Natural resources, environment and climate change minister Nik Nazmi Nik Ahmad said the existing water tariffs, including for domestic accounts, would be reviewed when the mechanism is used in future.

A review of tariffs is necessary to overcome non-revenue water problems and improve water infrastructure, Bernama reported him as saying when launching the sustainability achieved via energy efficiency 4.0 (SAVE 4.0) programme at the ministry’s booth at the Bukit Jalil National Stadium here today.

On SAVE 4.0, Nik Nazmi said the public could obtain rebates of up to RM400 to purchase energy-efficient air conditioners and refrigerators with four-star or five-star labels issued by the Energy Commission starting from today.

He added that RM50 million had been allocated to implement the programme and it would continue until all the funds are utilised.

Domestic electricity account owners can enjoy the SAVE 4.0 rebate, which is limited to one account for every purchase of an air conditioner or a refrigerator.

They need to bring an updated electricity bill when making a physical purchase at any electrical shop or shopping mall registered with the programme or apply for an e-rebate for online purchases on accredited e-commerce platforms.
