When it rains, we get a lot of water running off the land behind us (semi wild). This then accumulates into large puddles on the grass. I was going to put down some of those large drainage pipes (water soaks into them and runs through the pipes), but wondered if I could make a bit of a feature of things and and create a stream where the water comes into the garden and channel this into piles that will go under the rest of the garden (grass). I've seen pictures of dry streams (lined with stones that channel water when it rains.
has anyone done this? Are there any flaws to my plans? (Probably!!)
