To inform the public.
Description:
This information is relevant to the development of condition assessment tools associated with the aging water infrastructure research program Corrosion of wastewater collection infrastructure, especially concrete sewers, is a significant cause of deterioration and premature failure. When exposed to the internal atmosphere of gravity sewers which is characterized by high humidity and the presence of hydrogen sulfide, sulfuric acid corrosion negatively affects concrete surfaces, mortar, and metal reinforcement material. Given this universal challenge for wastewater utilities, this research project will look into an innovative condition assessment method development that addresses corrosion-related wastewater infrastructure issues.
