Project Overview
Industry: Gas Distribution
Location: Newburgh, N.Y.
Client: Central Hudson Gas and Electric
Business Areas Addressed:
- Water Intrusion of Low Pressure Gas Main
Project Description
Prior to arriving at the job site, utility crews excavated two compact camera entry pits and prepared the main with the necessary fittings and valves. These two camera entry pits would enable ULC crews to inspect the entire length of pipe to locate the blockages and investigate the source of the water intrusion.
Using the patented PRX250 Live Gas Main Inspection Camera System, ULC Technologies’ field crew was able to insert the camera into the live, low pressure main from both entry points, which were approximately 300 ft apart in distance. ULC crews identified the low point where the water was collecting in the pipe. Using a specialized version of our innovative camera system, our crews were able to pinpoint the location of the blockage from above ground – providing the utility with an efficient means of excavating directly over the issue to extract the water.
Internal visual inspection of the gas main enabled ULC crews to follow the trail of water to identify exactly where and how the water was coming into the main, which was located 436 feet away from the blockage. The location of the water intrusion point was also marked on the street surface for efficient repair to resolve the water intrusion issue quickly.
Project Benefits:
- Reduced guesswork through internal identification of blockage and water intrusion point
- Enabled more efficient repair to resolve the issue quickly
- More efficient restoration of gas service
- Avoiding unnecessary excavation and restoration of the street
- Ensured all blockages were identified before utility crews left site
- Eliminated follow up visits due to reoccurring water issues
