I'm no drainage expert but I did use the type of pipe the man on the machine is using. Its laid into the channel (with a slight fall)and out to to an outlet (the deeper the channel the better) and then backfilled with fine stone. The pipe has thousands of tiny holes in it which allows water (sieved and cleaned somewhat by going through the stone) to percolate into the pipe and form a type of river bed within the pipe. Apparently it does take some time for the system to become effective as the water has to make its way to the pipe over time, but OMG it does work and work well. The amount of water which mine dispersed on a real wet day was literally like turning a tap on. But there needs to be a adequate outlet! SBL
