Ms. Maryanne C. Bach <br />12/28/2001 <br />Page 4 <br />since 1966 is 30 %. This volume is also 226% of the average volume reclaimed since 1966. <br />These figures reflect the above - discussed correction for water year 2000 successive use. <br />Denver continues to actively pursue maximizing its use of Colorado River return flows. <br />During 2001, Denver continued to pursue implementation of the Denver Board of Water <br />Commissioner's near term water supply strategy for producing 55,000 acre -feet of water <br />needed to extend Denver's water supply to the year 2030. The strategy contains the <br />elements of non - potable reuse, small -scale system refinements, water conservation, and <br />cooperative supply projects. These elements were selected after completion of Denver <br />Water's Integrated Resource Plan (IRP). The IRP is in the process of being revised and <br />updated. A new report is expected in 2002. <br />Water Recycling Project. In 2001, Denver Water began construction of its Water Recycling <br />Project (formerly known as the Nonpotable Reuse Project). The Recycling Plant will <br />receive effluent from the Metro Wastewater Reclamation District wastewater treatment <br />plant and further treat the effluent so it can be delivered for irrigation and industrial uses. <br />Plans call for construction in three phases, with the third phase bringing the total amount <br />of water served to over 17,000 acre -feet per year at a maximum rate of 45 million gallons <br />per day. The first phase of operations is scheduled to begin in 2004. <br />Nonpotable reuse will enhance Denver's successive use of Colorado River water. Denver <br />has made agreements for annual delivery of over 9,000 acre -feet of recycled water with <br />future users. Public Service Company of Colorado has committed to 5,200 acre -feet of this <br />total for use at their Cherokee Power Plant. Also, the Rocky Mountain Arsenal plans to <br />use about 1,200 acre -feet of recycled water and Denver International Airport will use <br />about 900 acre -feet per year. The remaining commitments are from irrigation and various <br />other municipal users. <br />In conjunction with the Water Recycling Project Denver Water began preparing <br />applications to the Water Court in Water Division 1 for operations of the Recycling Plant <br />and Denver's future downstream reservoirs. Denver expects to file these applications by <br />the end of calendar year 2001. <br />5ystem Refinements. <br />Lawn Irrigation Return Flow. In 2001, Denver completed its second year of analysis of <br />the amount of reusable return flows from irrigation of lawns within its service area. The <br />engineering work has thus far been focused on developing additional hydro - geologic data <br />and measurement of irrigated areas. Over $435,000 has been expended of the $2 million <br />budgeted for the completed analysis, due at the end of 2004. Denver Water expects that a <br />number of years beyond 2004 will be needed to negotiate a water court decree with other <br />water users permitting the legal use of these return flows. Once quantified and decreed, <br />the return flows will be an additional amount of reusable water available for successive <br />use such as exchange or delivery to its raw water facilities or for delivery to other <br />nonpotable uses in the metro area. <br />
