I live in an area where there is no mains drainage. Last winter we had
too much surface water for my liking.

The other day I lifted a concrete slab out of curiosity and found a
pit about a meter deep with some pipes entering and exiting it. It
turns out to be an old drainage system for my plot. Someone obviously
agreed with me about the surface water some time ago but it's been
neglected and allowed to fill up with crud.

I found the other end of the downstream pipe after a bit of digging in
a ditch adjacent to my house. It's competely clogged with soil as far
as I can get a small spade up it.

How could I unclog this drain? I thought of getting a pressure washer
and shoving it up the outflow I found in the ditch. Any other ideas
would be apprecitated.



The pressure washer sounds a very good idea. I'd go with that.

If you don't have a pressure washer, a bit of copper pipe held onto the
hose with a jubilee clip and bent over at the end to form a jet works
reasonable well. You can hack away at the blockage without fear of
knackering anything expensive. Which is nice!
