The North Bay Water Reuse Program (NBWRP) is a coordinated effort of three counties and 10 water and sanitation agencies, working together as one entity, to address water supply shortages from a watershed perspective. The Program’s member agencies are investing in a number of diverse recycled water projects to offset potable demands throughout the North Bay region. 

From its inception the NBWRP has used a multiple-benefit approach to recycled water supply planning and has applied this from a watershed and sub-regional perspective PDF

This programmatic approach to developing recycled water yields supply benefits in two fundamental ways; as projects come on-line they reflect the priorities and community needs of each agency, while concurrently, and incrementally, contributing toward water supply reliability for the region.

The North Bay counties of Sonoma, Napa and Marin face long-term water supply challenges. Existing surface and groundwater supplies are stretched to their limits and some groundwater basins are over-pumped. By providing a reliable recycled water supply to offset limited potable water, we are able to serve the region’s diverse needs and help maintain the area’s high quality of life.

From its inception the NBWRP has used a multiple-benefit approach to recycled water supply planning and has applied this from a watershed and sub-regional perspective. We’ve planned for treatment, storage and distribution projects to meet the broadest possible end-user needs and in doing so have yielded significant value for the region’s infrastructure investment.  Examples of these multiple- benefits include:

  • Traditional community landscape applications,
  • Year-round agricultural water supply,
  • Support and management of groundwater basins,
  • Riparian, wetland, waterfowl, aquatic species, other habitat and environmental benefits and,
  • Community recreation and open space amenities.

The NBWRP has two phases.  Phase 1 has been under construction for five years and is comprised of $104 million in projects.  It is at 65% completion and includes foundational infrastructure for treatment, storage and distribution.  Phase 1 projects deliver high-quality water for parks and landscaping, premium wine grape production and restoration of tidal wetlands and wildlife habitat.

Phase 2 is in the planning stage and is estimated at $150 million in projects.  These projects will build on Phase 1 infrastructure by increasing storage and distribution, groundwater management, environmental and community benefit projects – all by providing high-quality recycled water throughout the North Bay region. 

Recycled Water Storage PondWhen fully implemented, Phase 1 and 2 will yield 33,000 AFY of recycled water and these projects will maximize regional-scale reuse to build long-term resiliency into the region’s water supply.  By working from a watershed perspective to develop recycled water as new supply, the NBWRP serves as a model for how communities can work together to plan for self-sufficiency and in turn, gain supply reliability using recycled water to yield a variety of benefits.
