Using containers instead of hoses among ways to conserve
PETALING JAYA: Limiting showers to 15 minutes and gargling with a glass when brushing teeth are some effective ways to save water, say experts, as concerns mount that rising temperatures could lead to overconsumption of this resource.
These two methods can save a total of 95 litres per session for one individual or a combined 11,640 litres per month for a family of four, says Association of Water and Energy Research Malaysia (Awer) president S. Piarapakaran.
These simple water-saving habits can significantly reduce household consumption and bills, Piarapakaran said, adding that installing water efficient taps can further cut use by 50%.
“The mixture of water and air bubbles helps in washing soap away faster,” he said in an interview yesterday.
In the kitchen, filling a basin to wash vegetables and fruits instead of running the tap can save more than 34 litres in ten minutes, which saves a total of 1,020 litres per month, he added.
He also suggests reusing wastewater from washing clothes or cooking for watering plants or cleaning outdoor areas.
“For washing vehicles, using a pail and dipper instead of a hose can save more than 224 litres per wash.
“A small change in our habits goes a long way. We must start somewhere.”
The current southwest monsoon, which is expected to last till September, is bringing hotter days and experts say households must conserve water while staying cool.
Water and Energy Consumer Association of Malaysia president Saravanan Thambirajah said Malaysians are already using more water per capita than many neighbouring countries.
“Overconsumption can have long-term consequences on our local water resources. It threatens to deplete our rivers, dams and aquifers, especially during prolonged dry seasons.
“Communities may face more frequent service disruptions or rationing measures if consumption remains unsustainably high.”
To stay cool and conserve water, Saravanan suggested using electric or battery-powered fans as alternatives to water-based cooling methods.
“Fans are less resource-intensive. Indoors, installing reflective curtains or window films can reduce heat,” he said.
Saravanan also advocated for water-efficient appliances, particularly those certified under the Water-Efficient Labelling Products programme.
Rainwater harvesting is also crucial, allowing households to collect water for non-potable uses like watering plants, he added.
Saravanan, who is also the chief executive officer of the Federation of Malaysian Consumers Associations, said simple behaviour changes such as avoiding outdoor activities during peak heat hours can also cut water use.
Community participation is also key as reporting leaks reduces water loss and encourages civic involvement, he noted.
“Staying cool shouldn’t compromise our water security. With the right habits, Malaysians can adapt to the heat and preserve this vital resource for future generations,” he added.
