PETALING JAYA: It will take at least four days for water supply to be restored, once the four water treatment plants that were shutdown on Thursday (Sept 3) due to odour pollution, resume operation, says Air Selangor chief executive officer Suhaimi Kamaralzaman.
He said the water treatment plants have been shut for over 30 hours and it would take a long period to restore water supply.
“Sungai Selangor’s Rantau Panjang, Phase 1, Phase 2 and Phase 3 water treatment plants were shut after odour pollution of three TON (threshold odour number) on Thursday was detected. As of 2.30pm Friday (Sept 4), the odour pollution is at one TON.
“Water treatment plants will only begin operation once the odour pollution hits zero TON, at three consecutive readings, which are being taken every 30 minutes,” he said.
In comparison, Suhaimi cited two water disruptions, which happened back-to-back in July, due to pollution which caused the shutdown of the same four water treatment plants.
“The first incident on July 19 caused the water treatment plants to be shut down for five hours. It took 72 hours for the water supply to begin restoration.
“The plants were shut down again on July 21 due to another contamination and were shut down for another five hours.
“Cumulatively, there was a 10-hour closure of the four water treatment plants. And the consumers who lived the farthest away from the plant did not have water supply for seven consecutive days,” he said.
