Underground drainage

[willwillscrisp]

Hello, I've had to go back on myself with the underground drainage, does anyone know if this is ok? Water flows fine, it's 1:40 fall, but not sure if it's with regulations?

Not an issue

Think a bottle gulley would have worked better, from the being able to rod it point of view

Ask your BCO ?

Its ok, the junction is roddable. I'd have had it on the adjacent (downstream) run.

Thanks, I did try but need the gully in the corner to near to the chamber to get the trap done!
