In 1986, Torr Works Quarry was granted planning permission to extract stone beneath the natural water table. This permission resulted in the introduction of an extensive water management scheme. Modified over the years this scheme now includes:
Construction of a 425,000,000 litre external reservoir was completed in 2003. Designed to meet the quarry’s augmentation requirements for its lifetime, it has also provided ideal habitat for numerous wildfowl including the little ringed plover.
In 2012, permission was granted to deepen the existing quarry area, releasing a further 115 million tonnes of stone. This will lower the water table by approximately 112 metres to be 3 metres above sea level. Monitoring data collected over more than 25 years and the ability to demonstrate an effective water management scheme were key aspects in obtaining the support of the Environment Agency for this major application.
