Inland Empire Agencies Partner to Improve Water Supply

 

Three Inland Empire water agencies have partnered with San Bernardino Valley Municipal Water District (SBVMWD) to minimize the amount of water imported from the State Water Project and other sources by capturing and storing more rainfall. Although Inland Empire water agencies rely on local rainfall for roughly 75% of their water supply, a lot of water still flows into the ocean each year forcing the region’s water agencies to purchase remaining supplies.

“Capturing more of our local stormwater is good water management,” said Bob Tincher, SBVMWD’s deputy general manager for resources. “We are continually looking for new water supplies to help us make it through extended droughts like the one we are in now.”

SBVMWD has partnered with Western Municipal Water District (WMWD), San Bernardino Valley Water Conservation District and Riverside Public Utilities on the first phase of new stormwater capture facilities. The four water agencies are developing the capability to capture and store more water, about twice the historical amount, to help the region brace for extended droughts, like the current one that is in its 20th year.

“When completed, these facilities will divert as much as 250,000 gallons of water every minute, up to 80,000 acre-feet of stormwater in a single year—enough for 80,000 families,” said T. Milford Harrison, SBVMWD’s president.

The multiple phases of the project will begin with the Enhanced Recharge Project, which will include water intake improvements and the construction of a 700-foot-long by 140-foot-wide sedimentation basin just downstream from Seven Oaks Dam, near Redlands in San Bernardino County.

When completed, the massive basin will be connected to a pipeline constructed by the water agencies to transport the sediment-free water to existing recharge basins and, eventually, to the Foothill Pipeline near Highland. The final step will be delivering the water to recharge basins throughout the San Bernardino Valley.

Future phases of the Enhanced Recharge Project are expected to begin in 2020. Lastly, additional improvements to the Cuttle Weir and its intake structure to make the entire diversion system more robust, especially during high water flows, will follow.
