Department Approval <br />FA <br />WPWA <br />Rls�kspvlffi� <br />REQUEST FOR COUNCIL ACTION <br />Date: 0110108 <br />Item No.: 12.g <br />City Manager Approval <br />Item description: Consider Additional wells for the Campus wide Geothermal Project <br />BACKGROUND <br />On June 9, 20W the City Council authorized an agreement with Harty Mechanical to install a "full" <br />geothermal system at the Roseville Skating Center Arena. At that meeting and previous meetings, there <br />have been discussions regarding the preparation for the future campus wide application. Specifically, <br />this means moving the well field from the initially proposed location of the North parking lot to the <br />South parking lot, drilling 24 additional wells, providing larger piping and increasing the pump size for <br />the ground heat exchanger (GHX). You requested that a price be brought back to you for consideration. <br />The price received is $09,097.91. <br />The proposed price is higher than anticipated and does not appear to provide a significant financial <br />advantage of doing this now. Part of the higher price includes a premium for the additional well drilling <br />due to the drillers schedule issues. Although difficult to predict the future, geothermal is a new venture for <br />the City and without having significant experience, it may be prudent to hold off, learn more, and <br />provide the necessary connections to the campus wide system at a later date. Another consideration <br />would be that the South parking lot pavement does have a longer remaining useful life than the North <br />parking lot. <br />If this component is not selected, the well field would remain in the North parking lot and the future tie <br />in to the other campus wide facilities would occur in alternative fashions. <br />POLICY OBJECTIVE <br />The policy objective with this particular project involves consideration of the cost /benefit to implement <br />sustainable uses for facilities in the city of Roseville as well as long term planning. <br />FINANCIAL IMPACTS <br />The total cost for the moving the well field to the South parking lot of the Skating Center and adding 24 <br />wells to the field to be prepared for the future campus expansion is $69,097.91. <br />STAFF RECOMMENDATION <br />The decision to add the extra wells is a campus wide policy decision and would have very little impact <br />on the Skating Center project specific, except for providing added redundancy. <br />Page 1 of 2 <br />
