1/..-:/ I Lift Stntion Number I I- Location: Arden Hills Trail Type: Wet well! Dry well Manufacturer: Smith & Loveless I Construction: Concrete wet well, Steel tube dry well Design Capacity: 200 gpm at 31 feet TDH . Constructed: 1959, modifications - cover was replaced and access tube extended with grading changes for parking area; 1993 New electrical service was installed; no major pump' or motor modifications. . Co=ents: The dry well tube and cover were modified when the adjacent to\Nll house units were I constructed and the replacement cover is somewhat distorted and corroded, In 1993 the electrical service was replaced by i\id Electric, and the overall station was checked out but there was no work done on the controls. . According to operating personnel the station is relatively trouble free except for routine maintenance. During wet weather conditions, there is an increase in the pump running times indicating some infiltration/inflow in the service area of this lift station. . Preliminary Reco=endations: .e The wet well cover needs replacement or at least some repair and recoating for corrosion protection. The dry well tube and floor should also be inspected and possibly spot cleaned and recoated as necessary. I Lift Stntion Number 2 I Location: Easement west of Chatham Avenue Type: Wet weW Dry well . Manufacturer: Custom Built, PACO Pumps Construction: Concrete wet well and dry well inside building Design Capacity: 900 gpm at is ft TDH (one pump); 1100 gpm at 89 ft IDH (two pumps) I Constructed: 1977, major upgrade in 1983 Co=ents: . The 1983 upgrade work included the installation oflong shafts on the pumps with relocation of the drive motors to a ground level concrete slab, and construction of a small building . over the wet well and dry' well and replacement of the pump controls. This station was not viewed, however according to operating personnel, the construction is similar to the building at stations 5 and 8. In these locations, the wet well is under the building ~ ~ . and access is prov~ded 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 separated access to the outside. There are safety concerns on the wet well side due to the confu1ed space classification of .e this type of design, The dry well side prov~des good access to the pumps and mOlOrsfor .
