WATER CONSERVATION PLAN 2008 The overall cost to implement this plan is estimated to be about $3.3 million over the next ten years with about $1.4 million for incentives and rebates, education and training, audits and related measures and programs, and monitoring and verification activities. The remaining balance will be used for ordinance inspections and enforcement, raw water conversion and improvement projects, meter testing and replacement, and water rate assessments and implementation efforts. For the City to obtain a similar amount of replacement water to meet this supply (i.e., 1,600 acre - feet), it would cost approximately $27 million.3 As discussed in the next section, it is anticipated that the City would pursue approximately $100,000 over the next four years from the State grant program to initiate some of the most important components of this plan. The grant requests will focus upon providing audits, education and rebates to the City's commercial and irrigation customers, but will include some programs that support residential water savings, as well. 30,000 25,000 20,000 15,000 10,000 5,000 Total Raw Water Demand (acre -feet) With and Without Conservation Programs - - - - """' "' ' " Lv I I zu-I L 2013 2014 2015 2016 2017 ❑ Total Raw Water Demand (current and proposed conservation) • Total Raw Water Demand (current conservation) • Total Raw Water Demand (without current or proposed conservation) FIGURE 7 Estimated Total Water Demand With and Without Proposed Water Conservation Program 3 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. 54
