Sterling Natural Resource Center

The Sterling Natural Resource Center (SNRC) is a state-of-the-art facility in San Bernardino, California, that provides a sustainable new water supply to boost the region’s water independence. 

SNRC Administration Center

Up to 8 million gallons a day

Capable of treating up to 8 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:

  • Community Space with Picnic Area and Walking Paths

  • Provide a Drought-Proof Water Supply

  • Provide Street Improvements

  • Educational Training Programs

Location

The SNRC was constructed on a 20-acre parcel of land. The Treatment Facility is located on the eastern property while the Administration Center is located on the western parcel.

Water Recycling

Replenishing the Local Water Supply

The SNRC transforms and enhances the region’s water supply by:

  • Creating a new, local source of water for the community and 600,000 residents in the region.
  • 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.

Maximizing Resources

Co-Digestion Technology

In addition to recycling wastewater, the SNRC will use co-digestion technology to give food waste a new purpose and  maximize this resource to create renewable electricity. There may be a potential to use the material that remains after energy generation to produce fertilizer.

This enhancement represents a significant improvement to the project by allowing the SNRC to produce enough renewable electricity to meet the facility’s energy needs, with additional electricity transferred onto the energy grid.
