Benefits, costs and enabling conditions to achieve ‘water for all’ in rural and remote Australia

Abstract

Australia will not meet Sustainable Development Goal target 6.1, to “achieve universal and equitable access to safe and affordable drinking water for all” by 2030, unless water service provision is improved to hundreds of small (less than 10,000 residents), rural and remote (SRR) communities. We have estimated the national benefits of a programme to upgrade drinking water services to ensure ‘good quality’ for 395 Australian SRR communities using a stated preference survey of 3,523 participants reflective of the Australian population. Using multiple model estimates, we calculated the willingness to pay at between AU$324 and AU$847 per Australian household per year for 10 years. Aggregating across the relevant Australian population, we calculated the aggregate willingness to pay for water quality improvements at AU$1.2–4.7 billion yr−1, or AU$8.3–33.2 billion as a 10-year net present value. We further estimated the capital and operating costs to provide ‘good-quality’ drinking water in the 395 SRR communities under three scenarios; the costs range from AU$0.51 to AU$3.29 million per community and, in total, from AU$0.2 billion to AU$1.3 billion.
