Ice Pigging negates replacement of rising sewer main

Nov 2021

Eight years ago Severn Trent was preparing for implementation of a capital replacement project of a rising main until they found out about our services. The Ice Pigging team serviced the main and increased the flow enough to make the replacement project unnecessary, not only saving money for our client, but also a significant reduction in CO2 emissions.

This year, the main has been cleaned again with Ice Pigging – improving the flow from 0.8 l/sec to 1.5 l/sec (88% improvement), which should keep the main running well for another eight years.
