Charlemont Wastewater Treatment Plant - Charlemont, Massachussetts
The Charlemont Wastewater Treatment Plant, which is situated at the confluence of the Deerfield River and Mill Brook, was severely damaged during tropical storm Irene. Fast flowing flood waters completely inundated the treatment plant site causing significant damage to the plant’s recirculating sand filters, underground treatment tanks and overall site. Flood waters scoured the sand filter interiors causing significant deposits of river silt and debris. The Charlemont Sewer District retained Nathan L. Jacobson & Associates to design repairs to the wastewater treatment facilities, which included contingency operations, removal of large fiberglass chamber covers, removal and disposal of all silt laden filter media, underdrain stone and distribution piping, and removal of river silt from treatment tanks and pump chambers. Filter chambers were cleaned and provided with new underdrain stone, filter media and piping and wastewater pumps were repaired and reinstalled. Brian Curtis, P.E., served as design engineer on the project. Treatment facilities were brought back on line in 2012 and are once again producing a high quality effluent.
