Time to Upgrade the Sewer Lines: St. Paul Starts Repair Work

st-paul-sewer st-paul-sewer

For many cities, officials don’t know there’s a problem with its sewer lines until an issue arises like overflow or collapsed line causing a sinkhole. St. Paul experienced the latter and thus began the tedious repairs to its sewer lines.

Rehabilitating and repairing sewer lines began last week in St. Paul. The work will rehabilitate sewer lines that have been shown through recent inspections to have significant corrosion and issues with structural integrity.

City officials began doing inspections in 2014 after a portion of a sewer line collapsed and caused a sinkhole. Following the emergency repairs, all sewer lines were inspected and plans for rehabilitation were put into place.

Since then, repairs have been in the process and all work has been done using the cured-in-place-pipe (CIPP) method. For those who don’t know, the CIPP process is a resin-saturated felt tube made of polyester, fiberglass cloth or a number of other materials suitable for resin impregnation, is inverted or pulled into a damaged pipe. It is usually done from the upstream access point (manhole or excavation). Little to no digging is involved in this trenchless process, making for a potentially more cost-effective and less disruptive method than traditional “dig and replace” pipe repair methods.

According to the project timeline, all work is scheduled to be completed by June 2020 with some work estimated to be finished by the end of summer 2019.
