Andrews WWTP - Municipal Wastewater Treatment in Andrews, Texas

Andrews WWTP is a municipal wastewater treatment facility located in Andrews, Texas, serving a population of about 9,600. The plant is situated in the Permian Basin region, an area known for its oil and gas industry, which influences local water management needs. As a facility in the United States, it operates under the regulatory framework of the Clean Water Act, administered by the Texas Commission on Environmental Quality (TCEQ). For a plant serving a community of this size, secondary treatment is typically required under the Clean Water Act, with possible additional nutrient removal depending on the receiving water body's sensitivity. The plant's capacity and treatment processes are designed to meet state-issued NPDES permit conditions, which set limits on effluent quality to protect public health and the environment. The treated effluent from Andrews WWTP is discharged into local waterways that eventually drain into the Colorado River basin, which flows through Texas to the Gulf of Mexico. The plant plays a key role in protecting the region's water resources, supporting aquatic life and downstream water quality in a semi-arid environment where water conservation is critical.

The plant's discharge enters local tributaries that flow into the Colorado River, which ultimately reaches the Gulf of Mexico. The Permian Basin region experiences low rainfall and high evaporation rates, making water quality management essential for sustaining aquatic habitats and agricultural uses. The Colorado River supports diverse fish species and provides water for irrigation and municipal supply downstream.
