ABOUT PASO ROBLES WATER

Water Sources

Currently, the City of Paso Robles relies on a combination of surface water supplies and groundwater to provide potable water to our water customers. In a normal year, over fifty percent of the City’s water is supplied by seven relatively-shallow wells located along the Salinas River corridor. Surface water from the Nacimiento Water Project and groundwater from the Paso Robles Groundwater Basin is used to supplement the Salinas River wells.

The City is a participant in the Lake Nacimiento Water Project and has secured a 6,488 acre-feet per year water entitlement. The water connection fees and water rates provided the funds needed to construct, operate and maintain the City's surface-water treatment plant. In addition to the water treatment plant, connection fees and water rates provide for the ongoing operations and maintenance of all City water infrastructure.

The use of Lake Nacimiento water allows the City to reduce its dependency on the Paso Robles Groundwater Basin, and provide a reliable long-term water supply for the City. The City’s historical and projected water supplies are shown in the chart below.

The City's Urban Water Management Plan documents the City’s sources of water supply, defines water demands, presents a water shortage contingency plan, describes implementation of water demand management measures and guides conservation efforts.
