Singapore's drinking water system is a global benchmark for safety, innovation, and sustainability. According to Yale University's 2024 Environmental Performance Index (EPI), Singapore ranks No.1 worldwide in providing safe and clean drinking water - scoring 99.9 out of 100.
This remarkable achievement highlights not only its advanced water treatment technology but also the nation's deep commitment to public health. Yet, interestingly, many Singaporeans still prefer filtered or boiled water at home, reflecting their exceptionally high standards and strong sense of precaution.
Singapore's National Water Agency, PUB, is recognized for its automation and precision in monitoring water quality. PUB continuously tests for chemical, microbial, and radioactive contaminants through a real-time surveillance network.
Their system integrates water recycling and desalination into a sustainable cycle, ensuring every drop - from tap to tank - meets or exceeds WHO and US EPA standards.
Singapore's innovation doesn't stop at filtration. Since 2012, PUB has used Fish Activity Monitoring Systems (FAMS) - live fish that act as natural water quality sensors. When the fish display unusual movements or mortality, the system automatically alerts operators to potential contamination.
Alongside this, robotic "water-monitoring swans" patrol reservoirs. These smart devices, disguised as real swans, are equipped with propellers, pH sensors, cameras, and sample collectors. They can even access difficult-to-reach areas, collecting live data for chemical analysis.
| Monitoring Technology | Function | Purpose |
|---|---|---|
| Fish Activity Monitoring System (FAMS) | Observes fish behavior | Detects early signs of contamination |
| Robotic Swans | Automated patrol and water testing | Monitors pH, chemical balance, and pollutants |
| Online Analyzer Network | Continuous monitoring in pipelines | Tracks physical, chemical, and microbial parameters |
PUB's laboratories conduct over 500,000 water tests every year, covering more than 300 parameters - more than double the international minimum standard of 130.
Water samples are taken from 124 fixed sampling points and additional random household taps daily. Automated lab systems introduced in 2017 help increase productivity and reduce human error, ensuring every test is both fast and precise.
PUB also operates mobile laboratories that respond within 1–2 hours during emergencies, enabling instant, on-site testing.
Singapore's water pipes are built to last. Since 1986, PUB has used ductile iron pipes with superior strength and corrosion resistance. Starting in 2010, all pipes have been coated with polyurethane for extra durability.
CCTV inspection robots are deployed to assess pipelines internally before approval, and old pipes (especially those over 50 years old) are regularly replaced.
Building owners are also legally required to maintain their rooftop water tanks annually, using only PUB-certified plumbers. Failure to comply can result in fines or suspension of licenses.
Singapore's commitment to clean water sets the standard for global home water technology. As consumers become more aware of water safety, under-sink drinking water systems and 4 in 1 hot water taps are increasingly popular in modern kitchens.
These systems - which provide filtered, chilled, boiling, and ambient water instantly - allow households to enjoy Singapore-level water safety anywhere in the world.
