Streetman WWTP - Secondary Treatment Plant in Streetman, Texas

Streetman WWTP is a municipal wastewater treatment plant located in Streetman, Texas, a small community in Freestone County. The plant serves a population of 260 residents, reflecting its role as a local facility for a rural area. It is situated near North FM 80 and operates under the regulatory framework of the United States Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level of treatment that removes biodegradable organic matter and suspended solids. With a designed capacity of 302.83 megaliters per year and an actual discharge volume of 132.49 megaliters per year, the plant operates well within its capacity. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into a local water body, likely a creek or river within the Trinity River basin, which ultimately drains into the Gulf of Mexico. The plant's inland location, over 50 km from the coast, reduces direct marine impact. The surrounding watershed supports diverse aquatic life and is part of the larger Trinity River system, which provides habitat for fish and wildlife.

The plant's discharge enters a local watercourse within the Trinity River basin, which flows southeast through Texas and empties into Trinity Bay, part of the Galveston Bay system, and ultimately the Gulf of Mexico. This watershed supports a variety of freshwater and estuarine species, including fish, crustaceans, and migratory birds. The plant's secondary treatment helps protect downstream water quality by reducing organic pollutants and suspended solids before discharge.
