Summer Sewer Lining Projects

Summer is just around the corner, and that means Marion Utilities will be out continuing work to reline old sewer pipes throughout the city.

In May, the utility will award a substantial sewer rehabilitation project to reline old sewer pipes with a C.I.P.P. (or Cured in Place Pipe) process. In this process, resin is pumped into a pipe-shaped bag made of linen and fiberglass cloth. The bag is inserted into the sewer line and inverted, and then pumped up like a balloon and cured using hot water or steam. The resin takes the shape of the sewer main, basically creating a brand-new sewer line without digging up roads and installing new pipe. The new liner helps eliminate root problems and ground water infiltration.

This lining project will rehabilitate approximately 5,900 feet of sewer main and is expected to be completed in September of 2021.
