PETALING JAYA: As the biggest users of treated water, domestic consumers should harvest rainwater to help maintain dam levels, said Association of Water Energy Research president S. Piarapakaran.
Based on 2012 statistics, he said 61.7% of the treated water supply in Malaysia was used by domestic consumers.
“If consumers can harvest rainwater to partially supplement their usage of treated water, it could bring about a big impact in preventing water shortages,” he said when contacted yesterday.
Piarapakaran said the people could practise rainwater harvesting according to their budget because it could be as simple as placing pails outside the house.
“At a price of RM500, consumers can also enlist a plumber to install a good rainwater harvesting system at home,” he said.
Malaysian Water Association president Syed Mohamed Adnan Alhabshi said rainwater harvesting could also help to prevent flash floods as storm water would be stored first before being gradually released into the drainage system.
“Green buildings and developments should not only focus on energy efficiency but also efficient use of water,” he added.
