As the third dry year in a row, FY 08/09 had many water supply challenges. Along with low rainfall and reduced sierra snowpack, a federal court ruling to curtail pumping from the Sacramento-San Joaquin Bay Delta further restricted the amount of available water. Despite these significant challenges, careful planning and investments in a diverse portfolio of water supply resources helped us meet our water conservation and recycling goals; that is, a reliable water supply for the residents and businesses of the community. Our water use efficiency program is a key part of this portfolio, with nearly 65,000 acre-feet of water savings in FY 2008/09 – roughly enough water to supply 130,000 families in Santa Clara County. Water Conservation is widely considered the most cost-effective option in an available water supply portfolio. Our water conservation program is no different as it relies on a thorough cost-benefit analysis to develop program details and rebate levels. We are proud to report that the district once again received recognition as a statewide leader in water and energy conservation. Out of hundreds applicants, the Santa Clara Valley Water District was one of five organizations, and the only governmental agency, chosen to be honored in the “Best Overall” category from California’s energy efficiency outreach campaign, “Flex Your Power.” Our District helped the community save over 19.5 billion gallons of water through its programs during the last fiscal year (FY 07/08). These programs include technical and financial assistance in the residential, commercial, landscape, and agricultural sectors of Santa Clara County. Using water wisely to meet the needs of the growing community and meet challenges such as the possible continuation of the drought, reduced flow from the Bay Delta and climate change issues, will continue to be a goal of the District in years ahead.
