Dual Auger System Eliminates Clogged Pumps at Drake Pump Station

The Drake Pump Station, located in Saginaw, Michigan, experienced chronic pump maintenance due to flushable wipes. Although the dry pit pump station represented only 0.1 million gallons per day of flow in the city’s collection network, it required a substantial amount of servicing — up to three times a week. This consisted of two operators spending four hours manually removing rags in a confined-space entry to clean out the clogged pump. It was a dirty, unplanned and time-consuming task.

In partnership with the City, Duperon Corporation adapted a proven screening system for a novel application. Deployed inside a 19-inch manhole, the system uses three existing Duperon technologies to screen, compact and transport collected debris 26 feet vertically without auger-assisted conveyance. For the duration of the testing period, the City had zero instances of clogged pumps resulting in a potential labor and maintenance savings of over $41,000 annually.
