The removal of exemptions from the licensing regime of quarry dewatering will potentially be problematic to the industry. Whereas it has always been intended that this process will be 'light touch', situations will arise where difficulties in being able to remove water from quarry workings may be problematic.
The restoration of mineral workings provides great potential to create specific habitats which can enhance ecological value. Water features are frequently key components of such schemes. Hafren Water has been involved with the optimisation of the potential benefits of water in restorations at numerous sites throughout the UK. This frequently involves predicting future water levels and designing water management schemes to ensure that optimal water conditions exist for target species or habitats. We have provided hydrological input to large reed bed creation schemes at former sand and gravel sites, advised on final water levels and devised long-term water management plans at numerous restored quarry sites.
