KUALA LUMPUR: Indah Water Consortium Sdn Bhd (IWK) today said the black-coloured water found in Sungai Gong, Rawang, was not due to effluent discharge from the Rawang Integrated Industrial Park Sewage Treatment Plant (GBK134), as reported by the media yesterday.
Instead, IWK CEO Narendran Maniam said the company had identified the presence of yellow-coloured non-sewage waste inside the plant’s intake chamber which caused the final effluent to be polluted, turning it to a yellow colour.
“IWK staff at the plant are still monitoring and controlling the sewage intake into the plant.
“We suspect that illegal waste dumping had occurred near our plant, which had caused the substance to flow into the plant.
“As such, we have immediately stopped effluent discharge and started a cleaning operation, which is expected to be completed today.
“Chemical dosing is being carried out to control the situation,” he said in a statement here today.
Yesterday, the media reported that the Selangor Water Management Board (LUAS) had received a report on an incident that the water in Sungai Gong, Rawang, had turned black without the presence of odour, suspected to have been caused by dyes.
On further investigation, LUAS found discoloured and foamy effluent discharge, from area 5 IWK GBK 134 plant, in Rawang Industrial Park.
Disappointed with the claim, Narendran said the matter could confuse the public besides causing them to accuse IWK, although the real source might have been illegal dumping of waste.
“We are very disappointed at being frequently made as an easy target for any water pollution incident such as this one, without detailed inspection or reporting the information completely,” he said, adding that the sewage treatment plant was designed to treat sewage and is unable to treat chemical or other forms of waste.
He added that illegal dumping of non-sewage waste is an offence under the Water Services Industry Act 2006.
