About this file
This is a set of design drawings for pipe modification work at the Town of Stratford Water Pollution Control Facility (WPCF) in Stratford, Connecticut, issued for bidding in September 2026. The project involves dewatering, cleaning, ground water control, CCTV inspection, and Cured-in-Place (CIPP) lining of approximately 225 linear feet of 54-inch corrugated metal pipe (CMP) stormwater pipe and approximately 105 linear feet of 12-inch reinforced concrete pipe (RCP) stormwater pipe located at Diversion Chamber C. The work scope includes removal and disposal of sediment (estimated 12-24 inches) from the existing pipe, retrieval of a jetter and cable stuck approximately 70 feet from the Diversion Chamber C inlet, identification and excavation of a buried 12-inch RCP inlet headwall, and proper plugging of the pipe to prevent river water or wetland flow from entering during construction. A prebid meeting is scheduled for September 29, 2026, at 10:00 AM. Contractor access will utilize existing access points at Diversion Chamber C and the catch basin for liner insertion and termination.
The lining work must occur during dry weather and low river conditions, with the contractor responsible for monitoring rainfall and river levels throughout installation, curing, and testing phases. The contractor is responsible for all site safety, utility support and protection, traffic control, erosion control protocols, and compliance with applicable local, state, and federal regulations. Ground water was observed 5 feet below grade, and the contractor must identify and control groundwater infiltration that may interfere with installation or curing. All construction-related waste materials and debris must be removed and disposed of in accordance with applicable regulations. The drawings note that a non-operational sluice gate exists on the Chamber C structure and should not be relied upon for work execution. Electronic bid submission is prohibited.
