Vanderbilt WWTP - Secondary Treatment Facility in Vanderbilt, Texas

Vanderbilt WWTP is a municipal wastewater treatment plant located in Vanderbilt, Jackson County, Texas. The facility serves a small population of 320 residents, providing secondary treatment to meet state and federal water quality standards. Its designed capacity is 215.77 megaliters, with an annual discharge volume of 189.27 megaliters. The plant operates under the regulatory framework of the US Clean Water Act, administered by the Texas Commission on Environmental Quality (TCEQ). As a secondary treatment facility, it uses biological processes to remove organic matter and suspended solids. For a plant of this small scale, secondary treatment is typical and meets the requirements for protecting local water quality. The treated effluent is discharged into a local waterway that drains into the Lavaca River basin, eventually reaching the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems, including estuarine habitats along the Texas coast that support diverse marine life and migratory bird populations.

The plant's discharge enters a tributary of the Lavaca River, which flows into Lavaca Bay and then the Gulf of Mexico. This coastal watershed supports ecologically sensitive estuarine habitats, including seagrass beds and oyster reefs, which are important for fish and bird species. The secondary treatment helps reduce nutrient and pollutant loads to these downstream environments.
