LORAINE STP - Secondary Wastewater Treatment in Mitchell County, Texas

LORAINE STP is a municipal wastewater treatment facility located on County Road 448 in Mitchell County, Texas, serving a population of 760. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring removal of organic matter and suspended solids before discharge. The plant operates under the US Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all point source discharges. For a facility of this scale, secondary treatment is the minimum requirement, and the plant's discharge volume of approximately 265,000 gallons per day is consistent with its design capacity of about 189,000 gallons per day. The treated effluent from LORAINE STP is discharged into local streams that eventually flow into the Colorado River basin, which drains to the Gulf of Mexico. The plant plays a key role in protecting water quality in this semi-arid region of West Texas, where water resources are critical for agriculture and ecosystems.

LORAINE STP discharges into tributaries of the Colorado River in Texas, which flows southeast to Matagorda Bay and the Gulf of Mexico. The receiving waters support aquatic life and are part of a watershed that provides irrigation and drinking water. The plant's secondary treatment helps reduce nutrient and organic loading, protecting downstream water quality in a region where water scarcity and quality are significant concerns.
