All the water we rely on in the world today has been here since the birth of our planet. Water has cycled and circulated through distance and time to continually nourish the Earth with the liquid gold that sustains all life. The Tri-Valley Water Partners are charged with ensuring water continues to flow on this elaborate journey over hundreds of miles to get to the Tri-Valley community.
Discover the intricate process that transports water through the wonders of the world and into your tap, along with the challenges our water system is facing and the potential solutions the Tri-Valley Water Partners are exploring to keep our water flowing.

Journey through the Wondrous World of Water
Currently, the Tri-Valley area imports about 70% of the water we use from outside our region. How in the world does water get from the snow packed peaks of the Northern Sierra Nevada to the homes and businesses of the Tri-Valley community? Through 237 miles of naturally occurring waterways and built infrastructure, our water comes to the Tri-Valley via an intricate interconnected system of rivers and reservoirs, dams and aqueducts.

Challenges to our Water Supply System
The Tri-Valley is heavily reliant on imported water through California’s State Water Project, due to historic over pumping of the local groundwater basin. In the early 1960s, Zone 7 partnered with the State of California to receive imported water to help manage the local groundwater basin and provide critical drinking water supply. This impacts the cost of delivering our water, and leaves us vulnerable to long term reliability concerns. Our current system provides us with limited local control with so much of our water coming from outside the region.

Potential Water Reliability Solutions
We will need to implement a diverse range of strategies to mitigate the threats to our water system, and eventually increase reliability by offsetting our reliance on imported water that comes to us from the Delta though a single source - the South Bay Aqueduct. The Tri-Valley Water Partners are proactively examining these challenges to find long-term solutions. Learn more about how in the world we will secure our water for the future of the Tri-Valley.
