A ditch under the house (not mine) gets a small amount of water in it
every time it rains. I want to put a 40mm plastic drain pipe in the
ditch to drain the water. The ditch slopes slightly downhill, and into
the basement where the water collects.
I want to stop the water going past the end of the pipe, and to stop
earth getting into the pipe.
Any ideas? Perhaps I could poke the pipe through a hole in some kind
of membrane.
