SHAH ALAM, Sept 1 — The Subang Jaya City Council (MBSJ) will issue notices to businesses in SS15 found making unauthorised sewerage connections that risk damaging the system, The Star reported.
Subang Jaya assemblyman Michelle Ng said inspections found some property owners had illegally channelled kitchen waste and rainwater into the main sewer line, causing frequent blockages and overflow.
“We are aware that some property owners made unauthorised connections from kitchens (to the sewerage network) as well as rainwater downpipes directly into inspection chambers.
“The oil from kitchens is one of the main causes of blockages in the sewerage pipes, while (wrongly channelled) rainwater often results in overflow as the capacity of sewerage pipes cannot cater to rainfall.
“This matter has been discussed with MBSJ, which will conduct an inspection and issue notices to the relevant premises to redirect those connections,” she said during a site visit yesterday.
This follows the completion of a RM2.74 million sewer pipe replacement project in SS15, funded by the National Water Services Commission (SPAN) through its Sewerage Capital Contribution Fund and carried out by Indah Water Konsortium (IWK).
The 18-month project replaced more than 400 metres of ageing main sewer lines and 150 metres of connecting pipes serving 46 shoplots, while IWK also upgraded the drainage system.
Ng said the project, completed on July 10 after delays due to soil stability works, will benefit around 40,000 residents and workers.
MBSJ councillor Balachandran Naicker, who was also present, said the council would draft new guidelines on grease trap installation and maintenance, noting that many eateries either use undersized traps or none at all, worsening the problem.
SPAN senior director for regional operations Mohd Jalaludin Sulaiman reminded business owners that discharging effluent into public sewerage systems is prohibited under Section 61 of the Water Services Industry Act 2006.
