Where does the
Tri-Valley’s water come from?

Learn about the world travels of our water supply

The water we have in the world today is the same water that has sustained all life on this planet since the beginning of time. Mother Nature’s water cycle does an amazing job of purifying our water and we give her a little help to transport it to where we need it! Learn about the sources of our water supply with the resources below.

Surface water: travels around the world


The majority of the Tri-Valley’s water supply is imported surface water. Follow along on our water’s journey through the Feather River Watershed.

Dig below the surface: learn about our groundwater reserves


Approximately 10% of the Tri-Valley’s water comes from under this world. Our “reserve” water supply is located beneath our feet in a groundwater basin. Sands and gravel deposited thousands of years ago provide just enough space for water to gather underground. We are lucky enough to have (and need to sustainably manage!) the Livermore Valley Groundwater Basin.

The Value of Water


Appreciating the value of water means understanding what it is worth! Learn more about the role water plays in our community and our economy. Both treated and untreated water delivered to the Tri-Valley has far reaching benefits for our region. The treated water we use in our home and businesses keep us all healthy and happy! Did you know local vineyards use untreated water for irrigation, helping to fuel a $200 million-per-year industry? Additionally, golf courses use untreated or recycled water to maintain their grounds, part of a booming tourism industry.
