r <br />.. <br />• <br />CITY OF LA PORTE <br /> <br />INTER-OFFICE MEb40RANDUM <br />T0: Jerry Hodge, Director of Public Works DATE: Dece'~,m'~bjJer 5, 1983 <br />FROM: Luther Maxey, Assistant Director of Public Work ~/I// <br />SUBJECT: Fairmont Water Booster Station t <br />The large booster pump at Water Station ~fl is an Aurora 750 gpm pump <br />which has a worn down impeller, wear plates and a bad outboard bearing <br />which has scored the pump shaft. We have contacted Aurora <br />Pumps, Inc., for availability of repair parts. The pump is outdated, <br />and Aurora is having difficulty locating the necessary parts. <br />I strongly recommend that the City purchase a complete replacement <br />pump. Jackson Ray, Purchasing Agent, has located a replacement <br />pump for $4,700 (FOUR THOUSAND SEVEN HUNDRED DOLLARS). Estimated <br />repair cost of the old pump is $2,600 .(TWO THOUSAND SIX HUNDRID <br />DOLLARS) to $3,500 (THREE THOUSAND FIVE HUNDRED) depending on <br />availability of parts. It appears we could be waiting for eight (8) , <br />to twelve (12) weeks for parts while the new pump could be installed <br />• by December 9, 1983. <br />This matter should be handled on an emergency basis due to the fact <br />that the second pump is ~nlv rated at 500 $pm, and we have noticed a <br />thirty percent (30~) reduction in efficiency over the past nine (9) <br />months. If Fairmont is isolated from the rest of La Porte (such as <br />leak shutdown on the 16" main along West Main); the remaining pump <br />will not provide service to all of the Fairmont area. <br />Funds for this pump should come from Water and Wastewater Contingency <br />account #003-810-810-000. <br />LM/me <br />• <br />
