Water law comprises the federal and state standards that relate to the order and management of surface waters and groundwater. In principle, water bodies can only be managed with official permission. There is no entitlement to such a permit.
Water law regulates, among other things, the requirements for structures in, under or above surface waters and for wastewater treatment plants. It regulates prohibitions and restrictions in watercourse margins, flood plains and water protection areas, as well as notification requirements for boreholes affecting groundwater. It also determines the content and scope of the obligation to maintain water bodies.
