Priority groundwater area Indicative plan V 1.1

In priority groundwater areas of cantonal importance, which are set out in the indicative plan, interests of groundwater management take precedence. Therefore, no new gravel mining areas are allowed on these areas. The extent of the priority groundwater areas of cantonal importance is determined on the basis of hydrogeological criteria. The Indicative Plan 2011 Overall Map was adopted by the Grand Council on 20 September 2011.
