Bill Not Showing Online? Try This
- Check that you entered the full Consumer Number correctly, without spaces.
- New bills may take a few days to appear online after they are issued.
- If the website is slow, try again later or use the KW&SC Unified App.
- If the bill still does not show, call 1334 with your consumer number.
Why Is My Water Bill Higher Than Usual?
- Arrears: unpaid amounts from earlier bills are added to the new bill.
- Late payment surcharge: paying after the due date increases the amount.
- Wrong category: if your property is billed in the wrong category or size, file a billing complaint.
- Leakage: report leaks to KW&SC so water is not wasted.
Tips for Karachi Water Consumers
- Save your Consumer Number in your phone so you can check your bill any time.
- Save each paid bill as PDF as proof of payment.
- Report water theft and illegal connections, which reduce supply for everyone.
- Use water carefully in summer, when shortages are common.

How to Check KWSC Bill on Mobile
- Open Chrome or any browser on your phone and go to kwsc.gos.pk.
- Tap Get Your Bill at the top of the page.
- Enter your Consumer Number/ID and tap Get Bill.
- Use your browser’s Share or Print option to save the bill as PDF, or take a screenshot of the amount and due date.
You can also install the KW&SC Unified App so you do not need to open the website every month.
Keep a Record of Your Water Bills
Save every paid water bill as a PDF or photo. Paid bills are often needed as proof when you sell or rent out property, apply for a new connection, transfer the connection to a new owner, or file a billing complaint. A record of past bills also helps you see quickly if a new bill is unusually high, so you can complain on time before the due date.
