I have a 100mm pipe (4") that comes under the garage ramp and outputs the rain water to the street. My problem is that I couldn't have the pipe goes straight to the street because of the slope needed, so I diverted the pipe 45° at the sidewalk point.
The pipe end sits a bit above the curb level, so now I need to find a way to hide this pipe. I thought of maybe using a drain grate, but I couldn't find anyone with 45° corners (I could weld something, but I would be a very tedious work). Another idea is using a heat blower to compress the pipe to that it goes below the curb level, but I think this might create clogging problems.
Any other choices?
EDIT: Added a picture of the pipe in question
