Ten Mile Creek WWTP is a municipal wastewater treatment facility located in Patrick, Texas, within Dallas County. The plant serves a population of approximately 163,500, classifying it as a large agglomeration under U. S. regulatory frameworks. Its location in the Trinity River basin places it within a region that supports diverse aquatic ecosystems and downstream water uses. As a U. S. facility, Ten Mile Creek WWTP operates under the Clean Water Act, administered by the EPA and the Texas Commission on Environmental Quality (TCEQ). Plants of this scale typically require secondary treatment as a minimum, with nutrient removal standards in sensitive watersheds. The facility's discharge is subject to National Pollutant Discharge Elimination System (NPDES) permits, which set limits on pollutants to protect water quality. The treated effluent from Ten Mile Creek WWTP ultimately flows into the Trinity River, which drains into Trinity Bay and the Gulf of Mexico. This watershed supports critical habitats for fish and wildlife, including migratory birds and estuarine species. The plant's operations play a key role in maintaining water quality in the region, particularly given the urban and industrial pressures in the Dallas-Fort Worth metroplex.

Ten Mile Creek WWTP discharges into the Trinity River basin, which flows through north Texas into Trinity Bay and the Gulf of Mexico. The Trinity River supports diverse aquatic life, including several fish species and migratory waterfowl. Downstream, Trinity Bay is an ecologically sensitive estuary that provides nursery habitat for shrimp, crabs, and finfish, making nutrient and pollutant control critical for ecosystem health.
