From tackling a water supply crisis to meeting our current demand of 430 million gallons of water a day (about 782 Olympic-sized pools), Singapore has come a long way in achieving water security.
With robust diversified water sources and potable tap water, the younger generation might find it hard to imagine the water shortages of the 1960s and water rationing in the 1980s. By 2060, however, Singapore's total water demand could almost double, and the production of water is also an energy-consuming process.
Maintaining sustainable water consumption is still a priority, and everyone needs to play a part. Besides the usual water-saving methods such as using a half-flush in the bathroom and running the washing machine on full loads, here are some creative ways to save water.
Contain the Flow
Your water bill shows how your water usage compares to other households of the same size. In Singapore, those who use more than 40 cubic metres of water a month – about 250 bathtubs – are charged more per cubic metre.
In 2021, each person used about 158 litres of water at home per day, up from 141 litres in 2019. This is likely due to the COVID-19 pandemic as people spent more time working or learning from home, and did more frequent handwashing, showering and cleaning.
Even as Singapore continues to grapple with COVID-19, it is important to ensure that everyone uses water wisely and plays his or her part for a sustainable future.
To reduce your household water usage, purchase more water-efficient appliances and use the free water-saving kit from national water agency PUB. It comprises four thimbles for taps and two thimbles for showerheads, allowing you to regulate flow rates.
It’s also wise to turn off the tap and use a container when brushing your teeth, rinsing vegetables and hand-washing reusable face-masks.
