Sustainable Groundwater Management

Placer County is part of the West Placer Groundwater Sustainability Agency, a multi-agency group formed to monitor and manage the local groundwater basin in accordance with the Sustainable Groundwater Management Act.

Placer County, along with the cities of Roseville and Lincoln, and Placer County Water Agency, and in participation with the California American Water Company, adopted a Groundwater Sustainability Plan in 2022. The plan is a long-range planning document aimed at preservation and enhancement of portions of the North American groundwater basin (NASb). The plan outlines evaluation criteria, projects, and management actions to ensure continued health of the basin for continued use by our communities, agriculture, and the environment.

Visit the West Placer Groundwater Sustainability Agency website for more information. The adopted plan can be accessed at: North American Subbasin.

Make Water Conservation a Way of Life

On March 28th, 2022, Governor Newsom signed an Executive Order proclaiming continuing drought conditions. The order calls on all Californians to strive to limit their summertime water use and to use water more efficiently, reducing water use by at least 15% from 2020 levels, in order to help conserve available water supplies. 

Water conservation tips:


  • Install water efficient showerheads and take shorter showers.
  • Run full loads in the dishwasher and washing machine.
  • Turn off the tap when shaving, brushing your teeth, and washing your hands. 


  • Spread mulch in landscaping beds to retain soil moisture. 
  • Reduce landscape irrigation.
  • Prevent irrigation runoff.
  • Water in the morning to reduce water evaporation.
  • Find and fix leaks.
  • Don’t hose off driveways or sidewalks; use a broom.
  • Use a shut-off nozzle on hose ends.

 More tips and resources on water conservation can be found on Save Our Water, or visit California’s drought site for information on current conditions and the State’s response. Mulch is available for purchase at the WPWMA facility – made from green waste diverted from the landfill to reduce greenhouse gas emissions.
