Sewer relining begins in Missouri

A project to rehabilitate ageing sewers, maintenance holes and lateral connections has launched in Missouri, US.

The City of Columbia’s Sewer Utility has contracted Ace Pipe Cleaning to reline ageing sewer lines as part of its 2018 Inflow and Infiltration Rehabilitation Project, which has an estimated investment of US$2.7 million.

The project will rehabilitate approximately 16.8 km of sewer line using cured-in-place pipe using steam to expand and cure the liner in the host pipe, as well as rehabilitating 275 maintenance holes and 300 lateral connections.

Due to the complexity and age of the city’s 1,047 km gravity sewer system, the utility undertakes sewer modelling to plan rehabilitation projects on a priority basis to prevent inflow and infiltration issues.

An interested parties meeting for the project initially took place in December 2017, with the public hearing following in February 2018.

The project is anticipated to be completed, weather permitting, in August 2019.
