Interesting read on the alternative to a collar. Never knew that.
Believe it or not I got rid of a drain pipe in my dike years ago. My contractor skipped a collar and I had a leak around the pipe.
I have a stone lined overflow (same as emergency overflow) solely for my overflow, which feeds into a concrete opening with a pipe that is close to the surface of the ground that dumps into a highway ditch. I did have a problem with water coming out of the dike near the pipe, but it was five star moles boring about 3 feet below the surface of the dike from the emergency flow parallel to the surface all the way to the ditch. A concrete collar down below their boring took care of that.
