Frankley Water Treatment Plant is a major water supply source for Birmingham, its environs and the West Midlands region of England. It serves industrial users and 1.3 million domestic customers.

The Birmingham Resilience Project comprised 26 km of 1000-mm-diameter steel transmission main from the River Severn to Frankley Reservoir and Water Treatment Plant, 120,000 m³/day river intake and high lift pumping station on the River Severn and a 2000 m³ reservoir.

We were responsible for delivering all civil and structural design elements, including eight major trenchless crossings and 22 minor crossings. The major crossings included a motorway crossing, A-road crossings and a trenchless drive under protected woodland. Our design scope included installing the parent pipe and shaft restraints, annulus grouting, jacking walls and supplying temporary work designs.
