Yorkshire Water expects to see savings totalling £1.25 million over five years with a “no dig” gravity-fed sewer lining system.
It said the technology, developed by Axalta Coating Systems, can be applied without having to dig up the road surface and replace it.
It consists of a carbon fibre spray lining application that rapidly sets to create a “pipe within a pipe”, resulting in a 2mm thick extra layer that protects against groundwater infiltration.
Project Manager Mark Gregory said: “We have previously carried out successful trials with this technology on our water mains and sewer but this is a world first in terms of using it specifically for gravity-fed sewers. The spray liner has provided itself to be a highly cost-effective and innovative way to renew ageing infrastructure.
“By applying this technology, we will substantially reduce the risk of failure to our ageing underground assets and also improve the lifespan by 50 years.”
