Algal blooms in reservoirs can cause costly physical disruption of treatment processes and severe problems with water supplied in relation to cyanotoxins, taste and odour. To avoid these problems companies need to manage reservoirs to minimise the potential for algal blooms and ensure that effective treatment is in place. There are costs associated with both of these and there is scope to optimise them. Costs associated with prevention of blooms could be offset against savings of costs of, for example, for more frequent regeneration of GAC, which could be around £1000 per day for a 100 Ml/d works.
This project will provide detailed guidance for achieving the best balance between reservoir management and treatment measures to safeguard supplies.
