Flood Control: Gloucestershire

Volume 475: debated on Wednesday 7 May 2008

To ask the Secretary of State for Environment, Food and Rural Affairs what analysis of critical infrastructure facilities has been undertaken in respect of Gloucestershire since July 2007; what additional protection has been put in place as a result; and what consideration has been given to the relocation of critical infrastructure.

During the Gloucestershire floods, electricity supplies were disrupted due to flooding of the Castlemeads electricity distribution substation. In addition, the larger Walham electricity transmission substation required urgent flood protection measures to be carried out to prevent the site from being flooded. Both of these substations now have permanent flood protection barriers in place.

A review into the resilience of electricity substations to flooding was initiated by the Energy Minister. It is being led by the Energy Networks Association with support from network owners, BERR, Ofgem and the Environment Agency. This review has made contributions to Sir Michael Pitt’s review into learning lessons from the 2007 floods and has developed a framework for assessing flood risk and mitigation measures that will be used to assess the situation at each of the major electricity substations during the remainder of 2008.

Severn Trent Water has been developing plans to secure alternative piped water supplies to Gloucestershire in the event of losing either Mythe or Mitcheldean Water Treatment Works. These plans are not limited to providing additional flood protection at the works and include such things as new pumping stations and improved interconnectivity between the works at Mythe and Strensham. The company presented outline proposals to Gloucestershire Overview and Scrutiny Management committee on 31 March 2008.
