Legacy Cross Bore Inspection
Horizontal directional drilling began in the 1970’s. Since then it is unknown how many cross-bores truly exist. A cross-bore happens when the utility installed through trenchless technology intersects an existing utility, compromising the integrity of either utility. This can be dangerous with any utility, but especially when a gas utility is installed through a sewer line. Unlike with water or power, it is usually unknown when a sewer line is cross-bored unless it has been inspected. This would lead to the sewer backing up and having a plumber attempt to remove the clog with a cutting tool.
Why yearly inspection is necessary
Due to the unknown number or cross-bores that exist, best practices and safest methods is to inspect any sewer lateral that could have been installed through trenchless technology. Hundreds of cross-bores are being found across the country each year.
Our equipment can inspect from the mainline or from inside the building. Preferred method is to visually inspect the mainline first for any obstructions. Then on the way back we inspect the laterals from the main. If we are unsuccessful in being able to fully inspect the lateral, a smaller tool can be brought inside the building to inspect from the inside out. After the inspection is complete we can save the information onto an electric device for future reference. Please contact us for further information.
