Welcome to the Sterling Natural Resource Center Project, a proposed wastewater treatment facility in the City of Highland by the San Bernardino Valley Municipal Water District to treat wastewater generated within East Valley Water District’s service area.

The New Facility

The new treatment facility would produce disinfected tertiary recycled water (Title 22 water quality for unrestricted use). The treated water would be discharged to basins at the new treatment plant site, to existing basins currently operated by the City of Redlands, to City Creek, or to alternative locations.

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 would 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.
