Water Sustainability<br />

While reams of newsprint have been devoted already to the Mumbai, India authorities’ efforts to clean up the Mithi<br />

River, the highly developed city-state of Singapore is putting together a high-level plan to market its waste-water<br />

technology globally. Singapore’s Ministry of Environment and Water Resources (MEWR) has recently set up the<br />

Environment and Water Industry Development Council (EWI) to spearhead the growth of the environmental and water<br />

industry in Singapore. The government plans to develop Singapore as a global hub for environment and water for<br />

business, investment, research and technology.<br />

SINGAPORE targets to grow value-added contribution from the water sector from $0.5<br />

billion (0.3% of GDP) in 2003 to $1.7 billion (0.6% of GDP) by 2015. Jobs for this sector are<br />

expected to double to about 11,000 in 2015 with a large part of the growth in professional and<br />

skilled categories. According to the MEWR’s website EWI, the on-going efforts of other<br />

governmental agencies such as EDB; IE Singapore; the Agency for Science, Technology &<br />

Research; National Environment Agency (NEA); Nanyang Technological University (NTU);<br />

and National University of Singapore (NUS) will:<br />

• Attract more companies to locate their operations in Singapore<br />

• Help local companies to grow<br />

• Encourage more companies and research institutes to develop cutting-edge water<br />

technology and<br />

• Further export Singapore’s capabilities to growing markets, especially in the Middle East<br />

and China<br />

Potential for Growth<br />

With the growing global emphasis on water and the environment, Singapore is well<br />

placed to take the lead in this industry as an R&D base, and also as a provider of water<br />

solutions. To meet the country’s water challenges, Singapore has been investing heavily<br />

in water-related research and technology for the last four decades, and it has developed<br />

excellent capabilities in the field of water management. With the development of major<br />

national water projects such as NEWater, the Deep Tunnel Sewerage System and Marina<br />

Barrage, Singapore has turned its vulnerability in terms of water into a strength; this has<br />

resulted in a thriving water industry eco-system with more than 50 international and<br />

local companies in existence.<br />

Clean Land<br />

In Singapore, the waste disposed goes into incineration plants or into landfills. If the<br />

current volume of waste keeps increasing, Singapore will need to build large incineration<br />

plants and find new places for landfills. In land-scarce Singapore, where land is required<br />

for schools, houses and other uses, this is not a sustainable option. To address this issue,<br />

the strategies of volume-reduction by incineration, waste recycling, reducing land-filled<br />

waste, and waste minimisation have been identified. Currently, about 90% of the waste<br />

is incinerated, while the remaining non-incinerable waste is land-filled. However, the<br />

demand for land-fill is still too high. Hence, there is a need for recycling efforts (like the<br />

National Recycling Programme introduced in 2001), and a need for trying to find useful<br />

applications for incineration ash. It is also important for consumers and producers to<br />

minimise the amount of waste generated.<br />

Solid Waste Management<br />

With limited resources available for waste disposal, the National Environment Agency’s<br />

(NEA) policy for waste management necessitates the incineration of all incinerable waste<br />

that is not recovered, reused or recycled. Non-incinerable waste such as concrete slabs, bulky<br />

waste materials and incineration ashes are disposed of at the offshore Semakau Land-fill.<br />

Core Strategies for Sustainability<br />

• Minimise waste through reducing, reusing and recycling to ensure long term sustainability<br />

• Towards zero landfill<br />

• Develop the recycling industry and position Singapore as a centre for recycling technology<br />

in the region<br />

Clean Water<br />

Water is a scarce and precious resource because as a small island city-state with<br />

an increasing demand for water, Singapore has to make every drop count.<br />

Rainwater that falls within the catchments areas is collected in reservoirs. Today,<br />

about half the area of Singapore is being utilised as catchments for rainwater<br />

collection. With plans to build more reservoirs, drains and canals, the local<br />

catchments will be expanded to about two-thirds of the island. Even as we increase<br />

sources, it is also important to keep water demand low.<br />

Core Strategies for Water Sustainability<br />

• Enhance robustness and resilience of water supply sources<br />

• Develop effective water-demand management strategies<br />

• Build up a vibrant water industry<br />

• Encourage greater private sector participation<br />

• Study and explore alternative policies, technologies and strategies to ensure<br />

long-term sustainability of Singapore’s water supply<br />

Public Health<br />

Singapore’s public health record is enviable. The country is respected<br />

internationally for its high standard of public health. It is one of only two<br />

Southeast Asian countries recognised by the World Health Organisation as<br />

having eradicated malaria (the other country is Brunei Darussalam). Cases<br />

of serious food-related illnesses, such as cholera and typhoid fever, which<br />

usually result from poor sanitation and low food hygiene standards, have<br />

been kept at a minimum. In 2003, there was only one local case of cholera<br />

and three cases of typhoid. This is no mean feat as Singapore is an ‘open<br />

city’, situated in a region that is endemic for various tropical diseases such as<br />

dengue fever and malaria.<br />

With so many people, ships, vehicles and aircraft coming and going across<br />

Singapore’s borders each day, and with the increasing numbers of new and<br />

mutated viruses in circulation, the country maintains its vigilance to prevent<br />

major outbreaks of known and potential diseases. Its high health standard has<br />

been achieved with the co-operation of the wider community and the country’s<br />

private sector.<br />
