Your Neighborhood


As a water wholesaler, Zone 7 is wholly committed to working in partnership with our retailers and other regional stakeholders to be an integral part of our neighborhoods throughout the Tri-Valley area. We manage all of our water resources in a holistic, integrated fashion, making informed decisions with collective input from our community.

We participate in a number of school and community sponsorship programs and host events that invite our community to learn more about our work with tours, open houses and more.

Our Water Academy program goes directly into neighborhoods by visiting over 600 classrooms each year, bringing a comprehensive curriculum to educate youth about water resources.

Interactive Trail Maintenance Map

We work hard to maintain the integrity of Tri-Valley’s flood protection system to keep our community safe from flooding. Due to both environmental regulations and weather conditions, most of this construction work is limited to the warm, dry season. Doing this important work safely means occasional impacts to trails are necessary. In order to minimize the impact of trail closures and detours on our community, our staff updated and improved the interactive trail maintenance map so residents can now view, in real-time, the season’s planned, active and completed construction projects. Please note this map does not reflect closures due to immediate weather and storm damage.

Trails and Recreation Facilities in the Zone 7 Service Area

Zone 7 recognizes the benefits of public access along flood control channels. We collaborate with cities and local park districts to incorporate our maintenance roads into pedestrian and bicycle trail networks. Cities and parks districts are responsible for maintaining the trails that are located on Zone 7 property. Today, there are more than 19 miles of trails along Zone 7-owned channels that provide off-street connections to local and regional parks and recreation facilities.

New Monitoring Well at Ken Mercer Sports Park

In a continuing effort to supply the Tri-Valley with safe, reliable water that surpasses state and federal drinking water standards, Zone 7 is installing an additional monitoring well to serve as an early detection system for Per- and Polyfluoroalkyl substances (PFAS) for the neighboring water supply wells in the area.


Stoneridge Well PFAS Treatment System Project

In a continuing effort to supply the Tri-Valley with safe, reliable water that surpasses state and federal drinking water standards, Zone 7 is in the final stages of constructing a water treatment system to address Per- and Polyfluoroalkyl substances (PFAS) found in the local groundwater at the Stoneridge Well. The treatment system went online in September 2023 and final construction at the facility is anticipated to be complete by Spring 2024.
