7.0 Conservation Goals Given that the City does not have any pressing infrastructure or raw water supply shortages that might require immediate aggressive water conservation activities, the goals and objectives for future water conservation measures and programs set by the City have been developed to help address future community sustainability and regional water supply reliability. The City has always been a good steward of the community, the region and the environment, and those policies that the City has established and implemented in the past will be further strengthened by additional, meaningful water conservation. To this end, the City is looking to reduce customer and City raw water demands by approximately 10 percent by buildout, for an expected reduction of about 3,500 acre -feet. Given that this Plan focuses on only those measures and programs that will be implemented in the next ten years, from 2008 to 2017, the amount of raw water demand reduction estimated over the next ten -year period is approximately 1,600 acre -feet, or 7.7 percent of the 2017 forecasted total raw water demand. Additional water savings are expected as the City expands and enhances its reuse program; however, specific details regarding how return flow will be captured and put to beneficial use are beyond the scope of this document. The water savings expected from the water conservation measures and programs identified in this plan have an estimated value of approximately $27 million in 2008 dollars, based on a treated water development cost of $15,000 per acre - foot. The future cost of water includes the combined cost of new raw water supply, estimated to be $10,000 per acre -foot, plus system costs for collection, treatment and distribution, estimated to be $5,000 per acre -foot. It is possible that the future cost of water maybe substantially higher than what has been used in this exercise. 35
