Question
Richard,

    The output of our washing machine is out on a hill that slopes off into grass.  We just replaced the entire line from its connection (corrugated plastic pipe), and there is no other place to put it.  We have tried putting rocks right where it comes out, but the force when it drains is pretty strong.

    What alternatives would you suggest to keep the hill and down lower washing out?

                      Thanks, Alan


Answer
put a plastic(like a pond liner) under the rocks(rocks should be round boulder type river rocks 3-6"). extend the run as far out as it takes to slow the water sufficiently. you could make a dry well by making a hole 3-4' deep by 2-3' across under where the river stone is. line the bottom, sides, and top w/a geotextile(mirafi, etc.) before placing stones in the cylinder shaped hole. add more rock over the last layer of mirafi.
good luck
