KLANG Valley folk were spared another water supply disruption, thanks to the quick action by Selangor Water Management Board (Luas), which mitigated the inflow of odorous soot into the waterways of Sungai Kuang.
The soot was from a fire at a plastic processing factory at Sonstar Industrial Park in Rawang.
Yesterday, in its Facebook page, Luas said the odour pollution in Sungai Kuang was measured at three TON (threshold odour number).
Subsequent tests at three locations showed readings of less than one TON each, while at Sungai Kundang, the reading was at 0 TON.Luas said continuous monitoring would be conducted to ensure no odour pollution in Sungai Selangor.
The water management board also reported that the factory had been issued a water protection order under Section 122 of the Selangor Water Management Authority Enactment 1999.
The order requires the factory owner to cease from further acts that can pollute the river. Non-compliance will subject the factory owner to a fine no more than RM50,000 or jailed not exceeding one year or both, upon conviction.
The factory owner also faces further fines of RM3,000 for each day the offence continues until the order is revoked.
Selayang Municipal Council (MPS) was also said to have issued a public nuisance notice to the owner of the premises and requested that cleaning work be carried out immediately.
The timely intervention by Luas was made possible with the establishment of its Skuad Pantas which performs 24-hour monitoring of Sungai Selangor, Sungai Langat and Sungai Klang.
Selangor environment, green technology, science, technology and innovation and consumer affairs committee chairman Hee Loy Sian, in a statement, said Luas was alerted of the situation when its round-the-clock monitoring team was informed of the incident from the Selangor Fire and Rescue Department at 10pm on Saturday.
Following checks at the site, it was found that fire waste was flowing into the drains and waterways of nearby Sungai Kundang, a tributary of Sungai Kuang.
Hee said site images from Luas’ social media page showed a thick, black, lava-like substance smothering the water surface.
A response unit comprising personnel from the Luas Ops Water Source surveillance team, Air Selangor and MPS built an earth bund to prevent further inflow of the soot into the river.
Hee said the barricade effectively stopped the flow of odourous pollution to Sungai Sembah, which lead directly to Sungai Selangor where the Rantau Panjang Water Treatment Plant is located.
The distance of the factory and water treatment plant, he added, was only about 33km.
Air Selangor has placed 43 bags of activated carbon at the source of the fire waste to absorb toxins and odour.
Batu Arang Fire and Rescue Station senior Fire Officer 2 Aminuddin Derani, who was on duty at the scene, said seven firefighting teams from Sungai Buloh, Bestari Jaya, Rawang, Subang, Sungai Pinang and Petaling Jaya were called to the scene.
The factory fire was put out at about 4.30am, he said, adding that the cause of the fire was still not known.
He said no one was injured in the fire but 90% of the factory was damaged, adding that foam had been used as a retardant.
