 Rely upon the Inland Empire Brineline, originally constructed by the Santa Ana Watershed
Authority, and utilize the 15-mile brineline extension constructed by the Yucaipa Valley
Water District.
 Consider achieving a zero-discharge of treated wastewater to provide the ultimate
protection of downstream water resources consistent with the goals of the Clean Water
Act.

STATE OF CALIFORNIA BENEFITS:
 Reduce the need for water to be imported from northern California that would normally be
required to meet future water demands allowing more water to remain in the Sacramento
Delta.
 Implement conservation programs, including efficiency water use and water recycling,
consistent in protecting the water resources of the State of California.

The Yucaipa Valley Regional Water Supply Renewal Project

The Yucaipa Valley Regional Water Supply Renewal Project is an innovative salinity control
project that will effectively eliminate the buildup of minerals in the Yucaipa Valley that would
typically degrade drinking water supplies. The overall project involves expanded reverse osmosis
infrastructure at the Yucaipa Valley Regional Water Filtration Facility (Salinity Concentrate
Reduction and Minimization “SCRAM” System); an expanded reverse osmosis and treatment
infrastructure at the Wochholz Regional Water Recycling Facility (Salinity and Groundwater
Enhancement “SAGE” Project); and a recharge facility at the Calimesa Lake and Spreading
Basins. Coupled with the District’s aggressive recycled water program, these projects will
minimize the amount of water imported from the fragile ecosystem in northern California and allow
for the maximum use of high-purity recycled water.
