Economic sustainability is an integral aspect of sustainability, meaning that humans utilise, protect and conserve human- and material-based services in order to create renewable long-term assets by an optimal utilisation, recycle and recovery. Building investments and running costs are fiscal metrics utilised in economic sustainability indices. Capital costs are accumulated expenditures when the process starts. Capital expenditures rely largely on the type and process of treating waste water. Usually, these costs involve planning, construction, equipment and facilities, electrification, induction, training, start-up, substitute components, cost of reservations, etc. This paper explores some of the instruments for calculating economic sustainability. That include exposure analysis (SA), particulate matter analysis (PCA) and cost-benefit analysis (CBA).
