Water Testing & Treatment
The United States Environmental Protection Agency and California Department of Public Health set water quality standards and regulations in order to ensure that water districts, like East Valley Water District, continue to provide the highest quality of water to customers.
District staff takes regular samples for water quality and compliance with these standards and regulations. The District has always met these standards. Our laboratory costs for monitoring water quality in 2018 were $95,000. To view our annual testing results, please review our annual Consumer Confidence Reports.

Sterling Natural Resource Center
The Sterling Natural Resource Center (SNRC) will provide a sustainable new water supply to the region by recycling and treating up to 10 million gallons of water per day using technology known as Membrane Bioreactors (MBR). This wastewater treatment process combines ﬁltration with biological treatment to dramatically reduces the amount of space needed to operate the facility and allows for the processes to be completely self-contained.
