Lakeview Regional WWTP - Lewisville, Texas Wastewater Treatment Plant

Lakeview Regional WWTP is a municipal wastewater treatment facility located in Lewisville, Denton County, Texas. It serves a population of about 40,604 people, placing it in the medium-agglomeration category for US regulatory purposes. The plant is situated inland, more than 50 kilometers from the coast. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Texas Commission on Environmental Quality (TCEQ). For a plant serving this population size, secondary treatment is typically required, with potential additional nutrient removal if discharging to sensitive waters. The plant's treated effluent likely discharges into a local waterway that drains into the Trinity River basin, ultimately reaching the Gulf of Mexico. The Trinity River supports diverse aquatic life and provides water for municipal and agricultural use downstream.

The plant's discharge enters the Trinity River watershed, which flows southeast through Texas into Trinity Bay and the Gulf of Mexico. This river system supports important fish and wildlife habitats, including migratory bird corridors. The Gulf of Mexico receives nutrient loads from multiple sources, making effective wastewater treatment critical to reducing hypoxia in coastal waters.
