Our garden is near the base of an incline where the subsoil is clay. When
there is heavy rain, the lawn becomes sodden and often there is surface
water. Currently considering putting in perforated pipe land drains and
collecting the water in a large underground tank.

I keep thinking about renting one of those engines with a big drill bit on
them about a foot wide, and drilling a few 6 foot holes in the lawn,


But it'd be just my luck i drill into the coal mines that are below us, or
my idea would not work at all.

Have you seen this ?
