City of Nashua, Public Works Division
Board of Public Works Meeting Date: September 20, 2018
David L. Boucher, Superintendent
Wastewater Department
Casella Organics
To approve change order 1 to the three year contract with Casella Organics of
Concord, NH for the management of Wastewater Biosolids in the amount of
$260,000. Funding will be through: Department: 169 Wastewater; Fund:
Wastewater; Account Classification: 54 Property Services.
Casella Organics was approved for a three year contract for the management of
the Wastewater Facility’s biosolids at the February 29, 2016 BPW meeting.
This change order will be for $260,000, which is estimated based off of the
remaining eleven invoices expected to complete the three year term. It is
determined that the need for these additional funds is due to the lengthy digester
cleanout project and the need to dispose of non-class B biosolids at a cost of $89
per wet ton, instead of $40.90 per wet ton.
