More than 200 companies and organisations that took part in PUB’s “10 per cent Challenge” have successfully managed to reduce their water usage by 10 per cent in the last four years, the national water agency said.
February was Singapore’s driest month in 145 years since records were kept and statistics show that the Republic uses about 400 million gallons of water per day.
Last year, 45 per cent of water usage was attributed to households, with commercial operators and government buildings taking up the rest.
By 2060, commercial usage is expected to form 70 per cent of Singapore’s water consumption.
PUB said 342 organisations have developed and submitted their Water Efficiency Management Plan as of last December, and 204 of them have managed to shrink their water usage by 10 per cent.
One of the companies that has successfully cut down its water usage is City Developments Limited.
It uses waste water and rainwater to test water-proofing in newly-built toilets and to wash the tyres of heavy vehicles to prevent them from soiling public roads.
At construction sites, it uses an underground water storage tank to collect rain water, which is then used for other purposes, for example, to water plants when the project is completed.
Recycling water helps the company save S$280.
Chew Chin Boon, a project manager with City Developments Limited, said: “When the project is completed, the rainwater tank will remain. It will be used to collect rainwater and the condensate from all the units’ aircons. The water will be used to water all the plants in the estate.”
