This project consisted of the CIPP rehabilitation of approximately 600 residential sewer laterals from the existing cleanout to the City main. The full length of over 9,000m of sewer first had to be televised, cleaned, and prepped before the liner installation.
The most common defect in lateral sewers is the presence of roots, which can easily be removed by using our 15,000-psi high-pressure water unit. When further investigation of the lateral was required, CWW depended on its LAMP (Lateral and Mainline Probe) camera, which provides total inspection of the lateral from the main sewer.
CWW uses a felt liner impregnated with epoxy resin, which is then inverted with air and cured with hot water. The rehabilitation of sewer laterals by CIPP is a prudent and cost-effective alternative to the conventional dig-and-replace method, as costs associated with the reinstatement of existing landscaping, trees, utilities and roadways is eliminated. Further, our experienced technicians often complete the entire CIPP process in less than 5 hours.
CWW reinstated weeping tile connections internally through the use of a robotic cutter. It is also important to note that the CIPP process remains unaffected by colder weather, which is another significant advantage over traditional excavation methods.
