Sewage, Sondes and Section-82
Section-82 of the Environment Act 2021 requires water and sewerage companies in England to install continuous water quality monitoring (CWQM) upstream and downstream of every storm overflow and sewage treatment works discharge. This requires the widespread deployment of multi parameter water quality sondes to measure key water quality parameters in real time. The CWQM programme will provide a widescale overview on the health of England’s rivers, however its implementation comes with several challenges for WaSCs.
