South Deerfield Wastewater Treatment Plant
Located in the heart of the picturesque Pioneer Valley in Western Massachusetts, the Town of Deerfield and the South Deerfield Wastewater Treatment Plant both sit nestled at the foot of beautiful Mt. Sugarloaf. The state reservation atop the mountain boasts of one of the finest views in New England with the Connecticut River snaking its way south past the Holyoke Range, the majestic buildings of UMASS Amherst sprouting up from farmland, quaint South Deerfield center, and the South Deerfield Wastewater Treatment Plant all within ready view.
The South Deerfield facility, along with scores of other treatment plants up and down the Connecticut River, has been instrumental in the cleaning up of New England's longest waterway over the last 40 years. What was once the butt of jokes concerning unmentionable floating objects in the river, is now a fishable, swimmable Class B river. We have much to be proud of as a people for allocating the requisite funds and training the wastewater professionals necessary to get the job done.

Treatment Processes
Comminutor with backup bar rack, (2) complete mix aeration tanks, 60' Dorr-Oliver circular center-feed final clarifier, chlorine contact chamber, 9" Parshall flume, Regal vacuum chlorinator, 150 pound chlorine gas cylinders for chlorination, 26,000 gallon sludge holding tank, Penn Valley dual diaphragm sludge pumps, one-meter PCL belt press (idle).
Sludge Handling
Sludge is concentrated to 1.5% in the bottom of the circular clarifier by shutting of the return pumps for 2 to 4 hours. We then pump the settled sludge to a holding tank while adding a coagulant en route using two small chemical feed pumps. The flocculated sludge settles and topwater is pumped out with a small centrifugal pump back to the headworks the next morning before our liquid sludge hauler arrives. We average 50% topwater removal which leaves us with a final sludge averaging 3.0% solids. Presently, our material is taken to the Montague WWTP for handling.
