UK substation gets flood defences backup

April 18, 2018

UK civil engineering firm Barhale is completing a major project to protect a National Grid substation from potential flooding.


The GBP1.3 million ($1.8m) ‘resistance and resilience’ project was ordered after the 132kV/275kV/400kV Melksham substation in Wiltshire, was identified in a review as being at risk of flooding “from a 1 in 200 and 1 in 1,000-year event”.


The review was conducted following extensive flooding in the UK in 2017. Construction on the project began last June (see photo) and is scheduled to finish on 20 April 2018.


Barhale said the review “recognised the significant impact the widespread loss of electricity can cause”. The review also noted a “loss of power caused fear and distress to the public and could have serious health consequences”.


Abdi Rahman, site agent for Barhale’s southern office, said the company’s extensive infrastructure construction included designing and building an 81-metre concrete flood wall along the northern side of the main access road to divert water away from the substation.
