P.W. CASE #6 CONSIDER HIRING CONSULTANT TO BEGIN DESIGN OF NEW MUNICIPAL WELL By: Brian E. Olson, Assistant Director of Public Works/Principal City Engineer Background: The Alternative Urban Areawide Review (AUAR) for the Ramsey Town Center that was completed last summer indicated that the Ramsey Town Center will create a future water demand of 595 million gallons of water per year (MG¥) (see attachment, page 13-6 of AUAR). This will require an amendment to our appropriations permit that we receive from the Department of Natural Resources (DNR). Last year we pumped approximately 506 MGY with our five (5) existing production wells. The improvements to our water supply system that are needed begin with the addition of 3 additional production wells over the next few years as indicated in the 5-year Capital Improvements Pro,am. During the process of the AUAR, we received concerns from citizens and regulatory agencies such as the DNR regarding the availability of water within the Franconia Iron Galesville (FIG) aquifer as well as the connection between the surficial aquifer and the FIG. To ensure that there was water available and little connection between the surficial aquifer, the AUAR suggested implementation of a monitoring plan. On July 25, 2003, we met with key Staff people of the DNR to work on the details of the monitoring plan. Enclosed are letters from Bolten and Menk as well as the DNR summarizing the discussions. With the assistance of Bolten and Menk as well as Roger Renner (EH Rennet Well Drilling) we were able to put together a monitoring plan that we believe meets the intent of those discussions. The cost of the implementation ($85,930) of the monitoring plan and design work needed to complete the first of the 3 new production wells (Well No. 6) is included in the attached proposal from Bolten and Menk. The cost of this work has been estimated at $350,000 and includes the well drilling, and associated piping necessary for connection of Well No. 6 to the existing pump house (Pump House No. 3) where the addition of chlorine, fluoride and polyphosphate will occur. The intention is to have this well operational by mid August of 2004. A detailed cost estimate and schedule will be prepared for Well No. 6 before the project gets author/zed for bidding. Recommendation: Staff recommends hiring Bolten and Menk for an amount not to exceed $85,930 to perfo~Tn the design work necessary for Well No. 6 and to implement the monitoring plan after approval from the DNR.
