Sanitation
Septic tank distance to house, well and boundary
États-Unis
No national norm: the tank keeps ≥15 m (50 ft) to a well (state health rules); the drainfield often 30 m (100 ft). Distance to house and boundary is local zoning.
Distances et règles
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.
To well / drinking water
At least 15 m (50 ft) to the tank; drainfield often 30 m (100 ft)
