Program Benefits​
The CBP is a direct investment in the Chino Basin that will deliver long-term environmental, economic, and community benefits while there is still time to develop access to critical future water supplies.
Water Reliability
The Chino Basin Program will deliver a new Advanced Water Purification Facility and aquifer replenishing wells that strengthen long-term water reliability for our local communities. Producing up to 15,000 acre-feet of advanced purified recycled water annually for storage in the Chino Groundwater Basin, the AWPF will create a dependable local supply that can be drawn upon during emergencies or extended droughts, reducing reliance on imported water and ensuring greater resilience for the region.
Environmental Benefits
The Chino Basin Program will generate environmental benefits by supporting healthier ecosystems both locally and in Northern California. The program will help maintain flows in Northern California rivers, which are vital for the health of the Bay-Delta ecosystem. In dry years, these flows provide a seasonal boost in the spring that supports native fish populations, especially Chinook salmon.
Timeliness/Cost
The Chino Basin Program received a $215 million conditional funding award from the State’s Prop 1 Water Supply Investment Program (WSIP) in 2018, followed by an additional $53.9 million in 2025 to account for cost-of-living increases and to ensure the project continues forward, a total of $268.9 million.
Making the best use of available funding opportunities now will position the CBP to align with California and federal policy priorities related to disaster mitigation, climate adaptation, and water reliability. Delaying the pursuit of these funds could result in increased funding competition, elevated project costs, and diminished eligibility as future funding cycles and sources change.
Water Quality
As part of IEUA’s expanded regional recycled water program, the Chino Basin Program will provide a reliable new source of high-quality water for the region. Infrastructure improvements including the new Advanced Water Purification Facility, the new Rialto Recycled Water Pipeline, and new Chino Groundwater Basin aquifer replenishing wells and extraction water supply facilities will all play a unique role in generating, storing, and delivering high quality water to Chino Basin communities.
