Ladybower Reservoir | Scour Valves Refurbishment | Blackhall Engineering

Ladybower Reservoir is a large Y-shaped reservoir, originally built in the period between 1935 and 1943 and is located in the Upper Derwent Valley, at the heart of the Peak District National Park. The capacity of the reservoir is 27 million cubic meters and was officially opened by King George VI on 24th September 1945.

In 2018, during statuary inspections concerns were raised by the reservoir's panel engineer that the Larner-Johnson scour Needle valves in the dam valve tower were not shutting off correctly. The Blackhall valvologists were called in to inspect and diagnose the problem and conduct feasibility studies to provide the best possible refurbishment options in 2018.
