Wastewater management in the construction sector: A systemic analysis of current practice in Victoria, Australia

Construction activities can use large amounts of water resulting in the discharge of contaminated wastewater from construction sites. However, research into wastewater management in the construction sector is scarce. The objective of this exploratory study was to understand the regulatory and practical aspects of wastewater management in the construction sector in Victoria, Australia. Exploratory interviews among 15 participants from regulatory authorities, local councils and construction firms were conducted. The interviews showed that there was a disconnect between the construction and water authorities and a lack of understanding of wastewater related regulations among construction practitioners. The findings of the interviews were used to develop a system map to illustrate how the system operates and to identify possible intervention points to optimise the system. The evidence from this study suggests that a more collaborative approach across the different agencies is vital to streamline wastewater management practices in the construction sector and the regulatory framework.
