Chocolate Bayou WWTP - Harris County, Texas Wastewater Treatment Plant

Chocolate Bayou WWTP is a municipal wastewater treatment facility located in Harris County, Texas, serving a population of around 29,000 people. The plant is situated in the Almeda area, part of the greater Houston metropolitan region, and plays a key role in managing local wastewater. As a facility in the United States, the plant operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Texas Commission on Environmental Quality (TCEQ). For a population of this scale, secondary treatment is typically required, and the plant's designed capacity is 1.00 million gallons per day, indicating it is sized to handle the community's wastewater flows. The plant's treated effluent is discharged into local waterways that ultimately drain into the Gulf of Mexico via the Brazos River or Galveston Bay system. This discharge supports downstream aquatic ecosystems and must meet strict water quality standards to protect sensitive coastal environments.

The plant's discharge enters the Brazos River basin, which flows southeast into the Gulf of Mexico. This coastal region supports diverse estuarine habitats, including marshes and bays that are critical for fish and bird species. The Gulf of Mexico receives nutrient and pollutant loads from numerous sources, making proper treatment essential to prevent eutrophication and protect marine life.
