Hints and tips: When building with round sewer in a cobblestoned (part #180) street, come as close as possible with regular size stones, then cut stones with plastic snips to fit odd area. Fill in with putty between stone and wipe away excess.

If you want to show an open sewer, cut a round hole with hole-saw no larger than sewer ring through BASE #1001. Arrange bricks #120 in circle under and around sewer opening. Sewer height is about even with top surface of cobblestones.
