    Abstract In addition to mounting water demand, Bali’s water supply has been constrained by high levels of water pollution. Efforts to control water pollution have not been effective, mainly owing to their reliance on traditional methods and regulations focusing on water pollution being linked to discrete sets of economic activity. However, an economy of a region/country comprises a set of sectoral activities, which are interconnected through supply chains; thus, water pollution could be well explained by examining the entire sectoral economic activities and their environmental performance. Determining the structural relationships between water pollution and economic activity serves as an important basis for more effective forms of pollution control for the Balinese economy. In this study, we employed an environmentally extended input–output model to establish the links between water pollution and the production processes of the entire economy. Using biochemical oxygen demand (BOD) as a proxy for water quality in our analysis, we estimated that 246.9 kt of BOD were produced from Bali’s economic activity in 2007. Further, we identified the chief BOD-emitting sectors and found that intermediate demand and household demand were the major causes of BOD discharge in the economy. We also accounted for the indirect role of each sector in total BOD emissions and categorized the sectors into four groups based on their direct and indirect BOD emission characteristics and offered appropriate policy measures for each group.
