The Del Valle Water Treatment Ozonation Project is now online and actively serving the Tri Valley community! The Ozonation Project is the latest investment by Zone 7 in providing high-quality water that meets the rigorous Zone 7 standard. The Del Valle Water Treatment Plant, which has been serving us well since it was built in the 1970s, was upgraded and expanded to add raw water ozonation to the plant’s existing treatment process. The Ozonation Project brings best-in-class technology for disinfection to our water treatment, and represents a capital investment of $49 million, funded by bonds. As part of our commitment to high-quality water, Zone 7 is investing in ozone treatment because it is the best alternative to chlorine. Take a behind-the-scenes look at the new facility in our grand opening video.

We are committed to delivering a safe and reliable water supply to our customers. Zone 7 started proactively monitoring for PFAS in 2013 and has been following the State Water Resources Control Board's quarterly monitoring Order since January 2019. The results from monitoring are updated each quarter and can be found here. While some wells have shown levels of PFAS above the recommended Response Levels (RLs), we follow approved treatment methods to ensure that all water delivered to our customers is below the RL. 

We will continue to closely monitor the quality of our community’s drinking water supplies, utilizing proven technologies and best practices to ensure that any emerging PFAS issues are managed in a transparent and responsible manner.

Preliminary Lake Use Evaluation for the Chain of Lakes (2014)

The purposes of this 2014 study are to identify which potential lake uses may be more suitable for individual former quarries – especially where conflicting proposed alternatives uses may exist – and provide a framework for evaluating proposed uses as lakes are transferred to Zone 7 ownership. The evaluation generally does not preclude any given lake from distinct uses, but instead provides a tool for examining the benefits or impacts associated with a proposed use.
