1 <br /> 3 <br /> 1 A. Lift Station Should_. :Be Replaced <br /> 2 He- said his firm was. recommending a new lift:.station be constructed <br /> 3 next to the existing one and • estimated- the cost of doing that would . <br /> 4 be- $198 000. The .re•asons- he gave for replacement were that: - <br /> 5 *the station had been built 'in 1962 -and; with both pumps in opera- <br /> 6 tion, only 1 , 000 gallons per minute were being. pumped with a head <br /> 7 of 59 feet, where the original design had called for a pumping <br /> 8 capacity of 1 , 200 gallons per minute for each pump to serve the <br /> 9 area north of "37th Avenue. N.E. , once it was fully developed;. <br /> 10 *there may -have been a problem with the original head computa- <br /> 11 tions which differed greatly from the figures the engineers had <br /> 12 come up with now; <br /> 13 *the soil around the station was very corrosive, which has dam- <br /> 14 aged the structure and its current location near the potato chip <br /> 15 factory may have overtaxed the facility; <br /> 16 *by delaying replacement for two or so years , the City would be <br /> 17 just_ pouring more money into repairs for which parts .ar.e very <br /> 18 difficult to find, or not being manufactured at all anymore ; <br /> *the pump would likely be overloaded during periods of very wet <br /> 20 weather like the storm the City experienced July 23rd; <br /> 21 <br /> 22 *life of a new station wouldibe between 2.5 and 40 years ;. . <br /> 23 *the well is not unsafe at this time but should be replaced <br /> 24 before it gets into that condition. <br /> 25 B. Force Main Would Not Require Immediate Replacement <br /> 26 The engineer said, although the above equipment was old and had <br /> 27 less friction rate than was desirable, it was still in reasonably <br /> 28 good condition', however, because it would cost a great .deal to dig <br /> 29 down to -actually verify this .condition, Mr. -Christofferson recom- <br /> 30 mended that',- -if the City upgrades any of the adjacent. streets, a <br /> 31 sample of the force main and the surrounding. soil be taken to be <br /> 32 sent to: the Cast Iron Institute, who will do the tests free-.of' <br /> 33 charge. <br /> 34 :C. Public. Works Director Concurs with Engineering Study <br /> 35 : - Mr. -Hamer told Councilmember '.Makowske the.. report "only: echoed" what. <br /> .36 he had.been telling "the. Council for the--last...seven .years'. He <br /> 37 - acknowledged that . t-he . City- had gotten that many more. years- out .of <br /> 8 the old facility, but indicated he was disappointed money -had not. <br /> �j <br /> been -put away over that-' period to make..the necessary replacement.. . <br /> 40 now. <br /> r <br />
