The Public Works Department (JKR) said that unpredictable weather is causing the discolouration in the water supply.
“Prolonged rainy weather at the river raw water catchment area has caused changes in the state of raw water,” the JKR said in a statement.
The statement continued, “It causes an increase in mineral and organic matter content, which in turn contributes to high levels of discolouration.
“The work of processing the water is difficult, and also results in a reduction of clean water. Therefore, some areas are currently experiencing a disruption in the water supply and low water pressure, especially for high rise areas, as well as poor water quality.”
To address this issue, the department is implementing several operational works such as cleaning water storage tanks; using additional chemicals; and ensuring the proper functioning of filtration tanks, cleaning pools, chemical doses, pumps and so on at the Water Treatment Plant; and monitoring the quality of raw water.
In addition, the department constantly monitors the quality of water supply based on the guidelines of the World Health Organization (WHO) Standards, while also conducting regular routine monitoring of water sample testing and continuous flushing operations of water pipe networks in the affected areas.
Members of the public, especially those with house water tanks and private water filters, are urged to make sure that the equipment are in clean condition by performing routine flushing and backwashing.
The public is also advised to boil water before drinking and cooking, and to exercise frugality in water consumption.
