The town of Sutton, Massachusetts is a small community of approximately 9000 residents. Originally settled in 1662, Whitinsville is a small rural community outside of Sutton with a population of 6,704 people located about 50 miles west of Boston. With support from Kats Pump Service, the contractor for the Sutton municipality, CP&S was able to install a Sithe Chopper pump at the Whitinsville pump station in July of 2017. The Whitinsville pump station is the second of three pump stations in a series that collect wastewater from the local community and pump it on to the Sutton treatment plant. The stations serve the local community which includes roughly 100 homes and small businesses.

While stations within the municipality are cleaned with a vacuum truck quarterly, the station in Whitinsville exhibited a considerable amount of floating grease debris despite being cleaned roughly two weeks prior to CP&S’s visit. The pump installed in the station was jamming on average once a month and needed to be cleaned or deragged in order to return to operation. The pump was typically jamming due to nonwoven flushable wipes.

CP&S field team successfully replaced the competitors’ pumps with a 20 HP Sithe Chopper pump. The installation was quick and painless, requiring no modifications to the rails or panel. Since the installation of the Sithe a year ago, the town of Sutton has had less service calls to clean the station resulting in a 75% reduction in service costs. The Sithe is able to pump the same amount of sewage in half the time allowing for a 25% reduction in run time. Additionally, the grease debris build up has been alleviated, providing a cleaner and more efficient station.

PAIN POINTS:

• Station cleaned with a vacuum truck quarterly
  •  Station exhibited a considerable amount of floating grease debris despite being cleaned two weeks prior to visit
  •  Existing pump jams on average once a month and needed to be cleaned and deragged in order to return to operation
  •  Pump typically jammed on flushable wipes

SOLUTION:

• 20 HP Sithe Chopper installed to replace existing non-clog pump
  •  Run time of pump reduced by 25%
  •  Service costs of vacuum truck and cleaning reduced by 75%
  •  Grease debris build up alleviated improving station efficiency
