How much treatment has reclaimed water received?
The reclaimed water from the 91st Avenue Wastewater Treatment Plant (WWTP) meets all applicable water quality standards. SROG’s reclaimed water systems provides several contaminant barriers. The Cities operate an extensive industrial pre-treatment program to remove toxics and metals before raw industrial sewage is discharged to the sewer. The sewage, which is a combination of pre-treated industrial wastewater and commercial/residential wastewater, undergoes a significant amount of treatment at the WWTP. The WWTP is equipped with state-of-the-art treatment processes that remove the organic and nitrogenous compounds that are the main components of raw sewage. The City of Phoenix, as the operator of the 91st Avenue WWTP monitors the water quality from the WWTP on a daily and weekly basis for nearly 200 chemicals. The water is essentially safe for non-potable reuse.
