Water Supplies in the Sacramento Region

The Sacramento region’s water supplies come from a variety of local sources:

  • Surface water – diverted from local rivers and directly from Folsom Reservoir, under pre- and post-1914 water rights and Central Valley Project water service contracts.
  • Groundwater – from productive aquifers that underlie the valley portion of the Sacramento region.
  • Recycled water – water treated at the region’s waste water treatment plants is increasingly used for landscape irrigation and industrial uses.

Equally important to these water sources are water efficiency and conservation programs, which help ensure supplies continue to meet future needs. The region is also increasingly putting remediated groundwater to beneficial uses.
