As much of the nation’s wastewater and sewer infrastructure approaches the 50-100 year mark, it must be rehabilitated to remain in use for a growing population. Yet municipal wastewater treatment facilities, sewers and vaults endure some of the most severe and corrosive environments in the water industry and must pass increasing Environmental Protection Agency (EPA) scrutiny. At industrial plants as well, EPA enforces requirements to ensure that industries pre-treat pollutants in their wastes to protect local sanitary sewers and wastewater treatment plants.
Such extreme wastewater handling environments operate under continual chemical exposure and heavy abrasion that deteriorate concrete and corrode steel in clarifiers, containment pits, anaerobic digesters, manholes, tanks, and other infrastructure assets.
A variety of factors can cause these structures to develop sizable cracks through which wastewater can escape (exfiltration) or groundwater can enter the wastewater system (infiltration). Leaks, cracks and damage to existing coating systems not only top the list of challenges in facility maintenance and new constructi
