The process in which the structural integrity is restored by shotcreting the interior walls of the manhole. After the structural integrity is restored the walls are protected with 100% solids epoxy to protect them from harsh hydrogen sulfide attack.
LIFT STATION REHAB
A cost effective solution to replacing the entire lift station. Lift stations in need of rehabilitation may experience issues with electrical control panels, motor and pumping systems, broken or cracked pipes and in severe cases; excessive corrosion in wet wells or junction box. In extreme cases the lift station may need to be upgraded to better suit the increase of demands on the system.
closed circuit television (cctv)
CCTV is used to inspect the insides of pipes via the use of robotic rovers with mounted cameras. These mechanical robots may also be equipped with repairing tools and technology.
A trenchless means of replacing a pipe. Pipe bursting fractures the existing, deteriorating pipe and drives its pieces into the ground around it by internal mechanical force, while pulling the replacement pipe into place. There is no need to remove existing pipe. There is no need for a separate step to install the new pipe and there is no need to drill a new bore.
Cured In Place Pipe (CIPP)
One of several trenchless rehabilitation methods used to repair existing pipelines. CIPP is a jointless seamless, pipe-within-a-pipe with the capability to rehabilitate pipes ranging in diameter from 0.1 to 2.8 meters (4-110 inches).
An important part of the pipe rehabilitation process. Teams working on pipe rehabilitation install temporary bypass pumping systems to transfer sewage and water flow, which helps maintain uninterrupted services for local businesses and residents while maintenance for work is occurring.
