Water: From Scarce Resource to National Asset Water: From Scarce Resource to National Asset recounts Singapore’s remarkable water story. Although surrounded by STUDIES URBAN SYSTEMS water, Singapore is one of the world’s most water-stressed countries. Singapore’s water system involves a delicate balancing act on two fronts. Firstly, the country seeks to maintain its imported water supply from Malaysia, while ceaselessly exploring alternative sources through technology and public mobilisation. Secondly, it has to balance land requirements for water catchments with competing needs for housing and industry. Demand is also calibrated to the thimbleful. As an expensive commodity, water is priced to reflect not just the high cost of storage, processing and distribution, but also its strategic value. Public education and Asset From Scarce Resource to National Water: community engagement were also used to manage demand. This study also examines how Singapore achieved a paradigm Water: From shift in its water management by using new technologies, such as membranes and desalination, new drainage and Scarce Resource flood control systems, as well as innovations such as building reservoirs in urban areas. to National Asset “Every other policy has to bend at the knees for our water survival.” Lee Kuan Yew, first Prime Minister of Singapore. 9 789811 447921 Water: From Scarce Resource to National Asset Urban Systems Studies Books Water: From Scarce Resource to National Asset Transport: Overcoming Constraints, Sustaining Mobility Industrial Infrastructure: Growing in Tandem with the Economy Sustainable Environment: Balancing Growth with the Environment Housing: Turning Squatters into Stakeholders Biodiversity: Nature Conservation in the Greening of Singapore Financing a City: Developing Foundations for Sustainable Growth Land Acquisition and Resettlement: Securing Resources for Development Built by Singapore: From Slums to a Sustainable Built Environment Planning for Tourism: Creating a Vibrant Singapore Cleaning a Nation: Cultivating a Healthy Living Environment Urban Redevelopment: From Urban Squalor to Global City Port and the City: Balancing Growth and Liveability The Active, Beautiful, Clean Waters Programme: Water as an Environmental Asset Working with Markets: Harnessing Market Forces and Private Sector for Development A City of Culture: Planning for the Arts Sino-Singapore Guangzhou Knowledge City: A New Paradigm in Collaboration Land Framework of Singapore: Building a Sound Land Administration and Management System Water: From Integrating Land Use & Mobility: Supporting Sustainable Growth Engaging Well, Forging Bonds: The Community as Stakeholders in Urban Development Food and The City: Overcoming Challenges for Food Security Scarce Resource to Technology and the City: Foundation for a Smart Nation Energising Singapore: Balancing Liveability and Growth National Asset one-north: Fostering Research, Innovation and Entrepreneurship Planning for a Secure City The Rule of Law and Urban Development Past, Present and Future: Conserving the Nation’s Built Heritage Integrating the Planning of Airports and the City: The Singapore Story Resettling Communities: Creating Space for Nation-Building For product URBAN SYSTEMS CLC PUBLICATIONS information, STUDIES SERIES https://www.clc.gov.sg/research- visit www.clc.gov.sg/research- publications/publications/books publications/publications/ Second Edition, Singapore, 2020 urban-systems-studies Water: From Scarce Resource iv v to National Asset Editorial Team Writers: Yang Wen, Kuang Jin Yi CONTENTS Research Supervisors: Neo Boon Siong, Limin Hee Editor and Production Manager: Gregory Lee Foreword vii Preface ix Designer: Redbean De Pte Ltd Acknowledgements xi The Singapore Liveability Framework xii Overview The Journey From Scarcity to Sustainability 1 © 2020 the Centre for Liveable Cities Chapter 1 The Early Days of Water Management 3 First edition © 2012 Cengage Learning Asia Pte Ltd All image rights are owned by the Centre except where indicated otherwise Chapter 2 Water Supply—Towards Water Sustainability 11 • The Four National Taps 12 CLC is a division of – The First National Tap—Domestic Sources 12 Cleaning the Singapore River—Providing Alternatives, 16 Set up in 2008 by the Ministry of National Development and the Ministry of the Environment Managing Trade-offs and Water Resources, the Centre for Liveable Cities has as its mission “to distil, create and - The Second National Tap—Imported Water 20 share knowledge on liveable and sustainable cities”.

Timeline 64 Endnotes 72 Despite an abundant average rainfall of 2,200 mm/year, there were Bibliography 75 insufficient catchment areas to capture and store the rainwater in the Appendices 78 1970s. The water shortage was exacerbated by the polluted waterways that rendered rainwater flowing in them unfit for treatment for drinking purposes. The open sewers, poor sanitation and seasonal floods further compounded the pollution problem. The Water Urban Systems Study succinctly captures how Singapore was able to turn its water constraints into a virtue, highlighting the three key principles that underpinned the efforts of PUB, Singapore’s National Water Agency, in ensuring water sustainability—Collect every drop of rainwater, Collect every drop of used water, and Reuse every drop of water more than once. These principles have successfully been translated into results through the government’s financial prudence, foresight to plan ahead, commitment to meticulous implementation, and strong support from the people, public and private sectors. Water: From Scarce Resource viii ix to National Asset These would be the same principles that we would draw upon to face the PREFACE challenges that Climate Change would bring to our water supply system.
