The United States Environmental Protection Agency (EPA) and the Texas Commission on Environmental Quality (TCEQ) issue permits that require discharges of treated wastewater to meet certain standards in accordance with the Clean Water Act. To meet these high standards, El Paso Water Utilities is committed to providing the best available technology and most cost effective treatment processes to ensure proper and sufficient treatment of wastewater collected from the city. All wastewater treatment plant operators are required by the TCEQ to obtain and maintain varying degrees of certification. They are required to have knowledge of plant operations, treatment, design, and federal and state rules and regulations.
