Project Description

Wastewater must be treated to remove four classes of pollutants to levels that regulators consider safe for discharge to the environment: these are nutrients, micropollutants, total suspended solids and pathogens. Utilities are granted licenses to discharge based on the performance of their wastewater treatment plants (WWTPs) and legislation-derived guidelines which consider the social, economic, and environmental impacts of wastewater discharge. The problem is that there are substantial interpretative differences between States and jurisdictions. This research established a standard risk assessment framework that provides a transparent method for assessing the relative benefits of different disposal and treatment options, and which can be applied uniformly across Australia.
