BACKGROUND:
The Department of Public Works (DPW) maintains the City's system of storm sewers. Storm sewers have a functional lifespan of approximately 75 years. As a storm sewer ages, the pipes develop cracks caused by material degradation, soil settlement, root intrusion, and/or adjacent construction.
