Rehabilitating an 1897 Water Main
Without Disruption

Award-Winning Project

Challenge

As part of the City’s multi-year rehabilitation plan, they had to update a water main that was built in 1897. There were no as-built drawings of the main, and it passed underneath several businesses, a double row of railroad tracks, a regional trail and the Menomonie River.

Solution

The project used trenchless technology to rehabilitate the water pipe with a Class IV fully structural cured-in-place pipe (PIPP) liner. The use of the trenchless technology allowed the process to go on without disrupting area businesses or digging up the street.

Features

  • 300 feet of 12-inch water main pipe was rehabilitated
  • Class IV cured-in-place pipe (CIPP) liner will last another 70+ years
  • Assessment using live underwater cameras
