How to Pay Your Water Bill Online in Saudi Arabia (NWC)
Water and wastewater bills in most Saudi cities come from the National Water Company (NWC). Paying them online is simple once you know two things: your reference number and NWC’s SADAD biller code. This guide covers the official payment route, where to find your bill, and what NWC offers if a bill has become overdue.
Quick answer
Get your invoice or reference number from the Ehsal platform or the NWC app, then open your bank app, choose SADAD Bill Payments, enter biller code 138 and your reference number, review the bill and pay. The National Platform lists the service as free (my.gov.sa).
Key takeaways
- SADAD biller code for NWC: 138.
- Channels: internet banking, mobile banking or ATM.
- Service cost: listed as free on the National Platform.
- NWC app: more than 35 services, according to NWC.
- NWC call centre: 8004411110 (NWC).
How SADAD water bill payment works
The National Platform describes this service as paying NWC water bills through approved bank channels (internet banking, mobile banking and ATMs) using the biller code and the invoice reference number, via the SADAD payment system.
That means you do not need a separate NWC wallet. Any bank that offers SADAD Bill Payments can settle the bill, and the payment is linked to your account by the reference number.
Step by step
Paying an NWC bill through your bank
1
Find your reference number: on the Ehsal platform or in the NWC app.
2
Open your bank: internet banking or the mobile banking app.
3
Choose SADAD Bill Payments: in the payments menu.
4
Enter biller code 138: this identifies NWC.
5
Enter your reference number: then review the invoice details shown.
6
Confirm and pay: and save the receipt if you want a record.
These are the steps the National Platform lists for the service (my.gov.sa).
Tip
Save NWC as a registered biller in your bank app the first time. Next month you only pick it from your list instead of typing the code and reference again.
Where to see your bill first
Before paying, it helps to see what you are paying for. NWC’s mobile app is its main self-service channel; NWC says the app includes more than 35 services for water and sanitation customers across Saudi cities and governorates.
NWC’s website also runs an e-branch. Its service catalogue lists a “bills list” service that shows your bills after you log on through its e-channels.
If you also manage your electricity account online, the process is similar in spirit. Our guide to checking and paying your electricity bill online covers that side.
If a bill is overdue: instalments and partial payment
NWC publishes an instalment and partial payment page for customers with overdue consumption bills. It says the aim is to help you settle what is owed and to re-open a meter closed for non-payment, so water arrives through the network rather than by tanker.
According to NWC:
- instalment plans appear in the NWC app or e-branch once your bills reach an amount eligible for instalments;
- you can instal through NWC itself, or through your credit card with several listed banks (Al Rajhi Bank, Bank Aljazira, Riyad Bank, SAB, Saudi Investment Bank and Emirates NBD) for amounts from SAR 500;
- as another option, you can make a partial payment of half or more of the bill amount.
| Option | When it fits | Where |
|---|---|---|
| Full SADAD payment | Normal monthly bill | Your bank app, biller code 138 |
| Partial payment | You can pay at least half now | NWC channels |
| NWC instalment plan | Overdue bills at an eligible amount | NWC app or e-branch |
| Credit card instalments | Overdue amounts from SAR 500 with listed banks | Through the bank, per NWC |
Note
Conditions for instalments are set by NWC and may change. Check the details shown in your NWC app before choosing a plan.
Staying safe when paying bills
Warning
Pay only through your own bank app, the official NWC app or official NWC channels. Ignore messages with payment links that claim your water will be cut off today; check your balance in the NWC app instead.
A good habit for renters: confirm with your landlord whose name the water account is in and who pays it. If you are moving into a new flat, our guide to the National Address explains why a correct address matters for services.
