Lift Station 14

City of Maplewood, Minnesota

The City of Maplewood needed to convert an existing wet/dry well cast-in-place concrete station, as the existing pumps and controls required replacement. Bolton & Menk's design incorporated converting the dry well to a valve vault, and the existing wet well to a submersible lift station. The existing lift station was a cast-in-place concrete structure. Retrofitting the existing top slab with new hatches was not practical, so a top slab was designed with new hatches. In addition, a control panel with a cellular alarm/SCADA dialer was installed. Sanitary sewer service was never interrupted during construction as bypass pumping occurred throughout construction.
