As defined in the Sewerage Services Act 1993, IWK customer is a person, firm, corporate body or other legal entity who is the owner or occupier of any premises located within the operational areas of a Local Authority and uses either an individual septic tank or connected sewerage system that has been handed over to IWK by the National Water Services Commission, Ministry of Energy, Green Technology & Water or a user of any sewerage system as determined by the Water Services Commission.
Commercial premises means any premises used wholly or partly for trade, business, provision of services or any other activity, whether for profit or otherwise.
Government premises mean any premises owned and occupied by the Federal Government, State Government, Local Authority, statutory body established by Federal or State law, a court or tribunal.
Industrial premises means any premises whose principal activity carried out involves the making, altering, blending, ornamenting, finishing or otherwise treating or adapting of any article or substance with a view to its use, sale, transport, delivery or disposal and includes the assembly of parts and ship repairing but does not include any activity normally associated with retail or wholesale trade.
In order for a premise to be billed at the industrial rate, the owner or occupier of the premise is required to complete and return a "Declaration Form" to IWK. The form can be obtained at any IWK office at no charge.
The sewerage billing to Industrial premises is on a monthly basis at RM2.00 per head for premises with septic tank and RM2.50 per head for premises with connected sewerage service.
However, the minimum charge is RM20.00 per month for premises with septic tank and RM25.00 per month for premises with connected service based on minimum headcount of 10 persons. Since the billing is based on head count, owners of industrial premises are required to submit to IWK the "Declaration Form" with the up-to-date head count on a six monthly basis for status as at 30 June and 31 December.
The billing to Commercial and Government premises is on a monthly basis. The monthly charges is a sum of the Basic Charge, which is based on the premises Annual Value; and Excess Charge, which is based on the monthly average water consumption in excess of 100 meter cube. Please refer to the tariff of charges, as approved by the Government, on the flip side of your sewerage bill.
The monthly Excess Charge is only applicable to Commercial and Government premises and chargeable if the monthly average water consumption is in excess of 100 meter cube (m3). The Excess Charge per m3 for Commercial is 30 sen (100-200m3), 45 sen (more than 200m3) and Government is 45 sen (100-200m3), 95 sen (more than 200m3). The water consumption data to compute the charges is obtained from the State Water Authorities/Companies.
The average water consumption is calculated as follows:
The Excess Charges are subject to an annual revision based on the water consumption data for the previous year obtained from Water Operators.
Service Premises with septic tank will receive scheduled desludging service approximately once every two years. However, customers can request for additional desludging services, after the 1st desludging or before the next schedule, at no extra charge other than the monthly charges. Please contact IWK at 03-20832828 or our 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 rectangular metal lids. Occupier of the premises is responsible for the maintenance of the septic tank. IWK is only responsible for desludging the septic tank.
Customer who occupies premises with septic tanks and 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 Water Services Industry Act 2006.
A premise has a connected service, if you see one rectangular metal 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 Water Services Commission, Ministry of Energy, Green Technology & Water.
You will not see IWK staff visiting your premises regularly as our work is mainly at the public sewage treatment plant and maintenance of the network sewer pipelines along the public road. We will be at your service in person if there is back flow of sewage resulting in an overflow of your toilet, bathroom and/or kitchen or overflowing manholes due to blockage along the public sewer pipelines
Throwing or flushing rubbish (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 back flow from occurring, please refrain from throwing or 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 pipelines, 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 RM220.00 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 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 and/or 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
Photocopies of the 1st, 2nd and last two pages from Sales & Purchase Agreement with the names of the purchaser/seller, property address, date of agreement and signatories of all parties concerned are required for any change of ownership. This is to ensure that ownership details are accurately registered in the premise sewerage account.
The monthly Basic Charges for commercial premises is based on the Annual Value of the premises/property. The Local Authorities determine the 'Annual Value', which is defined as 'the estimated yearly rental that can be derived from the said property and is not the same as the property value'.
Based on the property data from Local Authorities, most low-rise (2 - 5 floors) building or shop-house has one Annual Value and thus there will be only one sewerage bill to the building.
Owners of such buildings, who want separate sewerage bills for the respective floors, will have to request the Local Authority to assess the respective floors separately.
Upon getting the Annual Values for the respective floors, customer is required to submit photocopies of the Assessment Bills and also the respective floors' Water Account Numbers to IWK to amend the billings. The revised bills will only commence after all arrears (based on the original billings) are settled in full.
High - rise buildings, regardless of the number of floors, with one Annual Value, one bulk water meter and using common toilet facility will have only one sewerage bill.
The sewerage billing to high - rise buildings with multiple Annual Values, one bulk water meter and using common toilet facility will also has one sewerage bill. The billing is based on the service rendered to the entire building, which has a centralized sewerage system that is connected to the public sewerage system.
Cash payment only can be made at all Pos Malaysia computerised offices and Bank Simpanan Nasional.
Cash or cheque payments can be made at Maybank, Mayban Finance, Public Bank & Finance, Arab-Malaysian Bank & Finance, IWK offices, IWK Head Office at No 44, Jalan Dungun, Damansara Heights, 50490 Kuala Lumpur or IWK pre-paid postage envelope which is enclosed with the Sewerage Bill.
On-line payments can be made through "MBf Click or Call & Pay" for Mastercard holders only and "Maybank2U.com.my" for Maybank Account holders only.
The occupier i.e. owner or tenant of any premises to which sewerage services has been provided by IWK shall be liable to pay the sewerage charges.
However, if the occupier or tenant of the premises failed to fulfill this obligation, the owner is jointly liable to pay the sewerage charges, as stipulated in the Sewerage Services Act, Regulations of Charges 11, "the owner and occupier of a premises to which sewerage services has been provided by IWK under these Regulations shall be jointly and severally be liable to pay the sewerage charges, provided the owner of the premise shall, in the absence of any agreement to the contrary, be entitled to recover from the occupier (tenant) of the said premises any such charges paid by the owner/landlord at the time of occupation by the occupier (tenant)"
