Your KWSB water bill does not need a bank queue. You can open it on the official KW&SC website and pay it there with JazzCash. Or you can print it and pay at a counter. This guide shows both routes, step by step, for Karachi homes.

Everything below comes from the official Karachi Water and Sewerage Corporation website. KWSB is the old name. The board is now called KW&SC, so you will see both names on bills and apps.

1. Your consumer number

It is printed on your water bill. Type it without the last letter.

2. A JazzCash account

Only for paying on the KW&SC site. It must be registered on your own CNIC.

3. Two minutes

Opening the bill and paying it is quick if the number is right.

Route A: pay on the KW&SC website

This is the official way. The money goes from your JazzCash wallet straight to your water bill.

  1. Open kwsc.gos.pk and tap Get Your Bill at the top of the home page.
  2. A box called "Get Your Water Bill" opens. Type your number in the Consumer Number/ID field. Use letters and digits only. Do not add spaces or dashes, and leave out the last letter.
  3. Tap Get Bill. Your current bill opens on the screen.
  4. Check the name and address. Make sure it is your house and not a neighbour's.
  5. Tap Pay Via JazzCash.
  6. Enter your 11-digit JazzCash mobile number, like 03001234567.
  7. Enter the last 6 digits of your CNIC in this form: 12345-6. The site adds the dash for you.
  8. Tap Pay Now and wait. Keep your phone with you in case JazzCash asks you to confirm.

When it works, you will see this message: "Thank you! Your bill has been paid successfully." The page then reloads your bill.

The CNIC must match the wallet

KW&SC says the CNIC "should be the one registered with the provided JazzCash Wallet/Account, otherwise the transaction will fail." So use your own wallet with your own CNIC. If a family member pays, they should enter their own mobile number and their own CNIC digits. The water bill can be in anyone's name.

Route B: print the bill and pay at a counter

No JazzCash? You can still use the same official page.

  • Open your bill as in steps 1 to 3 above.
  • Tap Download Bill. You get a PDF of your bill.
  • Print it. The printed copy shows the barcode and your Consumer ID.
  • Take it to a payment point. The KW&SC home page has a Payment Locations tab in its "Customer Service & Operations Locations" section. Use it to find one near you.

The bill page itself says: "This is a digital bill generated electronically." So you do not need a stamped paper copy from an office.

Read these lines before you pay

The online bill has a lot of boxes. Only a few matter when you pay.

Line on the billWhy it matters
Due DatePay on or before this date to pay the lower amount.
Payable Before Due DateThe amount to pay if you are on time.
Payable After Due DateThe higher amount after the due date. It includes the surcharge.
Outstanding ArrearsOld unpaid amounts. If you already paid them, keep your receipt.
Charges tableShows water, sewerage, conservancy and fire charges, each with current, arrear and total columns.

How to check that your payment reached KW&SC

Do not just trust the SMS. Look at the bill itself.

  • ✔ Right after paying online: open your bill again. If it is paid, the JazzCash button changes to Bill already paid.
  • ✔ For older months: scroll to Billing History (Last 12 Months). It lists each month with the amount billed, the amount paid and the payment date.
  • ✔ After a counter payment: keep the stamped receipt. Check that the consumer number and amount on it match your bill.
