Securing water catchment sites is essential to prevent human and animal health risk and reduce the potential negative economic impacts on the water supply chain. A large part of pumping facilities being located at lake reservoirs, the exposition to algal blooms is a reality due to low water exchange/stirring and run-offs of agricultural and industrial wastes, phenomenon also aggravated by recurrent heat waves events.
Water supply companies are thus confronted to manage this risk and anticipate problems related to water treatment processes and facilities, e.g. filter clogging, reagents extra charge; not to mention the media hype triggered by pathogens proliferations closed to catchment sites.
