Since March 2018, there will no monthly bills issued to Domestic IST customer. Customer has to pay cash RM144 through Payment on Service (POS) method during desludging work. Warranty period is 30 days after desludging date. Should there any request of desludging service within this warranty period, no charge will be imposed.

Please contact IWK offices nearest to you, if your premise septic tank needs desludging service.
Septic tank is normally located outside the premises under the ground at the side, rear or in front of the premises and is covered with 2 - 4 metal lids. Occupier (owner/tenant) of the premises is responsible for the maintenance of the septic tank. IWK is only responsible for desludging the septic tank.
Customer (occupiers/owners) who refuses IWK's scheduled desludging service of their premises' septic tank, shall be guilty of an offence and shall, on conviction, be liable to a fine as stipulated in the Water Services Industry Act 2006.
Premises, which are connected to the public sewage treatment plant, will be billed RM32.00 once every four months or RM8.00 per month. Your premise has a connected service, if you see one rectangular metal lid/cover, which is an inspection chamber, outside the premises either at the side, rear or in front. The entire area of your premises has connected service if you see manholes along the road connecting the premises to a public sewage treatment plant. In the manhole are sewerage pipelines, which also serves as a checkpoint to identify sewerage problems and clearing of any blockage. It is an offence to open the public manhole without proper authorization from IWK or National Water Services Commision, Ministry of Water, Land and Natural Resources.
You will not see IWK staff visiting your premises regularly as our work is mainly at the sewage treatment plant and maintenance of the public sewer pipelines along the public road. We will be at your service in person if there is back flow of sewage into your premises or overflowing manhole due to blockage along the public sewer pipes.
Throwing or flushing rubbish's (sanitary napkins, diapers, refuse or solid waste) into the toilet and/or septic tank/inspection chamber will clog your internal and public passage of the sewer pipelines. This will cause the wastewater to back flow into the toilet, kitchen and bathrooms. To prevent this from occurring, please refrain from throwing / flushing solid wastes (especially sanitary napkins and diapers) into the toilet, septic tank or inspection chamber.
In the inspection chamber are sewage outlets linking the premise sewer pipelines to the public sewer pipelines and is mainly used for checking and clearing of any blockage. For clearing of blockages along the public sewer pipes, customers do not have to pay for the service, as it is the responsibility of IWK to maintain it.
However, for clearing of blockages along the private (internal) sewer pipelines, which is the sewer pipelines from the premises linking to the public sewer pipelines, customer has to pay RM180.00 for each service. This service is on a 'cash-on-delivery' basis. Please insist on payment receipt upon making payment.
In the event, if the internal sewer pipelines are damaged, the occupier (owner/tenant) will have to engage a private contractor, at his or her own expenses, to replace the damaged internal sewer pipelines. IWK will provide the contact numbers of private contractors on request.
A premise, which has been vacant for a minimum period of 6 months, is eligible for a waiver of the sewerage charges. However, customer has to provide documentary evidence in the form of a Water Statement of Account showing minimum of 3m3 water usage during the vacant period and/or deposit payment/last payment receipt from the Water Authority/Companies on the termination/installation of water supply.
Alternatively, the Statement of Account or documents from Tenaga Nasional Berhad showing nil usage or no power supply during the vacant period is also acceptable. The documentary evidence is to be submitted to IWK periodically throughout the vacant duration.
Premises declared low-cost by the Local Authority will be billed RM8.00 once every 4 months or RM2.00 per month. Please send us a photocopy of the Assessment Bill and/or letter from the Local Authority for our further action.
