Chapter 4 <br />Water Use Characterization <br />THE CITY OF <br />PLEASANTON, <br />• Institutional (and Governmental): A water user dedicated to public service. This type of <br />user includes, among other users, higher education institutions, schools, courts, churches, <br />hospitals, government facilities, and nonprofit research institutions (CWC 10608.12(i)). <br />• Landscape: Water connections supplying water solely for landscape irrigation. Such <br />landscapes may be associated with multi -family, commercial, industrial, or <br />institutional/governmental sites but are considered a separate water use sector if the <br />connection is solely for landscape irrigation. <br />• Sales to Other Agencies': Water sales made to another agency. Projected sales may be <br />based on projected water demand provided by the receiving agency. There is inherent <br />uncertainty in future demand projections, therefore, any projected sales reported in the <br />UWMP are for planning purposes only and are not considered a commitment on the part of <br />the seller. <br />• Groundwater Recharge: The managed and intentional replenishment of natural <br />groundwater supplies using man-made conveyances such as filtration basins or injection <br />wells. This includes water used for groundwater banking or storage. <br />• Saline Water Intrusion Barriers: Injection of water into a freshwater aquifer to prevent the <br />intrusion of saltwater. <br />• Agricultural: Water used for commercial agricultural irrigation. <br />• Other: Any other water demand that is not adequately described by the water sectors <br />defined above. <br />• Distribution System Losses: The difference between the actual volume of water treated and <br />delivered into the distribution system and the actual metered consumption. <br />4.2.1 Historical Water Use <br />The City's past water use among water use sectors is reported in Table 4-1.
