Singapore is an island country. Freshwater resources are extremely scarce and groundwater resources are inadequate. Despite the annual rainfall of 2350 mm, Singapore, a tropical island country, is still seriously short of water because of its land area of more than 600 square kilometers. Its per capita water resources are only 211 cubic meters, ranking second to last in the world. The daily water use of Singapore's 4 million residents depends on the collection and storage of rainwater, and the long-term purchase of water from Malaysia under the Singapore-Malaysia Water Supply Agreement. Under such circumstances, the protection and utilization of water resources has naturally become the top priority of the whole country. Therefore, Singapore has been vigorously developing desalination technology, new water and so on.

 

It is reported that the Singapore Public Utilities Bureau is currently researching the first place to use intelligent water meters, which will replace the traditional water meters used by existing user units.

 

 

In addition, users of smart water meter system can also query daily water consumption by mobile phone application or website, and receive timely notification when water consumption is high or there are signs of leakage, so as to solve the problem as soon as possible.

 

 

Singapore has an equatorial climate with an annual rainfall of about 2350 mm. Its rainfall has the characteristics of high density, short duration and small distribution area, which results in the formation of large flow in a short time and small area. Therefore, Singapore's domestic water sources are mainly collected through catchment areas and stored in reservoirs, then transported to water plants for treatment, and finally into the water supply network system. The central catchment area is a protected catchment area and also a nature reserve. Its land is specially used to collect rainwater. With the gradual increase of water demand, Singapore has used rivers to build reservoirs. The quality of raw water collected in these unprotected catchments is far inferior to that in the central catchment.

Since the 1960s, Singapore has gradually enacted environmental regulations to control industrial pollution without hindering industrial development. For example, since 1980, major air pollution sources, such as power plants and refineries, have been allowed to use liquid oil with sulfur content not exceeding 2% for power generation. This provision has been in place since 2000 and remains unchanged. Singapore also stipulates that special equipment must be installed in industries that distribute pollutants in the air to ensure that the gases emitted meet national standards. Through continuous improvement, Singapore has established a very comprehensive system of environmental laws and regulations, which can be strictly implemented. These regulations clearly stipulate that in Singapore, water is a public property, and the government intervenes in the public interest of water issues through administrative and regulatory means.
