City to use cured-in-place pipelining for Cheshire Ditch sewer rehab; lining work expected next week
Loading...
Summary
Staff explained the trenchless CIPP process to the committee, said lining typically cures in about four hours, and said the contractor expects to start work at Cheshire Ditch at the end of next week.
Carla described the cured-in-place pipe (CIPP) lining technology the city will use for the Cheshire Ditch sanitary sewer rehab.
She explained the trenchless process and materials: a flat liner (felt material impregnated with resin) is inverted into the existing pipe, hot air is used to cure the resin and the cured liner becomes the new pipe interior. "The chemical process then cures the pipe. It typically takes at least 4 hours for this material to cure," she said, and noted the technique is considered 'no dig' trenchless rehabilitation.
Carla said the contractor (Performance Pipeline, as named in supporting materials) plans to begin lining at the end of next week and continue into the following week; she invited committee members to observe the process if they wish.
No budget figures or contract award details were provided in the Services Committee discussion; Carla said dates are contingent on contractor scheduling and she will share timing and contact details with committee members.
