Facility Information

Arizona Public Service (APS) has applied for a renewal AZPDES permit for the proposed discharge of up to 19.5 million gallons per day (mgd) of treated domestic effluent from the APS Water Reclamation Supply System (WRSS) Pipeline to the Buckeye Canal, tributary to the Hassayampa River in the Middle Gila River Basin. The pipeline has a total of 21 outfalls located between Township 1N, Range 2W, Section 25 and Township 1S, Range 3W, Section 5 in Maricopa County, Arizona. Discharge typically occurs once every three years when the pipeline needs to be drained for maintenance and inspection activities. Effluent in the pipeline is supplied by wastewater treatment plants operated by the cities of Phoenix, Tolleson, and Goodyear. All plants contributing effluent to the pipeline have AZPDES permits and treat to secondary standards. The permittee operates the pipeline to provide the Palo Verde Nuclear Generating Station with cooling water.
