Elk River <br />Municipal Utilities <br />13069 Orono Parkway <br />Elk River, MN 55330 <br />February 7, 2007 <br />To: Elk River Municipal Utilities Commission <br />Jerry Takle <br />Jim Tralle <br />Jerry Gumphrey <br />From: Bryan Adams <br />Subject: Proposed Well <br />~ phone: 763.441.2020 <br />Fax: 763.441.8099 <br />Due to the continued increase in water usage in Elk River, the 2007 budget contains a <br />$400,000 line item to construct an additional well. This well should be operational by the <br />summer of 2008. Attached is an annual load profile of our water demands. Because of <br />the large disparity between summer and the other season's usage, a peaking well with <br />minimal treatment is desirable. This well would only be used in the summer during <br />periods of heavy lawn sprinkling. Attached is a map of our potential well site in east Elk <br />River. <br />Our preferred site is at the Johnson Street Water Tower site. A test well was constructed <br />at this site. The test well reflected great water quantity, but the water quality would <br />require treatment. This well is high in iron and more importantly high in radium 226 and <br />228. An approximate $1,500,000 treatment plant would be required. <br />The well site in Twin Lakes Estates has good water quality and quantity but will require a <br />small (10' x 15') building to inject fluoride and chlorine. A building may be <br />objectionable to the neighbors. The other option is the River Park development, but a test <br />well should be completed at a cost of $23,000 f. <br />Staff recommends constructing another test well at the River Park location to verify our <br />options. <br />
