Solids settle out; the liquid drains away. The whole tank is pumped out.
How to tell: Lids in the ground, a nearby soakaway, no electrics.
A powered unit that cleans the water before it discharges — only the sludge is removed.
How to tell: Runs on mains power — a control box, and a low hum or air vent.
A sealed tank with no outlet — nothing drains away, so it fills fast.
How to tell: No drainage field, and it's emptied every few weeks, not yearly.
No problem — we'll confirm the type when we're on site.
How to tell: Priced as a mid-size septic tank for now; adjusted after the job.
