How to Pay Your Water Bill (NWSDB) Online
Pay your National Water Supply and Drainage Board (NWSDB) bill from your phone in under a minute, with an instant receipt. Here is what you need and how it works.
Your water bill arrives every month, and so does the question of when you will find time to pay it. A trip to a payment counter means travel, queues, and cash. With Pay&Go, you can pay your water bill online from your phone, any time of day. This guide covers NWSDB water bill payment step by step, so you can finish your water supply bill payment in a few taps.
What You Need Before You Start
Keep your NWSDB account number handy. You will find it on your water bill. Check it digit by digit, because a wrong number is the most common reason a payment does not match.
You also need a bank account linked to the Pay&Go app.
Steps to Pay Your Water Bill Online
Wondering how you can pay your water bill online? Follow these seven steps.
- Step 1: Open the Pay&Go app, tap Utilities, then select NWSDB.
- Step 2: Enter your NWSDB account number. Your account details appear straight away, including the account holder name and the amount due.
- Step 3: Check that the name and amount match your bill, then tap Next.
- Step 4: On the Payment screen, under Pay by, choose your bank account.
- Step 5: Check the Amount. It shows your total due, and a small line below it shows any service charge, so you know the full total before you pay.
- Step 6: Tap Pay. Your payment is completed.
How to Check Your Water Bill Online in Sri Lanka
Many people want to check their water bill before they pay. In Pay&Go, the check is part of the payment. After you enter your account number, the app shows your account details and the amount due.
Compare them with your paper bill. If the name and amount match, you can carry on. This works as a quick NWSDB bill check without a trip to an office. If something looks wrong, stop before you tap Pay and contact NWSDB using the details on your bill.
Why Use an App for NWSDB Online Bill Payment
Water bill payment online in Sri Lanka should be quick. An NWSDB online bill payment app should save you time, not add steps. Here is what you get with Pay&Go:
- No queues: Pay from your phone, wherever you are.
- No cash: Pay straight from your bank account.
- Proof of payment: Your receipt appears as soon as the payment goes through.
- One app for many bills: Handle your utilities and other bills in the same place.
Keep Your Receipt for Your Records
Every successful payment gives you a receipt. Save it as a record of the payment of your water bill, with the date.
A simple habit helps. After each payment, take a screenshot of the receipt and keep it in a folder on your phone. If you ever need to show that a past water bill was settled, you will have it ready.
Why Pay Your Water Bill on Time
Your bill shows a due date. If a bill stays unpaid, the water supply can be disconnected, and getting reconnected may cost extra. Check your bill for the exact due date and any charges that apply.
Paying from your phone as soon as the bill arrives takes that worry away. For official information, visit the NWSDB website.
If Something Does Not Go Through
Most issues come down to two things:
- The account number is wrong. Re-check it against your bill and enter it again.
- The OTP did not arrive. Make sure you are using the mobile number registered with your bank, and that you have signal.
