<br /> . <br /> . Lift St:ltion Number 9 <br /> .- Location: Ridgewood Road <br /> Type: Wet weill Dry well <br /> Manufacturer: Smith & Loveless <br /> . Construction: Concrete wet well, Steel tube dry well <br /> Design Capacity: 200 gpm at 56 feet TOH <br /> Constructed: 1960, no major modifications <br /> . <br /> Comments: <br /> . Operating personnel indicate tbat tlris station bas been relatively trouble free and requires <br /> only rontine maintenance. The exterior portion of the dry well appears to be in relatively good <br /> condition with minor spots of corrosion typical of this type of structure. The interior was not <br /> . viewed but it is anticipated that there are some additional spots of corrosion which should be spot <br /> repaired as necessary, <br /> DUling wet weather conditions occasionally both pumps will operate together indicating <br /> . increased wastewater flows probably due to some infiltration/inflow in the setvice area_ <br /> This lift station bouses a flow meter owned and operated by the Metropolitan Council <br /> Environmental Setvices (MCES). The flow meter measures and records wastewater flow data <br /> . from the south central portion of Arden Hills. <br /> Preliminary Reco=endations: <br /> .. In general the station is in good condition and the routine maintenance program is doing a <br /> good job of maintaining the equipment. With any steel dry wells it is important to routinely <br /> . inspect the access tube and the floor for corrosion and clean and spot coat or repair as necessary. <br /> Lift Station Number 10 <br /> . Location: North Cleveland Avenue <br /> Type: Submersible pumps in wet well <br /> . Man ufa cturer: Hydromatic Pumps <br /> Construction: Concrete wet \vell <br /> Design Capacity: 100 gpm at 33 feet TOH <br /> . Constructed: [990, Startup in 1994 no modifications <br /> Comments: <br /> . This lift station was installed in 1990 to serve anticipated development which was <br /> subsequently delayed so the "start up" was delayed for several years following the original <br /> construction. The station runs very little at this time and there have been no problems with the <br /> . operation thus far <br /> Preliminary Recommendations: <br /> . Since this is a the first lift station in the City with "submersible pumps" the maintenance <br /> personnel have had to develop new maintenance procedures in conjunction with the pump <br /> .. supplier At this time it appears that the process is working well and no modification is required. <br /> . <br />
