I have a downpipe at the front of my bungalow. It currently runs along a garden wall and out onto the street. All the other bungalows have the same accept their downpipe just sits outside their house without any drain. I want to remove the wall to enable parking. What do I do with the downpipe? My font garden is block paved and has a slight slope back to the property. I can post a picture if that helps?
