Abstract
Quantification of greenhouse gas emissions for decentralised water supply systems is essential for water policy development, decision making and implementation of these systems. Two potential water supply strategies ‘Effluent Reuse’ and ‘Stormwater Harvesting’ applicable for the planned growth centre development of Western Sydney were developed. The associated energy intensities and operational greenhouse gas emissions of these two strategies were quantified by using the factors and methods prescribed by the Department of Climate Change and Energy Efficiency National Greenhouse Accounts Factors, 2011. It was found that in terms of operational greenhouse gas emissions, stormwater harvesting performs marginally better than effluent reuse while the cost of stormwater harvesting is expected to be about four times cheaper than effluent reuse in Australia.
