Sanitation District 1, or SD1, the public agency responsible for sewer management in much of the region, recently began using trench-less technology to repair sewer pipes, according to a recent press release from the agency.
“SD1 began implementing this method last year on specific regional sewer projects and the District estimates average cost savings of $2,000 to $5,000 per project compared to conventional repair methods,” according to the release.
The technology employs a flexible epoxy that technicians insert from manhole openings. The epoxy moves through a damaged pipe, molding to its shape before being allowed to harden.
This method of repair allows the district to make repairs without digging trenches. It also enables technicians to make repairs in a few hours, compared to the several days it takes when using older repair methods. The agency hopes to train more workers on this technology moving forward, which they say will do more to reduce costs and increase efficiency.
