Lateral assessment is a vital component in the inspection, maintenance and renovation of collections systems. The CCTV Inspection is generally done using one of two methods; inserting a small diameter camera designed for 3-inch to 6-inch pipelines via a clean-out towards the mainline, or using a robotic mainline/lateral inspection camera system that launches a camera from the mainline connection up towards the building connection/clean-out. Newer equipment now has the capability of panning and tilting the lateral camera while inspecting lateral pipes; as well as laser profiling the lateral pipe ensuring the right sized liner is installed during lateral pipe renewal projects.
Assessment data gathered by either of these two methods (typically in a standardized format, such as LACP®, to merge with mainline assessment data) is used to determine the need and/or appropriate methods for long-term successful renovation of the collection system.
The RehabZone would not be possible without the generous contributions of industry leaders, companies and organizations that share UIC’s vision to set standards for the assessment, maintenance and rehabilitation of underground infrastructure and to assure the continued acceptance and growth of trenchless technologies.
