LAMP (self-propelled Lateral and Mainline Probe)
The LAMP system has been extensively used since 2001. It is an added
module that attaches to a mainline CCTV camera unit which allows for
the insertion of a small camera into the lateral. Hydromax USA's lamp
systems are capable of viewing in excess of 70 feet into the sewer
lateral from a mainline launch.
The lateral inspection camera can also have a separate sonde attached to it for approximate location of the laterals. This location can give guidance to utility crews when making repairs or replacement of the lateral service or in event those other construction activities could interfere with the lateral line.
The LAMP system have been extensively used to determine if HDD (Horizontal Directional Drilling) has intercepted or damaged a lateral. This is especially useful when natural gas lines are being installed.
A typical LAMP picture in picture feature enables the operator to
monitor the pan and tilt inspection of the mainline and launch a camera
from the mainline to inspect the adjacent lateral service. LAMP can
also be used for identifying infiltration and inflow, solids accumulation,
root infiltration, pipe defects, and the structural condition of the
lateral services while also capturing the same from information the
mainline sewers.
LAMP can be used to verify rehabilitation processes of lateral sewers such as relining and spot repairs.
Enhanced Public Safety
LAMP systems are used extensively for determination of cross bores that result from HDD (horizontal directional drilling) operations. The process is best used when a pre-inspection and a post-inspection is performed.
Natural gas supply lines that penetrate a sewer are subject to causing backups in lines. A typical cleaning method is to use powered root cutters such as used by a Roto Rooter™ service technician. Explosions and death can result from cut plastic gas lines as a result.
