Final Report, 2010 Urban Water Management Plan - Culver City

3.4 Sales to Other AgenciesThere are no anticipated sales to other agencies for the Culver City System; therefore,Table 3-12 has intentionally been left blank.Table 3-12:Sales to Other Agencies in ac-ft/yrWater Distributed 2005 (2) 2010 2015 2020 2025 2030 2035N/A N/A N/A N/A N/A N/A N/A N/ANotes:1. This table is based on the DWR Guidebook Table 9.2. Based on calendar year.3.5 Other Water Uses and System LossesIn order to estimate total water demand, other water uses, as well as any water lost duringconveyance, must be added to the customer demand. California regulation requires watersuppliers to quantify any additional water uses not included as a part of water use by customertype. There are no other water uses in addition to those already reported in the Culver CitySystem.System losses must be incorporated when projecting total water demand. System losses (alsoknown as non-revenue water) are defined as the difference between annual water productionand annual sales. Included are system losses due to leaks, reservoir overflows, or inaccuratemeters, and other water used in operations such as system flushing and filter backwashing.GSWC does not tabulate system losses separately from other water uses; such as operations.In the Culver City System, from 1994 through 2010, system water losses have averaged 6.4percent of the total production; therefore, this rate was incorporated into water projections.Table 3-13 provides a summary of projected system losses in the Culver City System.Table 3-13:Additional Water Uses and Losses in ac-ft/yrWater-Use Type 2005 (2) 2010 2015 2020 2025 2030 2035Other Water Uses N/A N/A N/A N/A N/A N/A N/ASystem Losses (3) 548 430 399 404 409 414 419Total 548 430 399 404 409 414 419Notes:1.
