Abstract: Two common problems in sanitary sewer deterioration are hydrogen sulfide attack to concrete pipe and structures and infiltration leakage into the system. Within the 100 miles (160 km) of collection system owned by a private corporation at Hawaii Kai, east of Honolulu, both problems existed. A unique, multi-faceted approach to rehabilitation of both hydrogen sulfide-damaged pipes and manholes and to infiltration has resulted in restoring the structure of the system and reducing infiltration flows to negligible amounts. Additional operational benefits have resulted from the pipe cleaning.
