How it's done
The spot is chosen relative to the building, the well and the neighbor's boundary — there are minimum distances you can't fix later. We dig with working room around the tank. After installation the backfill goes in layers, so the ground doesn't sink after the first rain.
When we say no
With a high water table, a three-meter dig without shoring is dangerous. Then we either dig in stages or suggest a shallower solution.
What to know afterward
Don't park or build over the pit, and keep the lid accessible for pumping.
Also known as
cesspit, septic tank, holding tank, watertight tank, sewage treatment plant, tank excavation
