How We Serve You

Water Quality

Our water meets not only state and federal health standards, it outperforms many of them – which inspired us to create the more stringent Zone 7 standards.

Water Reliability

We are continually working to secure our water supply – even in our ever-changing environment of water rights and availability.

Flood Protection

We are continuously improving our level of preparedness and resiliency in managing our watershed to protect the Tri Valley community from flooding.
