Walham

From Wikipedia, the free encyclopedia

Walham is a village, situated north of Gloucester, on the banks of the River Severn, just off the A40 road.

A National Grid switching centre, providing power to half a million homes and the Government Communications Headquarters (GCHQ), is situated at Walham. Walham substation came to prominence in July 2007, when it was threatened by a flood. The fire service and military stopped the flood waters two inches below the height at which the plant would flood. This struggle with nature was dubbed the "Battle for Walham" in national newspapers.
