Integrated odour management

Offensive odours from wastewater networks can have a serious impact on ratepayers and cause a vexing problem for Network Owners and Operators to resolve. This paper outlines an integrated approach to dealing with wastewater odour issues from existing systems, using the Hibiscus Coast Trunk Wastewater System experiences as an example.

Technical methodologies are outlined as a tool to integrated odour management, along with process methodology and fundamental philosophies to integrated odour management. Airflow auditing, network operational strategy, construction detailing and venting requirements are also considered. The paper includes the importance of reliable asset information and thorough communication strategies with affected parties. The value of community interaction and engagement in parallel to the technical competencies is demonstrated. Innovative methods for point source odour control are also outlined, together with system operational philosophies and analytical methodology.
