The drinking water distributors in Ile de France regularly have to face river floods. In the last decades heavy floods were observed (in 1955, 1982, 1988...) but thanks to protective measures implemented during this period, no inconvenience to the consumers was recorded.
Nevertheless, some facilities would be definitely flooded in case of a major flood like that of 1910. With, as a result, a noticeable reduction of the potential of water production capacity.
Subsequently, in addition to the direct impact of the submersion of the facilities, the water distributors would also have to take into account the resulting adverse effect on the economical and physical environment of the water treatment plants; this would increase their vulnerability (raw water quality, power supply, reagents supply...).
These different aspects are discussed here.
