Overview
Padre Dam imports 100% of our drinking water supply from the San Diego County Water Authority (SDCWA).
How Our Water Is Imported
Our water supply depends on a 1922 agreement between seven western states as well as infrastructure (i.e. aqueducts, pipelines) operated by federal, state and regional agencies. The water Padre Dam imports comes from the State Water Project and the Colorado River Aqueduct. Water travels through over 600 miles of aqueducts and 1,100 miles of pipeline to get to San Diego County.
Padre Dam has a large infrastructure of its own to provide water to your home, including over 300 miles of water mains - enough pipe to stretch from San Diego to Phoenix.
