What exactly is a leech field?

Question

I know it has something to do with a septic system but I'm unclear...

Answer 1

Actually it's "leach" field.  Basically it's a network of perforated pipes buried in the soil that allows the water inside to seep into the soil over a large area rather than dumping it all out in a single spot.

Answer 2

The term is leach field, or widely termed a septic weeping bed.

Tiles laid out at  a depth that may almost prevent freezing will weep sewage water into the gravel below the tiles, from which it will leach or drain into surrounding soil, even return to the aquifer.

Leech by contrast is a blood sucking critter that lives in streams and ponds, sometimes used to remove excess blood, as from a bruised area.

Answer 3

Septic drain fields are used to remove contaminants and impurities from the liquid that emerges from the septic tank. This is typically done by burying perforated pipes in trenches and allowing the liquid to leach out and the surrounding soil absorbs the unwanted waste. Another term for this is a leach field.
