Corrosion and odor of sewers is an increasing concern because of tighter controls of the industrial waste (heavy metals), drinking water conservation programs, and the growing trend towards more centralized larger wastewater treatment facilities. This makes the sewage typically more septic, resulting in hundreds of millions of dollars in damage to sewers including collapse of sewers in densely populated areas. Many of the odor and corrosion issues are dealt with in a reactive manner, often providing temporary or expensive solutions. Addressing corrosion and odor problems in sewers is challenging, in part because historically there has not been reliable calculation methods and computing capability of predicting corrosion and odor formation rates because of the complexities in doing so. Can sewer process assessment tools such as sewer process modeling address the above challenges opening the way for a more pro-active approach, so that reactive trial-and-error approaches can be avoided, asset management risks can be better quantified, and cost can be saved of field inspection campaigns? This webcast will provide a comprehensive understanding of sewer processes, will illustrate the latest developments, including an appreciation of the advantages (and limitations), of sewer process assessment tools, and will illuminate the role of a sewer as reactor (with physical, chemical, and biological processes), rather than simply a system for conveyance (hydraulics) of wastewater.
