Foss Barrier

  • Client: The Environment Agency
  • Delivered by: JBA Bentley
  • Location: York, North Yorkshire
  • Value: £8m

Built in 1987 in response to severe flooding five years earlier, the Foss Barrier forms an important part of the flood defences of York. A gate can be closed to prevent rising waters in the River Ouse from backing up into the River Foss and flooding parts of the city.

In December 2015 floods hit York once again, with waters rising into the electrical switch room for the incoming mains supply, rendering it inoperable.

After significant involvement in the emergency response to the floods we were then engaged by the Environment Agency to deliver permanent upgrade works on site.

At the core of these works is an upgrade to the Foss Barrier Pumping Station where we are increasing the capacity of the pumping station through the installation of eight new pumps and associated MEICA equipment. Each pump weighs 6.5 tonnes and is capable of pumping 6m³/second.

The upgraded equipment will be housed within an extension to the existing building that will lift all critical equipment above the flood zone. To facilitate this, all equipment has been temporarily located on a purpose built platform.

Foss Barier was selected to feature in the 2018 UK Water Projects publication further information can be found here.
