<br />CDM <br /> <br />Section 3 <br />Water Use and Forecasted Demands <br /> <br />3.1.3 Historical Water Use and Customer Type <br /> <br />Figure 3-4 shows the average water use by sector from 2001 to 2005. These data show <br />that residential households comprised 64 percent of Erie's total water consumption. <br />Unbilled water is the second highest consumptive use, at 15 percent. This includes <br />pipe leakage, unmetered water use, and meter error. Unmetered water is used for fire <br />fighting, street cleaning, sewer cleaning, and water line flushing. Construction uses <br />and commercial uses were the next highest water consumers, while parks and <br />institutional sectors represented the categories of least use. <br /> <br />2% <br />30/0 <br />90/0 <br /> <br />15% <br /> <br />64010 <br /> <br /> <br />o Residential <br />o Parks <br /> <br />.

This indicates that <br />although the community has been growing and collectively using more water, the <br />amount of water used per capita has remained below 2002 levels. As previously <br />mentioned, this is likely attributable to the regional drought awareness campaigns, <br />Erie's efforts to conserve water, as well as higher levels of precipitation in 2004. Given <br />these multitude of factors, it is difficult to precisely quantify the amount of water <br />savings directly attributable to Erie's conservation efforts. Table 2-7 provides <br />estimated savings for conservation measures where estimation could be made with <br />reasonable accuracy. <br /> <br />DRAFT <br /> <br />3-4 <br /> <br />\\DENSVR1\PROJECTS\9228 - ERIE\CONSERVATION PLAN\REPORT\DRAFT PRIOR TO PUBLIC REVIEW\CONNIE FORMATTED\SECTION 3.DOC <br />
