Sludge Gravity Thickener Pump

The Town of Killingly, Connecticut is soliciting sealed proposals for the furnishing and delivery of one new sludge gravity thickener pump for use at the Town's Water Pollution Control Facility located at 31 Wauregan Road. The procurement is limited to equipment supply and delivery only, with all installation, piping, electrical work, alignment, startup, and commissioning to be performed by others. The basis of design is a SEEPEX Model BN35-6LS progressive cavity pump; however, qualified bidders may propose approved equal positive displacement pumps, including rotary lobe pumps or other proven designs, provided they meet or exceed the basis-of-design pump in all performance, material, maintenance, and documentation respects. The equipment must be capable of handling flow rates from 5 to greater than 75 gallons per minute, solids concentrations from 0.5% to 6.0% by weight, and continuous 24/7 operation, with a documented operating history of not less than three years in comparable municipal wastewater sludge service. Sealed bids must be received by 10:00 AM EDT on Friday, June 19, 2026, at the Office of the Town Engineer, with public opening and reading of bids immediately following the deadline. The vendor question and answer period is open from May 13, 2026 at 12:30 PM EDT through June 9, 2026 at 12:30 PM EDT. Equipment delivery is required within 120 calendar days of the Notice to Proceed, and the initial contract term is 150 consecutive calendar days commencing on the first day following full execution of the contract.

Bidders must demonstrate a minimum of five years of experience supplying positive displacement pumps for municipal wastewater or industrial sludge applications and provide a minimum of three municipal references. A 10% bid bond or certified check must accompany all proposals, and bidders must submit a non-collusion affidavit. The solicitation does not indicate any specific set-aside designations for disadvantaged enterprises or restrictions on organizational type, and all qualified pump manufacturers, suppliers, and contractors are eligible to respond. Payment is due 100% upon delivery of the pump to the Town-designated facility location, satisfactory initial inspection, and final acceptance by the Town, including receipt and approval of all required closeout documentation. No bonding is required for project performance, and the Town is exempt from sales tax. The solicitation does not provide an estimated total contract value; however, pricing shall be submitted on the provided bid form with costs stated in both words and numerals. The Town reserves the right to reject any or all bids and to award the contract to the lowest responsible and qualified bidder as determined solely by the Town in its best interests. All spare parts must be readily available within North America with lead times not exceeding 10 business days for in-stock items or 30 calendar days for regularly manufactured items, and the manufacturer must guarantee availability of normal wear parts for a minimum of ten years from the date of Town final acceptance.
