Keswick WwTW, Cumbria

Flood alleviation measures are required for this project

ByrneLooby designed the 12.5m deep shaft required to enable the construction of a new pumping tank in Keswick, Cumbria. Two floods in the last decade devastated Keswick and as part of the flood alleviation measures a large new underground pumping station was built to increase sewer capacity and eliminate UIDs.

Our design to enable the provision of this piece of infrastructure consisted of a 15m diameter shaft to allow a dig to 12.5m below ground level. We designed the shaft to support itself in ring compression eliminating the need for our client to incorporate expensive propping and significantly increasing the pace of the construction programme.   

Scope of project

  • Design of a 15m circular shaft to allow a dig to 12.5m below ground.
  • The shaft was designed to support itself in ring compression thereby eliminating the need for expensive propping and speeding up construction for our client.
  • Part of the flood alleviation works in the flood prone Cumbria area.
