Demi John Area WWTP is a projected wastewater treatment facility located in Key Largo, Texas, United States. The plant is designed to serve a population of 1,610 and has a designed capacity of 264.98 thousand cubic meters per year, with an advanced treatment level. The plant operates under the U.S. Clean Water Act, which requires NPDES permits for discharges into surface waters. As an advanced treatment facility, it goes beyond secondary treatment to remove additional nutrients and contaminants, which is particularly important for coastal areas to protect sensitive marine ecosystems. The plant's discharge volume of 264.98 thousand cubic meters per year enters the local watershed, which ultimately drains into the Gulf of Mexico. The coastal location means the treated effluent must meet stringent standards to prevent eutrophication and protect aquatic life in the nearshore environment.
Environmental context
The plant is located within 10 km of the Gulf of Mexico coast in Brazoria County, Texas. The treated wastewater discharges into local waterways that flow into the Gulf, a large marine ecosystem supporting diverse fish, shellfish, and migratory birds. The advanced treatment level helps reduce nutrient loading, which is critical for preventing algal blooms and maintaining water quality in the Gulf's estuaries and coastal zones.
