WYFFELS, P.E. DIRECTOR OF PUBLIC WORKS 6A1 <br />CITY MANAGER'S APPROVAL: <br />No comments to sup lement this re ort <br /> <br /> <br />Recommendation: To approve the quotation from Keys Well Drilling for the maintenance work on well pump 4 and <br />installation of draw down transducers. To authorize the expenditure of up to $30,000 for the maintenance work and drawdown <br />transducers installation on well pump 4. <br /> <br />Legislative History: August 23, 2006 Maintenance work on New Brighton well 4 has been approved in the United States <br />Army annual budget for off site groundwater remediation activities in New Brighton at our annual meeting. <br /> <br />Financial Impact: The following quotations were received for the well maintenance work: <br /> <br />Keys Well Drilling <br />Bergerson Caswell <br />E. H. Renner & Sons <br /> <br />Well 4 <br />$16,757.00 <br />$18,820.00 <br />$20,821.00 <br /> <br />The quotations are based on estimated work and unit prices for parts that may be required. The actual cost per well typically <br />runs in the neighborhood of about $30,000. If unexpected major parts need to be replaced or if the well needs to be cleaned <br />of sand the cost would be higher than $30,000. Staff recommends that Council authorizes the expenditure of up to $30,000, <br />and if any of the final cost exceeds $30,000 we will report back at a latter date for further authorization. All of the above <br />contractors have preformed satisfactorily on past City work and staff recommends that maintenance work for Well 4 be <br />awarded to Keys Well Drilling. <br /> <br />Explanation: The purpose of this item is to obtain Council authorization to proceed with routine maintenance and repair <br />work on the well pump in City Well 4. The majority of the work will be routine maintenance consisting of pulling the well <br />pump, inspecting it, replacing worn and corroded parts and reinstalling the pumps. A well drawdown transducer will also be <br />installed in the well. <br /> <br />Well 4, located at 700 Silver Lake Road, and produced 600 million gallons since it was last serviced in April of 2004. It is <br />part of the off site Twin Cities Army Ammunition Plant (TCAAP) groundwater remediation system and is one of the primary <br />pumps for Water Treatment Plant I. <br /> <br />Well draw down transducer will be installed in the well to measure the aquifer water level automatically on the computer. <br />This groundwater elevation information is reported to the Minnesota Department of Natural resources (DNR) each year as <br />part of our DNR Water Appropriations permit. The permit allows the City of New Brighton purchase waters of the state (the <br />groundwater) to pump and sell to its residents and businesses. The current drawdown measurement is done with an air line <br />that have been replaced every well maintenance. The drawdown transducers will last longer, be more accurate and not need <br />an operator in the well house while the pump is running. <br /> <br />Costs and Funding: The cost for the maintenance work and installation of drawdown transducers on well pump 4 would be <br />paid from the Army 20 year operation and maintenance fund. <br /> <br />~~j~ <br /> <br />Kerry T orne <br />Civil Engineer I <br /> <br />G:\liNG\W A TRSPL y\ WELLS\PUMPS\2007\Couneil Report.due <br />
