Abstract
A method is provided for the installation of varied sewer rehabilitation lining materials within an existing sewer while conveying sewage flow through an internal bypass contained on a sled that applies the rehabilitation materials, thus eliminating the need for an expensive, intrusive above grade external bypass. The apparatus is compatible with the various rehabilitation materials, technologies and methodologies currently available in the industry. The method and apparatus can be utilized to restore the original structural integrity of a sewer pipe or to provide a corrosion barrier. Multiple and varied rehabilitation materials (including but not limited to epoxy, geopolymer, mortar, cement, etc.) can be applied using the same apparatus. The apparatus can also be utilized to clean and televise the sewer prior to and during the rehabilitation process.
