ALBA STP - Secondary Wastewater Treatment Plant in Wood County, Texas

ALBA STP is a municipal wastewater treatment plant located in Wood County, Texas, serving a population of 670. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring that effluent meets basic quality standards before discharge. With a designed capacity of 302.83 units and an average daily discharge of 208.20 units, the plant operates below its maximum capacity. As a US facility, it falls under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits, which set limits on pollutants to protect water quality. The plant discharges into a local water body that ultimately drains into the Sabine River basin, which flows into the Gulf of Mexico. This watershed supports diverse aquatic life and provides habitat for fish and wildlife, making proper treatment essential for downstream ecosystem health.

The plant's treated effluent enters a local tributary within the Sabine River basin, which flows southeast through Texas and Louisiana before emptying into the Gulf of Mexico. The Sabine River and its associated wetlands provide critical habitat for fish, migratory birds, and other aquatic species. Maintaining secondary treatment standards helps protect water quality in this ecologically sensitive watershed.
