1 CASE # f �, I PROPOSAL TO RETROFIT WELL NO. 1 TO INCREASE PUMPING CAPACITY By: Steve Jankowski, City Engineer ' Background: You will recall that the City recently retained BRA Inc. to develop Well No. 3 to increase the water ' utility's water sources. Unfortunately, the well will not be available for the peak day uses which occur during the hot summer months and, as a result, we will have to rely on the purchase of water from the City of Anoka to meet our peak days this summer. I project that on the peak summer day we will need to purchase 1.4 million gallons of water. This exceeds the target supply level of one ' million gallons per day discussed in our original agreement with Anoka. The current water agreement proposed by the City of Anoka provides for substantial increases in ' fixed monthly charges as the peak use day exceeds the one million gallon threshold. It would be extremely helpful to reduce our dependence on the City of Anoka. In reviewing the original well development records for Well No. 1, and by performing some ' additional test pumping late last month, it became apparent that Well No. 1 could be capable of producing as much as 900 gpm in contrast to its current production of 550 gpm. This would require the replacement of the current pump with a higher capacity pump and meter. ' At the time of this writing, I am awaiting information detailing the cost of the retrofit, however, I do expect the artiount to run in the neighborhood of $40,000. There will be some rebates available for the upgrades associated with more energy efficient equipment. In addition, I anticipate some long -term savings on operational cost due to the higher efficiency of a line shaft turbine pump versus the existing submersible. ' Time is also a critical factor in this upgrading. It is anticipated that the pump and motor will have a two -week delivcry time, plus I would anticipate it may take from one to two weeks for the installation. It 'would be possible to have the installation complete by the first part of May if approval was gLVen at tonight's meeting and the City purchased equipment and installation labor separately throu' h the quotation process. Since the cause of this expense is directly related to the growth in the utity customer base, these costs should be considered appropriate for funding from the WAC Fund or Utility Reserve Funding. ' Council Action: ' Based upon supplemental information and discussion. Reviewed by: ' City Engineer City Administrator Finance Officer CC: 03/26/96 rmt I wi
