This formula, together with the actual amount of <br /> water deliveries to the City, determines the amount that the City pays under the Water Supply <br /> Agreement. The City anticipates that its cost of acquiring water from San Francisco will increase <br /> in the future as the SFPUC continues to implement the WISP. See "RISK FACTORS—Wholesale <br /> Water Costs." <br /> Water Conservation Program <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 239 AFY by 2020. <br /> Water Storage and Distribution System <br /> General. The Enterprise's distribution system consists of distribution mains, 12 storage <br /> facilities, 10 pump stations, and 26 pressure reducing valves ranging from 2 to 6 inches in <br /> diameter. <br /> Water Storage Facilities.
