The city has concern about tapping into existing pipe, and potential damage that may result.

There is no compromise in the structural integrity of the sewer pipe once STAR has been installed. We have specific engineering studies that are available for review. Most cities in North America will make a tap that is either 6" or 4" in diameter in the pipe for service laterals. This causes no structural damage to the sewer because the sewer pipe is merely a carrier of the waste water. It is not designed for structural strength. The strength comes from the way it is excavated, the gravel used in the bedding and the way the pipe is backfilled. If a 4" or 6" hole in the pipe doesn't cause any problems, how can a 6mm (.23") cause a problem? The robot only drills e.g. 15mm hole in a 24 mm thickness pipe.
