Taking control of odours and corrosion in sewers

Optimal corrosion and odour management has been hindered by limited understanding of several key in-sewer processes contributing to the problems, and the lack of tools and reliable technologies to support strategic decisions and cost-effective sewer operations. A major step forward to fill the above gaps is being taken in Australia with a $20mil collaborative research project funded by the Australian Research Council (ARC) Linkage Program, 11 water industry partners and 5 university partners. The project is called the Sewer Corrosion & Odour Research (SCORe) Project.In this paper, the state-of-the-art knowledge and practice based on both published and grey literature is reviewed and key knowledge gaps and challenges to be addressed in the SCORe Project are identified. Some of the early findings from this initiative are presented.
