Existing Facilities

East Branch Extension. The East Branch Extension, or EBX, is the portion of the State Water Project that conveys water to the Pass area. It begins at the Devil Canyon Power Plant in San Bernardino and ends on Noble Street just south of Orchard Street in Cherry Valley. The California Department of Water Resources decided to add the EBX to the State Water Project in the 1990’s. The project was a partnership between the Department of Water Resources (DWR), the San Bernardino Valley Municipal Water District, (Valley District), and the Agency. Construction of Phase 1 was completed in 2003. Phase II was completed in 2017.

The EBX is operated by the Agency and Valley District under an agreement with the Department of Water Resources. Click here to view EBX Contract.

Recently Completed Facilities

East Branch Extension Phase 2. Phase 2 of the East Branch Extension, the series of pipes, pump stations, and reservoirs that convey water to the Pass from our delivery point, Devil Canyon Power Plant in the City of San Bernardino, was designed to allow the Agency to import its full allotment of 17,300 acre-feet of water in a year. The project consists of six miles of 66-inch pipe under the Santa Ana River and through Mentone to Yucaipa, the new Citrus Pump Station and Reservoir in Mentone, and additional pumps for the Crafton Hills and Cherry Valley Pump Stations.

Beaumont Avenue Recharge Facility. The Beaumont Avenue Recharge Facility is a new groundwater recharge facility that will enable the Agency to import more water in wet years when it is available and to store it in the local groundwater basin. By adding the ability to store more water in local aquifers, the facility will help to drought-proof the region. Storage is one of the keys to surviving droughts. The facility, located at the southwest corner of Brookside and Beaumont Avenue in Beaumont, consists of five large ponds, a pipeline connecting the ponds to the East Branch Extension under Orchard Street, and a new connection to the East Branch Extension.
