Flygt Concertor Eliminates Clogging At Cowansville Pump Station

Despite its small-town charm, Cowansville had an unpleasant wastewater issue. One of the town’s pump stations, which receives wastewater from the neighboring municipalities of Brigham and East-Farnham, as well as septic tank sludge from the Enviro-5 treatment center, was experiencing a constant buildup of solids and fat.

The pump station is the fifth largest substation the Cowansville utility operates, with a capacity to pump 350 cubic meters per day (0.092 MDG). Despite the comparably low levels of wastewater, the pump station was faced with frequent instances of clogging due to high levels of debris, including wet wipes, rags and solid materials.

Constant grease accumulation also posed a problem for the pump station, with buildup reaching up to 45 centimeters (18 inches) in as little as three months. As a result, the station was shutting down at four or five times per year so station operators could unclog and clean the pumps.
