Sterling Natural Resource Center

About the Project

The Sterling Natural Resource Center (SNRC) will be  a state-of-the-art facility in Highland, California, that will provide a sustainable new water supply to boost the region’s water independence. Capable of treating up to 10 million gallons a day, the SNRC recharges the local Bunker Hill Groundwater Basin and creates new opportunities for the surrounding community in the form of education and training, community space, neighborhood improvements, and new habitat for the Santa Ana Sucker fish. 

Replenishing the Local Water Supply

The facility will transform and enhance the region’s water supply by:

  • Creating a new, local source of water for the community and region
  • By replenishing the Bunker Hill Basin with recycled water, the region will be able to store hundreds of millions of gallons of water for dry years.
  • This effort creates an opportunity to assist with meeting both local water agencies’ needs and environmental commitments.


The SNRC will be constructed on a 14-acre parcel of land located at North Del Rosa Drive between East 5th Street and East 6th Street. The Treatment Facility would be located on the eastern property while the Administration Center would be located on the western parcel. The collection/conveyance pipelines would be constructed along the existing rights of way.

Groundbreaking Celebration

On October 20, 2018, local officials and community members joined East Valley Water District (EVWD) to celebrate the groundbreaking of the Sterling Natural Resource Center (SNRC). Read the official press release here.
