Costain wins Northumberland water main project

Costain has secured its first project within a competitive tender framework with Northumbrian Water, to construct a duplicate rail crossing in Northumberland.

The scheme will provide back up to an existing water main and will reduce the likelihood of a burst water main underneath the East Coast Main Line, which would require permission from Network Rail to access the land in order to repair it, as well as any potential compensation for any disruption to the railway.

The work involves constructing a tunnel 8m deep and beneath the railway line, to install a steel sleeve which will house a 450mm diameter polyethylene pressure main.

The existing 300mm under-track crossing will also be relined with a High Pressure Polyethylene liner. Trenchless technology will be used to carry out the work.
