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?

And if that happens – so what? You just clear it again. If it happened that often, it would be a widespread problem, right?

Getting approval should not be a problem. Are you sure? As far as I know, it is usually quite different here.

Username_wahl19 Oct 2015 23:10They state here: A permit according to § 10 WHG is not required when rainwater collected from paved or built-up areas is discharged into a surface water body, provided that the rainwater is not harmful contaminated and is not discharged via a shared facility.
Of course, we will still obtain approval from the wastewater utility.

When it comes to root systems, laypeople often have little idea of how "small" root structures large trees can manage with. Shallow-rooted plants like the rowan shrub should not pose a problem anyway. Deep-rooted plants also do not extend several meters down... It is therefore advisable to familiarize yourself with the root systems of shrubs and then select appropriate plants based on the location of the pipe. The pipe will not be everywhere but will only pass through a small area along the property boundary.
