Inland Empire Utilities Agency Chino Basin Program (CBP)

Inland Empire Utilities Agency Chino Basin Program (CBP)

The CBP was submitted for Proposition 1 – WSIP funding and was awarded $206.9M in conditional funding in July 2018. Under the WSIP, the CBP is proposed to be a 25-year conjunctive use project that proposes to use advanced water purification to treat and store up to 15,000 acre-feet per year (AFY) of recycled water in the Chino Basin and would extract the water during “call” years, which will likely be in dry seasons. The proposed CBP is uniquely designed to deliver public benefits including a highly reliable, dedicated environmental water supply to benefit Bay-Delta instream flows, as well as enhance water supply reliability and improve water quality for water users in Southern California. The CBP would increase additional available groundwater supplies in the adjudicated Chino Basin through increased water recycling that would result from operation of a new advanced water purification facility (AWPF) and through groundwater storage by operation of new injection wells. The CBP would then dedicate a commensurate amount of water generated by the AWPF for Chino Basin use to provide for an exchange of State Water Project supplies in Lake Oroville in northern California that would otherwise be delivered to southern California. The additional Lake Oroville water would subsequently be released in the form of pulse flows in the Feather River to improve habitat conditions for native salmonids and achieve environmental benefits (refer to the Exhibit below). IEUA’s partner and the State Water Project Contractor that will facilitate the exchange for the CBP is Metropolitan Water District of Southern California (Metropolitan).
