DBGT10K — Treatment of the water supply network

It corresponds to the route of the conduct in its different specifications within the network, i.e. with the distinction between the main sections, the collective sections and those of domestic connection. Each ‘drinking water supply network’ is characterised by the type or types of supply. The survey of the pipelines, at the aerophotogrammetric, for the underground sections, generally refers to what can be observed at the wells: it is therefore appropriate to classify the route for these non-visible portions with information that gives reason for the reliability of the interpolated position (even possibly on the basis of additional sources compared to the relevant data of the wells).
