REPLACEMENT OF IN-SERVICE WATER MAIN VALVES & FITTINGS ON MAIN ST

This contract entails the replacement of approximately 80 in-service water main valves along the Town-owned section of Main Street (Route 83) in Manchester, Connecticut, primarily within the downtown area between Hartford Road and US Route 6/44 (Center Street). The work involves removing about 30 existing 16-inch butterfly valves and 50 gate valves of various sizes ranging from 4 to 12 inches, and replacing them with new resilient wedge gate valves. Additionally, three spot valve replacement locations are included along the Connecticut Department of Transportation-owned Route 83 right of way near the S Main Street bridge over I-384 to ensure proper isolation of the water main crossing the bridge. The valves targeted for replacement have either failed or reached the end of their service life and require upgrade as part of standard system maintenance. Beyond valve replacement, the project requires ancillary tasks such as installation of resilient wedge gate valves at new sites, replacement of several water main segments with ductile iron pipe matching valve sizes from 4 to 16 inches, and both temporary and permanent pavement repairs along the affected roadways. Traffic control measures will be implemented to maintain safety and minimize disruption during construction. The project schedule stipulates completion within 150 working days. Administrative details include solicitation number 25/26-35 with a response deadline of March 2, 2026. The managing agency is the Town of Manchester’s Engineering Department, with primary contacts listed as John DiBiasi, Assistant Town Engineer, and Cora Narracci, Purchasing Agent. The contract encompasses all necessary work to restore and maintain infrastructure reliability on a vital municipal thoroughfare.
