Septic tank distance to house, well and boundary
Spain
To house ~5 m, to well ~30 m, to boundary ~5 m.
Distances and rules
A septic tank is placed at a distance from the house — so it does not undermine the foundation and odour does not reach the windows — and well away from any drinking-water source, since leaks can contaminate a well or borehole. A setback from the boundary is also kept so the tank stays accessible for servicing and pumping.
