Hello, we would like to drain the rainwater into a stream at the property boundary. With the garage and terrace roof, the total roof area to be drained is about 150 sqm (1,615 sq ft). Obtaining permission should not be a problem. I am wondering what the best way to implement this would be. The distance across the garden is about 35 m (115 ft).
Underground PVC pipes would probably limit us with garden planting because of the roots, right?
A surface channel would therefore appeal to me more, but what is the best material to use so that it also looks good?

They write here:Wow, the link explicitly states that a) it is allowed and b) no specific permit or planning permission is required. Great!How about an artificial stream with a natural stone bed?

However, to actually enjoy the stream in action while sitting in the garden, you would need to order a local rain shower for the roof every time. Sitting outside in the rain watching the stream somehow doesn’t really seem enjoyable.
