Lateral Rehabilitation Mean?
Lateral rehabilitation of sewer lines is the trenchless rehabilitation of lateral sewer lines using methods such as cured-in-place pipe (CIPP), pipe bursting, grouting, and slipping.
After an inspection takes place, the reason for the fault can be ascertained and the best method of lateral rehabilitation determined.
A faulty lateral connection can cause the joint to open and allow infiltration, exfiltration, and the access point for tree root intrusion and soil.
Trenchlesspedia Explains Lateral Rehabilitation
Lateral rehabilitation is started off by cleaning the pipe of debris and conducting a lateral sewer inspection using a lateral launch camera.
Lateral launch cameras are used to inspect lateral lines branching out from the main sewer line. They are capable of inspecting mainline and laterals simultaneously and can inspect mainlines to a distance up to 1000 feet from the entry point and laterals up to 150 feet from the mainline.
The lateral sewers are the pipes that collect wastewater from homes and offices. Branch sewers connecting to various laterals empty into the main sewer.
The lateral sewer line is smaller in diameter than the main sewer and is connected to the sewer main by a wye, saddle, or cut-in-wye connection.
The main sewer collects wastewater from different laterals and branch sewers and delivers it to a trunk sewer, which either carries the water to a treatment plant via gravity or to an interceptor sewer.
