Case Studies

The existing sewer to be rehabilitated was approximately 80 years old and was located 20 ft. below ground in Evanston, Illinois, a northern suburb of Chicago. The sewer started at a river edge overflow chamber in a school parking lot.

The galvanized corrugated vertical inflow stand pipe on the golf course 6 acre pond was deteriorated badly.  The holes in the pipe were significant and caused the pond level to be over 3 feet below normal pond elevation.
