Massachusetts Water Resources Authority

Charged with cleaning up the Boston Harbor, the Massachusetts Water Resources Authority (MWRA) awarded a contract to permit, design and construct a facility to transport liquid sludge via barge, process it into a Class A biosolids product, and beneficially use the product. The MWRA currently delivers its sludge to the facility via underwater pipelines and the barges are no longer used.

Successful equipment lifecycle maintenance and upgrades is well demonstrated in the Quincy facility with some of the original equipment still in service. All dryer trains have been maintained and components repaired and upgraded within the same footprint as the original installation more than 30 years ago.

Product produced at the Quincy facility is used both as a fertilizer and as an alternative fuel.
