Gappa <br />Title Director of Public Services <br />Administrator Reviewed:Agenda Section: <br />Engineer's Report <br />item Description: Repair and Upgrade of Navarre Well Number 2 <br />removal of the well pump, cleaning of the well, and replacement of necessary par <br />the existing capacity of 275 gallons per minute. <br />Th, Navarre water system has two wells. The main well has a capacity of 1,000 0PM and the <br />SIS n^ter 2 has a capacity of 275 GPM. For the past 10 years, the avenge maxtmum <br />day witer H.mand has been 730,125 gallons per day or 507 gallons per mmute. Well <br />has approximately half of the capacity necessary to meet the average maxtnium ay ^ <br />When well number 2 was installed in 1972, it was never test pumped to ‘1'''^'°^ <br />capacity Since this well is short on the backup capacity to meet the n^tmum day <br />it makes sense to develop the well in an attempt to increase the capactty. Standard practice for t <br />ImSngtSr S conLtor to install a temporary pump to complete *is work. Test pumpmg <br />It hfghfr capacities can result in pumping of large quantities of sand and possible damap to *e <br />test pump Ve contractor installed a test pump and developed the well by test pumpmg. <br />'r“ro7uus .1st pumping indicate that a capacity of 500 GPM is <br />recommendation is to upgrade the well pump, to increase the capacity to 500 GPM m order t <br />HonHie the maximtun day demand. This will provide for firm redundant well capactty f <br />maximum day demand. <br />Unon removal of the pump it was discovered that the pitless unit was bent. This unit has ^n <br />taplace since the installation of the well in 1972, is corroded, and may have to be <br />near fiimre. Replacement of this unit in the future would require removal of P“ P- <br />Replacement of diis unit, at this time, before installation of the new pump would be advisable. <br />The cost for replacement of this unit is $5,000.
