Collection System Flow Monitoring Program

The City of Nashua, New Hampshire, Division of Public Works, is issuing an Invitation for Bids (IFB0298-061026) to procure flow monitoring services for its municipal wastewater collection system. The procurement requires qualified independent contractors to supply, install, and maintain seventeen flow monitors and three rain gauges at specified locations throughout the collection system, with deliverables including real-time monitoring capabilities, remote notifications via email and text message, and monthly reporting accessible through a secure web-based portal. Successful contractors must demonstrate experience with similar-sized municipal projects, provide certificates of insurance (General Liability $1,000,000 per occurrence/$2,000,000 aggregate, Motor Vehicle Liability $1,000,000 combined single limit, and Workers' Compensation coverage), and submit references from five comparable communities along with performance letters from previous municipal projects. The contractor must retain equipment ownership, maintain a secure, daily-backed-up server for 24/7 data accessibility through a password-protected website, and provide initial setup, installation, optimal sensor location determination, training, and calibration services. Key deadlines include a mandatory pre-bid meeting on May 27, 2026, at 10:00 AM at the Wastewater Treatment Facility (2 Sawmill Road, Nashua, NH) with virtual Zoom participation available, a written inquiry deadline of June 2, 2026, at noon with responses posted by June 4, 2026, at 2:00 PM, and sealed bid submissions due by 2:00 PM on June 10, 2026, to the City Hall Purchasing Department. Contract award will be made to the lowest responsive and responsible bidder based on demonstrated experience, organizational capacity, technical qualifications, and cost control, with an initial three-year term commencing July 1, 2026, through June 30, 2029, and the City retaining discretionary rights to extend for up to two additional one-year terms contingent upon satisfactory performance and budget appropriations.

The procurement documents do not specify any set-aside designations or restrictions limiting responses to particular categories of organizations, such as disadvantaged enterprises or minority-owned businesses, indicating the opportunity is open to all qualified independent contractors meeting the stated requirements. No incumbent vendors or current contractors are identified in the available procurement materials. The compensation structure consists of three distinct line items: a lump-sum amount for initial setup, installation, equipment optimization, training, and calibration; a monthly maintenance amount for the initial three-year contract period; and supplemental optional pricing for potential fourth and fifth calendar year maintenance extensions, though specific budget ranges or award values are not disclosed in the published solicitation documents. All bids are binding for ninety days following the bid opening date of June 10, 2026, and bidders must submit non-collusion affidavits and identify any subcontractors representing five percent or more of the bid value as part of their proposal submissions.
