Sewer cost on infill housing will become less and less of an issue as the older combined sewers in the city are twinned with new land drainage sewers. This is only beginning to happen. Right now in St. James and Grant Park areas. The flow in the sewers that were combined and are now wastewater only is substantially reduced.

Water line renewals are constantly happening also, with upsizing. So costs on infill are minimal unless it is an entire brownfield development. But, an exception might be old industrial lands since they require large diameter fire lines already.

So I think it is a case-by-case situation. Especially since you really can't plug numbers on sewer and water installation. There is no table values based on pipe size or depth that can be reliable because ground conditions vary significantly throughout the city.
