Lift Station No. 6 Improvements
City of Lakeville, Minnesota
The City of Lakeville's existing Lift Station No. 6 was originally constructed 30 years ago as a Smith & Loveless "tin can" wet well/dry well station. Although the station remained in service, its age was causing it to deteriorate. City employees had difficulty accessing the service pumps because of the buried dry well. The station was also a major source of scum and grease buildup, which required the city to remove the grease every two months.
Bolton & Menk designed a new lift station, which included a wet well structure with submersible pumps and a valve vault structure to house check and isolation valves. A submersible mixer on a separate rail system keeps grease and solids in suspension so they are pumped out of the station with the rest of the wastewater. A new control panel, SCADA equipment, and Caterpillar generator were also included in the project.
The wet well with submersible pumps allows the city to remove and service pumps and other equipment from the surface. The submersible mixer greatly reduces the frequency in which city employees need to clean the station. The new expanded drive gives city employees room to park multiple vehicles at the station without obstructing the street. The city now has a new, fully functioning lift station that will last for many years.
