A septic tank treats only 60–70% — soil finishing (drain field/soakaway) is required. On high water table or clay it won't work — a bio-treatment plant is needed.
Required distances: ≥30 m from a well on sand (≥50 m on rock), ≥5 m from the house, ≥1 m from the boundary. A bottomless cesspit is prohibited — sealed only.
