Long-Term Management of Wastewater Biosolids

The City of Nashua, New Hampshire, Division of Public Works, is issuing an Invitation for Bids (IFB) for the long-term management of wastewater biosolids generated at the Nashua Wastewater Treatment Facility located at 2 Sawmill Road. The procurement seeks qualified vendors to provide removal, transportation, and disposal services for dewatered biosolids in an environmentally sound manner compliant with all federal, state, and local regulations. The City generates approximately 8,000 to 9,000 wet tons of biosolids annually, with typical removal of 30 to 32 wet tons per day occurring four to six times weekly during regular operating hours (Monday through Friday, 7:00 AM to 2:00 PM) and weekends as necessary, with all biosolids required to be removed within 24 hours of notification. Qualified contractors must obtain and maintain all permits, complete all required regulatory reporting, provide weekly weight reports (daily preferred), and manage biosolids through reuse or disposal methods in full compliance with applicable laws. Required insurance includes General Liability coverage of $1,000,000 per occurrence/$2,000,000 aggregate, Motor Vehicle Liability insurance of $1,000,000 Combined Single Limit covering all owned, non-owned, and hired vehicles, and Workers' Compensation coverage in compliance with New Hampshire statutes ($100,000/$500,000/$100,000). Bidders must submit unit pricing on a per-wet-ton basis for Class B biosolids, non-Class B biosolids for emergency conditions, and optionally Class A biosolids if the City completes its planned upgrade during the contract term, with pricing based on a $4.00 per gallon diesel fuel baseline and permitted fuel surcharges if market prices exceed this threshold based on the U.S. Department of Energy's weekly diesel price index for the New England region. An optional virtual pre-bid meeting is scheduled for Wednesday, April 29, 2026, at 10:00 AM via Zoom; the deadline for bidder questions is Tuesday, May 5, 2026, at noon, with answers posted by Thursday, May 7, 2026, at 3:00 PM; and bids are due Wednesday, May 13, 2026, at 2:00 PM at the City Hall Purchasing Department with public bid opening at that time. The initial contract term is three years, commencing July 1, 2026, and terminating June 30, 2029, with the City holding discretion to extend for up to three additional one-year terms contingent upon satisfactory performance.

No set-aside designations or restrictions on organizational types responding to this procurement are indicated in the available solicitation materials. The contract will be awarded to the lowest responsive and responsible bidder based on the unit price per wet ton over the three-year period, with an estimated annual quantity of up to 9,000 wet tons provided for bidding purposes only and not guaranteed. No incumbent vendors or current contractors are referenced in the procurement documents. Upon award, all biosolids become the contractor's property, establishing a transfer of ownership responsibility from the City to the selected vendor. The estimated contract value is not explicitly stated in the available documentation; however, potential award values can be estimated based on the annual biosolids volume of 8,000 to 9,000 wet tons and the per-wet-ton pricing structure submitted by bidders. Prospective vendors should note that the contractor assumes full responsibility for all handling, transportation, reuse, and disposal operations in compliance with applicable environmental and regulatory requirements.
