9789.22 <br />14, <br />TO: Mayor and City Council <br />FROM: Mark E. Bernhardson, City Administrator <br />DATE: September 7, 1989 <br />SUBJECT: Well/Highway 12 <br />Attachment: A. Well/Highway 12 Memo Dated 8/10/89 <br />B. Bid Tabulation and Cover Letter <br />ISSUE <br />1. Decision as to whether the bid for the test wells should be <br />drilled on Highway 12. <br />2. If directed to be drilled, award of bid. <br />INTRODUCTION - In order to develop the well for the Highway 12 it <br />is necessary to undertake test drillings to determine an adequate <br />supply for a 500 gpm well. <br />DISCUSSION - The bid allows for r phases with Phase 5 to be bid <br />in October -November. <br />Phase #1 Test well/Site #1 (Otten) to the Prairio du Chien <br />aquifer. If adequate water is found no further tests <br />will be necessary and Phase 44. <br />Phase #2 Test well/Site #2 to Prairie du Chien. If Phase 1 isn't <br />sufficient r; test at Site 2 (Rebers rear lift station) <br />will be done. If adequate go to Phase #4. <br />Phase #3 Site #1/Test well to Mt. Simon/Hinckley aquifer. While <br />there is adequate water, the test will determine level <br />of radium. <br />Phase #4 Interim "Productior" well. If needed this will be <br />developed to provide water to the area until the Phase <br />#5 well is installed. This well (50 gpm) would be <br />eventually taken over by Cliff Otten. He would <br />contribute to its drilling. As alternatives a.) Cliff <br />Otten could individually drill a well which the City <br />could use and share costs on an interim basis or b.) The <br />City could tap an existing residential well presently <br />owned by Mr. Otten. <br />Phase #5 Municipal Well (500 gpm). This would include drilling a <br />12" well to the appropriate aquifer determined by the <br />test drillings. While this could be bid and possibly <br />drilled before winter, construction of the pump house <br />
