Is Tap Water Safe To Drink In Singapore?

Tap water might not be safe to drink in our home countries. What about in Singapore?

It is safe to drink directly from the tap, says the PUB. And rooftop water tanks are checked at least once a year, to make sure that water quality is maintained.

Singapore’s tap water is well within international guidelines set by the World Health Organisation, as well as the United States Environmental Protection Agency’s drinking water standards.

It is suitable for drinking without further filtration or boiling.

In fact, on its website, the PUB discourages households from using filtration devices such as water filters and purifiers. If such filters are not cleaned or replaced regularly, bacteria could grow on them.

At PUB’s waterworks, water from reservoirs is treated and disinfected.

“This frees the water of harmful bacteria and makes it wholesome and safe for consumption,” said the PUB.

To ensure the quality and safety of the drinking water supply, the PUB monitors water quality across the entire system: from reservoirs and waterworks, to the distribution network of pipes, all the way to consumers’ taps.

Each year, more than 400,000 water quality tests are conducted in PUB’s accredited water quality laboratory.

The PUB requires building owners, management corporations and Town Councils in charge of high-rise buildings with water tanks to engage a licensed water service plumber at least once a year to inspect the water tanks.

Where necessary, the licensed water service plumber must clean and disinfect the water tanks and certify them fit and safe for the storage of drinking water.
