Payments to IWK

e-Bill is an electronic billing that delivers your bills electronically to your registered email address. It eliminates the risk of losing bills in the mail and the hassle of managing physical paper copies. 

Here’s how e-Bill works:

  • You can register e-Bill at IWK Customer Portal or through the Indah Water mobile app

  • Each Sewerage Account Number can only be linked to a single e-Bill, which is delivered to a single email address. However, you can register multiple Sewerage Account Numbers to the same registered email address.

  • Once you have registered for e-Bill, you will no longer receive hardcopy bills in the mail.

  • Soon, there will be a minimum fee imposed on each request for a hard copy bill.

e-Bill offers a convenient and eco-friendly way to receive and manage your sewerage bills electronically, reducing the need for physical paper bills.

According to Regulation (9) of the Water Service Industry (Sewerage Services Charges) Regulations 2022, it states that:

"Any person who sells or transfers any premises in respect of which sewerage services charges have been incurred for sewerage services provided by the services licensee, shall continue to be liable for the payment of all sewerage services charges payable in respect of the premises unless prior notice has been given to the service licensee in relation to such sale or transfer."
"Nothing in these Regulations shall affect the liability of the purchaser or transferee to pay the sewerage services charges in respect of the premises referred to in subregulation (1) or affect the right of the service licensee to recover the sewerage services charges from the purchaser or transferee."

In light of the above, IWK will no longer entertain requests to apportion outstanding charges between the vendor and purchaser, nor can we waive the sewerage charges prior to the sale and purchase agreement. It’s essential for all parties involved in the sale and purchase of the premises to ensure that any outstanding bills are settled during the transaction. Failure to do so means that IWK will recover the outstanding charges from the purchaser as mandated by the regulations.


The above also applies to rental premises, whereby owners will be liable for any outstanding incurred by their tenants.

You are encouraged to leave the excess payment to off-set future charges or request to transfer to another Sewerage Account Number. If neither option is available, then you may request for a refund.

You can request for an instalment plan for your outstanding sewerage bills. However, please note that this request is subject to approval, and there are certain requirements to be met.

Here’s how you can request an installment plan:

  • Email / a written request: Send an email or written request to care@iwk.com.my or complete the Request for Instalment Form at any of our counter services

  • Indicate Amount or Period: In your request, indicate approximately the amount of each instalment or the number of monthly instalment periods.

  • Compliance: It’s important to adhere to the agreed instalment plan diligently. Defaulting on any monthly instalment payment will nullify the agreed instalment plan, and IWK reserves the right to demand full settlement of the remaining outstanding amount as a lump sum payment without any further notice.

IWK appoints Debt Collection Agencies (DCA) to assist our collection activities which may include contacting customers via calls, SMS, sending notices, or making visits to customer premises. Your account may be automatically assigned to an authorized DCA for collection activities, if you fail to clear your outstanding sewerage charges.

If you are in doubt, please log in to IWK Customer Portal or Indah Water mobile app to view your Sewerage Account details and status. Should there be an outstanding, please proceed to make full settlement via our IWK Customer Portal or Indah Water mobile app.

Your name is listed in CTOS if you have defaulted on your outstanding sewerage bills, even after receiving several reminders from IWK.

To have your name removed from IWK CTOS tagging, it is necessary to settle any outstanding sewerage bills, Letter of Demand (LoD) charges, and CTOS fees. Once IWK receives full settlement, including LoD and CTOS fees, we will promptly inform CTOS Malaysia to delist your name.
