Water Reuse Practice and Projects:An Overseas Perspective

摘要

Planned and deliberate DWR is not a new concept and has been used around the world since the late 1960s. Countries such as Namibia and Singapore have successfully leveraged new treatment technologies and public acceptance programs to produce a stunning array of recycled water projects and systems that now underpin key commercial and industrial sectors. Nearly every visitor to Singapore has benefited from the NEWater program. Water recycling projects continue to expand and grow more needed in dry and parched states such as Texas in the US and the deserts of Saudi Arabia. Now Asian powerhouses of China and India are investing and planning major projects to recycle 100% of their wastewater, or are deliberately planning drinking water reuse projects to overcome chronic shortfalls in water supply. All of these countries know of the economic benefits and importance of using water more than once. As they continue down their path of rapid urbanisation and development, the need to recycle or reuse water will become an essential infrastructure platform rather than a luxury.
