A special monitoring system is helping protect water quality on the Somerset Levels and Moors where the dredging operation is taking place. The system, supplied by OTT Hydrometry and installed by Wavelength Environmental, is designed to protect the river ecology by issuing email alerts if water quality deteriorates beyond pre-set conditions. Any such alerts is immediately relayed to the project team so an assessment of conditions can be undertaken, and working practices reviewed and continued. In recent years, an accumulation of sediment has narrowed the river channel and this is believed to be just one of the reasons for the severe flooding that took place.
