Water is one of our most precious resources. Many California cities and water districts struggle to obtain sufficient water to sustain their growing populations and economies. Whether in time of plenty or drought, cities and water districts state-wide face a never-ending challenge to acquire, treat, and distribute water to customers. American Canyon is no exception. The main source for our water supply is the State Water Project through the North Bay Aqueduct. During the peak irrigation season, we supplement our supply as needed with treated water from the cities of Napa and Vallejo.

The City operates a Water Treatment Plant near Highway 12 (Jameson Canyon Road) to produce drinking water that meets the highest quality standards set by state and federal regulations. There are two treatment processes at the Plant: a conventional sedimentation and filtration treatment process, and a second, state-of-the-art membrane filtration process. Together the two processes produce up to 5.5 million gallons of potable water each day for residents and businesses in our water service area, which extends from the Napa/Solano County line to Soscol Creek just north of the Napa Airport.

In 2017, the City became a partner in the Sites Reservoir Project, an environmentally beneficial, off-river reservoir that will capture excess water from major storms and save it for drier periods. This Project will help California’s farms, businesses, and cities continue to supply reliable water when other sources are low. Anticipated construction will begin in 2022. Visit for updates.
