Key legal question
Whether the covering and lowering of drainage manholes on the appellant's land was permissible despite disputed ownership of the drainage system
Extracted holding
The covering was impermissible. The communal drainage authority must have unhindered access to the entire drainage system for monitoring and maintenance, regardless of ownership of the individual shafts.
Extracted reasoning
Under the drainage regulations and the cantonal agriculture law, the system must be kept functional and properly maintained. Ownership of the shafts is not decisive where free access is necessary for oversight and upkeep.
