Abstract:
In the context of the self supervision of drinking water distribution systems, network managers have to carry out regular sampling campaigns. These samplings give a selective overview of quality but may suffer from a lack of representativity. Considering that a rational approach of the choice of sampling sites would improve the control of the quality in the network, the CIRSEE has developed a new strategy of selection of sampling sites. This strategy is based on an algorithm derived from a publication of Lee and Deininger. Modeling of the hydraulic behavior of the network is a compulsory step to street optimal sampling points. A covering matrix, deduced from PiccoloΒ® hydraulics modeling (developed by SAFEGE), defines the link between each network node. Afterwards, the algorithm selects the most representative points (for sampling or on line monitoring) in terms of consumption and of water degradation (function of pipe diameter and water retention time).
