Stakeholder analysis of construction liquid waste management in Victoria, Australia

Construction sites generate liquid waste, and improper management can cause significant environmental and human impacts. Recent research in Australia revealed that multiple stakeholders with diverse interest and their lack of coordination impact the management of liquid waste. Thus, the study aimed to analyze the stakeholders in the construction liquid waste management process in Victoria, Australia, to understand the communication and coordination mechanisms present among them. The study used a questionnaire survey to identify stakeholder power, awareness, interest, support, and stakeholder networks in construction liquid waste management. Focus group was used to validate the findings from the survey. The findings show that public authorities, water corporations, local councils, building authorities, and construction companies are the key parties involved in the construction liquid waste management process. It was identified that lack of relationship between key stakeholders; lack of education, knowledge, and awareness; lack of liquid waste management requirements in building codes; and lack of strategic involvement of water corporations as four key limitations. Five strategies were identified to improve the liquid waste management process and foster the relationship among stakeholders. The findings will help as an initial step to streamline construction liquid waste management processes by clearly defining the responsibilities among key stakeholders.
