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.
