The plant's discharge enters the local watershed in the Texas Coastal Plain, a region characterized by slow-moving rivers and estuaries that drain into the Gulf of Mexico. The receiving waters support diverse aquatic species and are important for migratory birds. The secondary treatment process reduces nutrient loads, helping to prevent eutrophication in downstream bays and estuaries.
