<br />CDM <br /> <br />Section 3 <br />Water Use and Forecasted Demands <br /> <br />This section describes Erie's annual water demands, water use by customer type, and <br />potable and non-potable uses. Forecasted annual water demands through 2025 are <br />also provided. <br /> <br />3.1 Current Water Use <br /> <br />Water use within a community is affected by a variety of factors including population, <br />land use, climate conditions, drought awareness, and conservation efforts. This <br />section describes Erie's water use from 1998 to 2006 and identifies how those demands <br />may have been influenced by the aforementioned factors. <br /> <br />3.1.1 Historical Annual Water Use <br /> <br />Figure 3-1 shows Erie's total annual water use from 2001 to 2006. Total water use <br />consists of potable, raw water and leases of non-potable water from other providers <br />(raw water/leases), and reclaimed water (Section 2.6 provides information on <br />reclaimed water). The raw water and leases consists of water used to irrigate Vista <br />Ridge from 2002 to 2006 and Erie Commons in 2006. Reclaimed water was also used <br />to irrigate Vista Ridge from 2002 to 2006. <br /> <br /> 4,000 <br /> 3,500 <br />G:: 3,000 <br />~ <br />Q) 2,500 <br />en <br />:J <br />!.... 2,000 <br />Q) <br />~ 1,500 <br />ro <br />::::J <br />c 1,000 <br />c <br /><( <br /> 500 <br /> <br /> <br />o <br /> <br />2001 <br /> <br />2002 <br /> <br />2003 <br /> <br />2004 <br /> <br />2005 <br /> <br />2006 <br /> <br />o Potable Use <br /> <br />.

Raw water diverted from Coal Creek to irrigate Vista Ridge was not available for 2003. It <br />was assumed 2003 diversions were the average of 2002 and 2004 diversions. <br />2. Raw water diverted from Marshall Lake-Community Ditch (FRICO) for irrigation of Vista <br />Ridge was not available for 2002 to 2004. It was assumed that annual diversions were 100 <br />AFY for this period. <br />3. Raw water diversions for Vista Ridge also include irrigation and construction water. <br />Construction or irrigation water was not independently metered. <br /> <br />DRAFT <br /> <br />3-1 <br /> <br />\\DENSVR1\PROJECTS\9228 - ERIE\CONSERVATION PLAN\REPORT\DRAFT PRIOR TO PUBLIC REVIEW\CONNIE FORMATTED\SECTION 3.DOC <br />
