Spills/Overflowing Manhole

Occasionally, the flow of wastewater in the underground public sewerage pipelines is blocked by rubbish or solid waste/objects. When this happens, the wastewater will overflow at the public manholes. IWK is responsible for clearing the blockage in the sewerage pipelines through the manholes using high pressured water hoses, high powered vacuum and/or mechanical rodders within 24 hours from the time of notification. You can help to prevent this overflow by not disposing any solid waste in the toilet or the sewerage system within your premises.



 

Missing Manhole Cover

Areas, which have a sewerage system that is connected to a public sewage treatment plant would have "manholes" along the roads or sidewalks. Public manholes are covered with a round metal cover made of cast iron and an embossed with "JPP" (Jabatan Perkhidmatan Pembetungan), "Indah Water" or Local Authority's logo. There have been many cases of the cover being stolen by unscrupulous individuals. New manhole covers come with a hinge and lock to prevent theft. IWK will replace the missing cover within 12 hours from the time of notification.

 


 

Blockage Within Premises

The toilet will overflow or spill, if there is a blockage in the internal sewerage pipelines within the premises or between the premises to the nearest public manhole. This is usually caused by solid waste/objects blocking the passage in the pipelines. Clearing of the blockage will be performed through the drainage pipes in the "inspection chamber" or the internal sewerage pipelines within the premises. Inspection chamber can be identified from the one rectangular metal cover, which is usually located outside the premises either in front, at the back or side of the premises.

The service is rendered within 48 hours from the time of notification. (Advance payment is required before the service is rendered)



Blockage at Public Sewerage Pipelines

IWK is responsible for maintaining the network of public sewerage pipelines for areas, which have a sewerage system that is connected to a public sewage treatment plant. The most common problem encountered is blockage caused by rubbish/solid waste, grease, rubbles, grit, and occasionally damaged pipes. IWK will rectify the problem within 24 hours depending on the type of objects blocking the passage using high pressured water hose, high powered vacuum and/or mechanical rodders. If there are broken pipes, IWK will replace the pipes and ensures minimal inconvenience to customers.
