PETALING JAYA: The water supply to Bandar Baru Bangi and the areas in its vicinity are not affected although two treatment plants were shut down due to the odour pollution that was detected in Sungai Semenyih.
Environment and Water Ministry secretary general Datuk Seri Zaini Ujang said consumers in the area received their water supply from Phase II of the Semenyih treatment plant.
"The phase II plant gets its raw water supply from a riverside reservoir originating from Sungai Langat, ” he said.
Zaini added that the Semenyih Water Treatment Plant is divided into two phases.
“The Phase I plant with 650 million litres per day capacity sources raw water from Sungai Semenyih while the Phase II plant with a 100 million litres per day capacity sources raw water supply from a riverside reservoir (TAPS) originating from Sungai Langat," he said
Zaini added in a Facebook post on Monday (Oct 5) that the shutdown of the Semenyih Treatment Plant only involves Phase I.
"Operations at Phase II of the plant continues, supplying water to Bandar Baru Bangi and its vicinity. Plans to build TAPS for Phase I have been in the pipeline since 2017," he said.
He also said that Putrajaya had a large reservoir of 110 million litres of treated water.
"The supply (in Putrajaya) could last several hours, depending on the rate of usage," said Zaini.
