Adams <br /> <br />Sklbject: <br /> <br />Future Water Production Facilities <br /> <br />The Elk River Municipal Utilities (ERMU) Commission has had a number of discussions <br />recently concerning our communities gro,,v-th and the need fbr more water production <br />facilities. The ERMU currently operates 5 water production facilities and an additional <br />facility will be completed in June, 2002. This represents a daily pumping capacity of 6.4 <br />million gallons per day with the new facility. 2001 maximum daily pumping <br />requirement was 5.3 million gallons. This is a lot o£ water for a community our size. <br />Elk River's water use patterns have changed in the last few years, mainly due to lawn <br />sprinkling. One water production facility could serve 1000 water meters in 1996 but <br />only 632 meters in 2001. The time betv,'een constructing new facilities has decreased <br />from 5 years to 3.5 years, while the cost of these facilities has increased from <br />approximately $1,000,000 to approximately $1,400,000 each. <br /> <br />Elk River currently has approximately 1500 lots in development or in the active plarming <br />stages. This equates to 2.3 water production facilities. To ensure we have locations to <br />construct future water production facilities, the EP~MU Commission has authorized the <br />purchase of the necessary land. The attached sketch reflects possible locations for future <br />water production facilities for eastern Elk River. When locating municipal well, the <br />Minnesota Department of bIealth has criteria to be followed. The first is the isolation <br />distance which is reflected on the attached sheet titled "isolation Distances from a Water <br />Supply Welt". This criteria is to protect the welt head from possible contamination. The <br />other criteria is avoiding contamination in the aquifer. This is achieved by identifying <br />the wellhead protection area dictated by the distance water in the aquifer ,,,,'ii1 travel in 10 <br />years to the ,,veil. See the attached drawing titled "Time of Travel". We are required to <br />consider existing or potential aquifer contamination issues in the wellhead protection <br />area when siting a municipal well. Betbre the property is purchased, generally we install <br />a test well to help identil-y geology, water quantity and water quality characteristics. <br /> <br />When we purchase this property, ,,ye must make it absolutely clear that we not <br />guaranteeing if and when municipal water service will be available to the surrounding <br /> <br /> <br />
