Sanitation
Compost distance to well and boundary
Germany
German neighbour law sets a setback to the BOUNDARY (≥0.5 m), not a distance to a well — there is no national well figure.
Distances and rules
A compost heap or manure pile is placed away from any drinking-water source so that organics and seepage do not reach a well or borehole, and with a setback from the boundary so odour and moisture do not disturb the neighbour.
To plot boundary
At least 0.5 m (stacking/compost setback; varies by Land)
Germany — Saxon Neighbour Law (SächsNRG), §16
To well (recommended)
Recommended: at least 8 m from a well (sanitary safety; no national figure)
Local rules
Important limitation
This is a planning aid, not a legal opinion. Before construction, check the local land-use rules, easements, the network/utility operator’s requirements and neighbour buildings.
