'I well appears to be in fair condition but the floor is significantly corroded .- TIle wet well is a concrete strucnue which appears to be in good condition. Accprding to operating personnel, this station has ben operating reasonably well and I required ollly routine maintenance except for the impeller, volute and motor repairs in [993. Preliminary Recommendations: I TIle dlY well floor and the corroded spots in the access tube and cover should be cleaned and recoated to provide corrosion resistance. Regular preventive maintenance procedures that I are currently in use have dOlle a good job in maintaining the facility and we would recommend a continuation oftlle current program. I Lift Station Number 5 Location: County Road E at Sclunidt Park I Type: Wet well! Dry well Manufacturer: Custom Built, PACO Pumps I Construction: Concrete wet well and dry well inside building Design Capacity: 900 gpm at 78 ft TDH (one pump) Constructed: 1977, major upgrade in 1983. I Comments: .1 The [983 upgrade work included the installation of new long shaft pumps with the drive motors installed on a concrete slab at ground level, and construction of a small building over the wet well and dry well, and replacement of the pump controls. I TIle wet well is under the building and access is provided in a separate room with a separate access door from the outside. Electrical controls and the pump motors are located in an adjacent room with separate access to the outside. The wet well side appears to be in relatively I good condition but there are safety concerns due to the confined space classification of this type of design. The dry well side is in good condition and the pumps have been running well with routine maintenance according to operating personnel. In August 1995 one of the pumps needs a I new volute and the repair parts have been ordered. The pump control system was modified by .Aid Electric to operate on a bubbler system after problems were encountered with the original equipment. There is a concern that the controls are somewhat customized and it may be difficult I for another contractor to make funue repairs. Preliminary Recommendations: I In general the station is in good condition and the routine maintenance program is doing as good job of maintaining the faciliry, The wet well has some safety considerations which are I kno\VTI by operating personnel and safery precautions are observed when working in this . environment. The new pump volute 'vill be installed at the station as soon as it is available from the I service contractor. . I I
