities. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 564.02 megaliters per year and currently discharges 454.25 megaliters annually, indicating operational capacity below design limits. The treated effluent is discharged into local waterways that ultimately drain into the Brazos River basin, a major river system in Texas flowing into the Gulf of Mexico. The plant plays a key role in protecting the water quality of the Brazos River watershed, which supports diverse aquatic life and provides water for agriculture and communities downstream. Its secondary treatment helps reduce nutrient and pollutant loads, contributing to the ecological health of the region.

The plant discharges into local tributaries of the Brazos River, which flows southeast through Texas to the Gulf of Mexico. The Brazos River basin supports a variety of fish species and provides critical habitat for migratory birds. The plant's secondary treatment helps mitigate nutrient pollution, which is important for preventing algal blooms and maintaining oxygen levels in the river and its estuary.
