RFP027-21 Sewer Relining

The City of Meriden DPU: Sewer Division is seeking proposals from qualified contractors to provide comprehensive maintenance, lining, and re-lining services for the City's sewer mains and manholes.

The City is seeking a highly qualified and experienced partner capable of fulfilling all functional requirements outlined in this RFP, with the scalability to integrate future enhancements. The ideal firm will feature a team of local government experts dedicated to achieving the City's vision while ensuring uninterrupted service to our residents. The successful firm must have lined over 3,000,000 feet of pipe, of which 250,000 feet must have been 24” or larger diameter pipe, and must self-perform 100% of work.

Meriden is located at the Crossroads of Connecticut, with roughly 60,000 residents and is situated midway between the cities of New Haven and Hartford. The City has a Public Utility Dept. that is comprised of a Water Division with three subsets, distribution, filtration, and metering as well as a Water Pollution Control Facility (WPCF), which operates a sewage treatment facility as well as an extensive collection system.

The Sewage Treatment Plant is a State of CT NPDES permitted facility and it is located at the Southwest end of the city. The plant is designed to treat 11.6 million gallons per day [MGD] utilizing a modified 5-step BARDENFLO system to remove Nitrogen and Phosphorous as well as Biological Oxygen Demand [BOD]. This system also incorporates a Parkson Dynasand system for low-level phosphorous removal and tertiary polishing before releasing its effluent into the Quinnipiac River.

The sanitary collection system consists of approximately 210 miles of sewer lines, utility owned trunks, interceptors, mains, three pump stations, force mains, two existing siphons, one future siphon, and manholes located in both City and State owned streets, as well as utility right of ways. The customer owns all building laterals from the building up to and including the ‘Y’ connection at the main.

Known materials used in the collection system include: vitrified clay [VC], brick, asbestos concrete pipe [ACP], transite, cement [CP], cast iron [CIP], ductile iron [DIP], and PVC. Known sizes of these pipes include: 8”, 10”, 12”, 15”, 18”, 24”, 27”, 30”, 36”, 48” round pipe, along with some elliptical.

From time to time the City may request scoping out similar repair/lining work for additional needs, such as storm pipe repair and/or lining, (current inventory believed to range from 8” to 54”). Any additional unit prices for goods and services such as this, after mutual agreement on a fair and reasonable price, shall be added to the Contract via formal Change Order for the remainder of the contract term.
