Agenda Section: VI-2 <br /> CITY OF NEW BRIGHTON gri <br /> Report Number: - -053 <br /> REQUEST FOR COUNCIL CONSIDERATION <br /> Report Date: March 11, 1997 <br /> 411 <br /> ITEM DESCRIPTION QUOTES FOR MAINTENANCE AND REPAIRS <br /> ON CITY WELL 5& 8 PUMPS <br /> DEPT. HEAD'S APPROVAL: r• <br /> L <br /> MANAGER'S REVIEW/RECOMMENDATION: <br /> /, <br /> No comments to supplement this report jP� p Comments attached <br /> EXPLANATION/SUMMARY (attach supplemental sheets as necessary) <br /> The purpose of this item is to obtain Council authorization to proceed with routine maintenance and repair work on well pumps in City <br /> Wells 5 and 8.The majority of the work will be routine maintenance consisting of pulling the well pumps, inspecting them,replacing <br /> worn and corroded parts and reinstalling them. Well 5,which is located at 3001 -5th Street NW,has last been pulled for maintenance <br /> in November of 1991. It has produced 670 million gallons of water since November of 1991.Well 5 is part of the ground water <br /> remediation system and the maintenance and repair cost will be paid from the Army 20 year operation and maintenance fund. <br /> Well 8, located at 600 Silver Lake Road,is one of the City deep aquifer wells and was last pulled for maintenance in 1991. It is used <br /> primarily to meet peak water demand periods and therefore does not get a lot of usage. It has only produced about 145 million gallons <br /> of water and needs to be pulled for maintenance because of the long period of time it has been in service. Whereas we expect to see <br /> wear on the well 5 pump due to the high usage, corrosion may be more of a problem with the pump in well 8.The repair cost for well 8 <br /> •Ould be paid from the City water fund.The following quotations have been received for the maintenance work: <br /> Well 5 Pump Maintenance Well 8 Pump Maintenance <br /> Alberg Water Service $ 8,728.00 $10,858.00 <br /> Bergerson Caswell $10,016.00 $14,431.00 <br /> Keys Well Drilling $10,872.00 $13,177.00 <br /> E.H.Renner and Sons $13,616.00 $17,808.00 <br /> The quotations are based on estimated work and parts that may be required.The actual cost per well typically runs in the neighborhood <br /> of about$25,000, if major parts need to be replaced or if the wells need to be cleaned of sand. We recommend that Council authorize <br /> the expenditure of up to$25,000 per well, and if the final cost exceeds$25,000 we will report back at a later date for further <br /> authorization.All of the above contractors have preformed satisfactorily on past City work and we recommend that this work be <br /> awarded to Alberg Water Service who has submitted the low quote for both well pumps <br /> RECOMMENDATION <br /> To APPROVE THE QUOTATIONS FROM ALBERG WATER SERVICES FOR THE MAINTENANCE WORK ON THE WELL <br /> PUMPS 5 AND 8 AND AUTHORIZE THE EXPENDITURE OF UP TO$25,000 PER WELL FOR THE MAINTENANCE <br /> WORK. <br /> 111/ <br /> Brian E.
