Protection des prises d'eau de surface destinées à la production d'eau potable

Jean Carré 1 
Abstract : In order to protect surface water intakes of accidental or point pollutions, the proposed strategy associates classical perimeters comparable to a static protection and a security of intakes corresponding to a dynamic protection. The longitudinal expansion of the close protection perimeter intended to maintain water quality near the intake, must offer 2 hours delay before the pollution reaches it. Laterally, the close protection perimeter is subdivided in a buffer zone receiving the overland flow and in an additional zone allowing a control of activities. The implementation of this strategy, guarantor of a greater efficiency of the protection, leads to limit the expansion of perimeters and facilitate the accomplishment of the procedures. Among security measures; the interconnexions and the research of help resources must be privileged. The creation of storage basin, well adapted to big collectivities, is not always possible. By their huge cost, warning stations are adapted to big intakes located downstream of urban or industrial areas. Their layout point and the choice of continuous analysed parameters must aim to a detailed study so that these stations do not constitute a false security.
