Oglesby WWTP - Secondary Wastewater Treatment Plant in Oglesby, Texas

Oglesby WWTP is a municipal wastewater treatment plant located in Oglesby, Texas, a small community in Coryell County. The facility serves approximately 500 residents, reflecting its role as a small-scale treatment operation within the state's wastewater infrastructure. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. Under the National Pollutant Discharge Elimination System (NPDES), plants of this size are typically permitted by the Texas Commission on Environmental Quality (TCEQ). The designed capacity of 215.77 million gallons per year indicates the plant's ability to handle peak flows, while the actual discharge volume of 98.42 million gallons suggests operational headroom. The treated effluent is discharged into a local waterway, likely a tributary of the Brazos River basin, which flows into the Gulf of Mexico. As a small inland plant, its environmental impact is localized, contributing to the protection of downstream aquatic habitats and water quality in the region.

The plant discharges into a local watercourse within the Brazos River basin, which ultimately drains into the Gulf of Mexico. The Brazos River supports diverse aquatic life and is an important water resource for Texas. Downstream ecosystems include riparian habitats and estuarine zones near the coast, where nutrient loading from upstream sources can affect water quality. The plant's secondary treatment helps reduce organic pollutants and suspended solids, mitigating potential impacts on the receiving water body.
