SHAH ALAM: Indah Water Konsortium (IWK) Sdn Bhd says it informed the National Water Services Commission (SPAN), Selangor Environment Department and the Selayang Municipal Council about white foam and red water flowing into its Taman Velox, Rawang plant over a week ago.
IWK said that its workers had detected the entry of illegal wastewater into the sewage treatment plant on Nov 4 and made a report on the same day.
IWK also immediately stopped the discharge of effluent at the plant to avoid any pollution to water bodies, it said in a statement Thursday (Nov 12).
It added that on Nov 5, SPAN and IWK’s investigations found two premises near the plant that were suspected of releasing white liquid used in the manufacture of cosmetics and red liquid believed to be from printing coloured paper used for prayers.
“The two elements detected resembled the illegal wastewater discharged into IWK’s plant in Taman Velox.
“Based on the findings, IWK lodged a police report at the Rawang police station and Gombak district police headquarters for further investigation,” it said.
IWK added that it had taken immediate action upon detecting the pollution, including treatment using hydrogen peroxide to improve the biological treatment process, defoamer to remove contaminants, removal of contaminated wastewater into storage tanks and 24-hour monitoring at the plant.
Additionally, on Nov 10, green-coloured illegal wastewater was detected in the Taman Velox plant and IWK immediately transferred it to another IWK sewage treatment plant for off-site treatment.
“IWK remains committed and shares information with the authorities in tackling the issue of the entry of illegal wastewater into sewage treatment plant and hopes that all parties also help to identify the perpetrators of environmental crimes that pollute our water resources,” it added.
Selangor Tourism, Environment and Green Technology and Orang Asli Affairs Committee chairman Hee Loy Sian had claimed that IWK had failed to communicate news of the effluence to authorities in a timely manner.
“It is a critical factor to communicate the information ... as not all authorities are in one central location. If the information had come in on Nov 4 via WhatsApp, it could have been addressed,” he said at his office at the Selangor State Secretariat Building in Shah Alam on Thursday.
SPAN in a statement Thursday had also denied that it was slow to address the water pollution issue as alleged by Hee on Nov 11 at the Selangor State Assembly sitting.
