The $143 million sludge drying facility was constructed in 2015 and is operated by NEFCO.(New England Fertilizer Company)
It dries wastewater sludge from the Wastewater plant for wholesale sale as fertilizer and bulk material usage. The facility can produce up to 420 dry tons per day of fertilizer pellets, a nutrient source used by farms on their fields or as an alternative, renewable fuel source for facilities such as power plants or cement kilns.

A 20-year contract with privately held NEFCO for $683 million in 2013, encouraged the sewage authority to adopt the biosolids-to-fertilizer concept as a means to resolve chronic violations for excess sludge at the wastewater treatment plant. The dryer facility also enabled the plant to cease operation of six, 50- to 70-year-old sludge incinerators that required major, expensive upgrades to comply with toughened air emissions standards which took effect in March 2016.
