This formula, together with the actual <br />amount of water deliveries to the City, determines the amount that the City pays under the <br />Master Water Sales Contract. The City anticipates that its cost of acquiring water from San <br />Francisco will increase in the future as San Francisco continues to implement its capital <br />improvement plan for the Hetch Water System and the resulting costs of operating the Hetch <br />Hetchy system continue to increase. See "RISK FACTORS - Wholesale Water Costs." <br /> <br />Water Conservation Program <br /> <br />In order to address the Enterprise's water supply concerns, the City has developed an <br />extensive water conservation program. This conservation program includes several of the Best <br />Management Practices developed by the California Urban Water Conservation Council <br />(www.cuwcc.org). The City projects that this conservation program will reduce water use by <br />customers of the Enterprise by 637 acre feet per year by 2010. <br /> <br />Water Storage and Distribution System <br /> <br />General. The Enterprise's distribution system consists of distribution mains, 12 storage <br />facilities, ten pump stations, and 26 pressure reducing valves ranging from two to six inches in <br />diameter. <br /> <br />Water Storage Facilities. The Enterprise's 12 storage facilities range in size from 0.09 <br />million gallons to 4.00 million gallons with a total storage capacity of 21.24 million gallons. <br />Typically, the storage tanks are filled to 50% of capacity, which would provide two days' supply <br />to the customers of the Enterprise in an emergency situation. <br /> <br />22 <br />
