R-2482 - Dartmouth & Tower Transmission Main Condition Assessment

This project will engage a specialized technology provider to perform a high-resolution condition assessment and leak detection survey. The inspection tool must be deployable through a maximum 2-inch opening and capable of completing approximately 2,000 feet of internal inspection. The tool must provide closed-circuit television (CCTV) footage for visual inspection, along with precise, above-ground leak location correlation. The inspection will begin with the 42-inch bar-wrapped concrete pipe. If no leak is found, the 24” ductile iron main will also be inspected to ensure the source the surfacing leak is identified. Deliverables will include detailed maps, video, survey data, and condition assessment findings to guide future asset management decisions.
