Four New Water Treatment Plants in Selangor by 2030

Four new water treatment plants are currently under construction to meet the rising water supply demand in Selangor, reported The Star.

State infrastructure and agriculture committee chairman, Datuk Izham Hashim, said the state had planned the construction of new water treatment plant infrastructure, through Air Selangor, to ensure the water reserve margin remained above 15 per cent.

With a capacity to treat 350 million litres per day (MLD), the Rasau Water Treatment Plant Stage 1 is expected to be completed next year, he said, noting that an expanded capacity of 700 MLD was expected by 2027.

Stage 2 with a capacity of 700 MLD is expected to be completed in 2028, he added.

Phase II of the Labohan Dagang Water Treatment Plant with a capacity of 200 MLD is expected to be completed in 2029, while Phase II of Langat 2 Water Treatment Plant with a capacity of 1,130 MLD, is expected to be completed in 2030.

Izham said these in reply to Muhammad Hilman Idham (PN-Gombak Setia) during the Selangor State Assembly sitting at Bangunan Dewan Negeri Selangor in Shah Alam.

Hilman asked about the state government’s efforts to increase the water reserve margin and address the growing water demand.

Air Selangor is actively replacing pipes, upgrading assets such as pump houses and tanks, improving distribution and reticulation pipes, enhancing water treatment plants, increasing water storage capacity by building new tanks and ponds, and planning the Water Grid Interconnectivity plan.

He said Air Selangor had taken steps to reduce the Non-Revenue Water (NRW) rate in order to minimise the loss of treated water, which would help meet the increasing demand.

He added that both short- and long-term measures were being implemented to achieve this.

The long-term solution included replacing 300km of pipes per year.

Starting 2034, this plan will increase to replacing 400km of pipes per year.

“This will allow 5,000km of ageing pipes to be replaced in 15 years by 2040,” said Izham.

Another long-term solution is the formation of District Metering Zone (DMZ) to carry out water supply pressure management to reduce leakage and pipe burst incidents caused by high water pressure.

As for the short-term solution, a team of inspectors would carry out daily monitoring of water leakage at the DMZ and report for immediate action, Izham added.
