Septic tank distance to house, well and boundary — Türkiye

Türkiye

National minimum: ≥2 m from house walls, ≥1.5 m from a well; the boundary distance is set by the local zoning plan.

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.

To house walls At least 2 m Local rules

To well / drinking water At least 1.5 m (national min); basin zones require more Local rules

To plot boundary (recommended) Recommended: at least 3 m (covers the local zoning plan with margin) Local rules
