French Drinking Water Distribution Networks by Commune (Hub'Eau)

hubeau/drinking-water-networks

Lists the drinking-water distribution units (UDI networks) that supply a French commune, found by its INSEE code: network code and name, the part of the commune it serves, the date supply began and the year. A large commune has many networks. This names the networks only; it does not return water analysis results. An unknown code returns an empty list. Data from Hub'Eau (sanitary control produced by the Ministry of Solidarities and Health), Licence Ouverte Etalab; served by Eden Engine; not an official Hub'Eau product.
