The introduction of the rainwater harvesting system (SPAH) under the National Water Resources Policy and Water Sector Transformation 2040 agenda aims to support more sustainable water management, says Deputy Prime Minister Datuk Seri Fadillah Yusof (pic).
The Star newspaper quoted the Energy Transition and Water Transformation Minister said it can also reduce the demand for treated water, function as a backup during disruptions and use less energy than conventional sources.
“In line with a strategy for sustainable and resilient water resource management, the ministry, through the National Water Research Institute of Malaysia (Nahrim), has implemented several key interventions to mainstream the use of SPAH across communities, government premises and the private sector,” he said at Dewan Negara yesterday.
He was responding to Senator Datuk Rosni Sohar on the ministry’s strategic plan to utilise the potential of rainwater as a supply source during the dry season.
Fadillah cited as an example the Nahrim Tank Software 2.0, developed in 2021, which provides online simulations to determine the optimal SPAH tank size and assess its storage efficiency and potential water savings.
Additionally, he said a master plan study for a Conjunctive Water Supply System in Kuala Lumpur was also done in 2017 to identify the potential of alternative water sources in urban areas..
