Non-Metallic Main Leak Detection (Plastic/HDPE Pipes)

The contract seeks specialized services to detect leaks in non-metallic water mains, including HDPE and PVC pipes, which pose unique challenges due to their low acoustic conductivity and inability to respond to traditional acoustic leak detection methods. Contractors must employ advanced techniques such as step-testing, gas tracing, or high-sensitivity correlators designed specifically for plastic piping systems to accurately identify and locate leaks without invasive excavation. The work is tied to municipal water infrastructure in Salem, Massachusetts, with performance expected at the location indicated by Washington Street, Salem, ZIP code 01970. This is a subcontract opportunity posted under NAICS code 541380, indicating engineering services, and is issued by the Massachusetts agency COSPD - Purchasing. The solicitation was made available on June 17, 2026, with all proposals due by July 9, 2026, at 4:00 PM. While no set-aside designation or point of contact is specified, interested parties must respond through the provided link and be prepared to demonstrate technical expertise in plastic pipeline leak detection, equipment validation, and proven experience with similar infrastructure in municipal water systems. The nature of the work requires precision, specialized tools, and adherence to standards ensuring minimal disruption to water service and public infrastructure.
