Koonung Creek Septicity Assessment Using the ASCENT Model
Abstract
Almost all sewerage systems of a substantial size face the potential for sewage to turn septic (anaerobic). Under these conditions “sewer gases” can form in the headspaces of the sewerage system, which can lead to corrosion of sewerage structures and the release of odours into the environment.Yarra Valley Water (YVW) faced such a situation in a number of its catchments. In 2011, YVW requested that MWH utilise the MWH ASCENT (Airflow, Septicity, Corrosion, Engineering Network Tool) Model on one catchment to assist in determining the Model's usefulness. After an analysis of various available catchments, MWH selected the Koonung Creek catchment as the most appropriate for this study.
