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."

IWK will no longer entertain requests to apportion outstanding sewerage charges between the vendor and purchaser. Additionally, we are unable to waive any charges accrued by the previous owner (vendor/transferee). It is the responsibility of all parties involved in the sale and purchase of a property to ensure that any outstanding IWK bills are fully settled during or prior to the completion of the transaction. In accordance with prevailing regulations, IWK reserves the right to recover any unpaid charges from the current owner (purchaser) of the premises.


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.
