<br /> . <br /> I well appears to be in fair condition but the floor is significantly corroded <br /> .- The wet well is a concrete structure wbich appears to be in good condition. <br /> Accprding to operating personnel, this station has ben operating reasonably well and <br /> required only routine maintenance except for the impeller, volute and motor repairs in 1993. <br /> . Preliminary Reconnendations: <br /> . 1l1e dlY well floor and the corroded spots in the access tube and cover should be cleaned <br /> and recoated to provide corrosion resistance. Regular preventive maintenance procedures that <br /> are currently in use have done a good job in maintaining the facility and we would reconnend a <br /> . continuation of the cutrent program <br /> Lift Station Number 5 <br /> . Location: County Road E at Schmidt Park <br /> Type: Wet well! Dry well <br /> . Manufacturer: Custom Built, PACO Pumps <br /> Construction: Concrete wet well and dry well inside building <br /> Design Capacity: 900 gpm at 78 ft TDH (one pump) <br /> . Constructed: 1977, major upgrade in 1983. <br /> Connents: <br /> .e The 1983 up grade work included the installation of new long shaft pumps with the drive <br /> motors installed on a concrete slab at ground level, and construction of a small building over the <br /> I wet well and dry well, and replacement of the pump controls. <br /> The wet well is under the building and access is provided in a separate room with a <br /> separate access door from the outside. Electrical controls and the pump motors are located in an <br /> I adjacent room with separate access to the outside. The wet well side appears to be in relatively <br /> good condition but there are safety concerns due to the confined space classification oftms type <br /> of design. The dry well side is in good condition and the pumps have been running well with <br /> . routine maintenance according to operating personneL In August 1995 one of the pumps needs a <br /> new volute and the repair parts have been ordered. The pump control system was modified by <br /> Aid Electric to operate on a bubbler system after problems were encountered with the original <br /> . equipment. There is a concern that the controls are somewhat customized and it may be difficult <br /> for another contractor to make future repairs. <br /> I PreliminalY Reconnendations: <br /> In general the station is in good condition and the routine maintenance program is doing <br /> . as good job of maintaining the facility. The wet well has some safety considerations wbich are <br /> known by operating personnel and safety precautions are observed when working in this <br /> envTIonment. <br /> . The new pump volute \\iill be installed at the station as soon as it is available from the <br /> service contractor. <br /> .e <br /> I <br />
