KWSB Duplicate Bill Online Check 2026

If you’ve lost your paper copy, getting a KWSB duplicate bill online only takes a few minutes, and you don’t need to visit an office to do it. This guide gives you the current, official way to do it, plus every backup option in case the website is slow.

KWSB Is Now Called KWSC

Here’s something worth knowing before you start searching. The Karachi Water and Sewerage Board (KWSB) was renamed to the Karachi Water and Sewerage Corporation (KW&SC). Most people still call it KWSB out of habit, and that’s fine, but the official portal and app now run under the KWSC name. Keep that in mind if you come across old links or screenshots that don’t match what you see today.

What You Need Before You Start

You only need one thing: your consumer number. It’s an 11-digit number printed on any of your previous KWSC bills, usually near the top, close to your name and address.

If you can’t find an old bill and don’t know your consumer number, your fastest option is to call KWSC directly or visit a Customer Service Center, both listed further down this page.

How to Check Your KWSB Duplicate Bill Online

  • Go to the official KWSC website: www.kwsc.gos.pk
  • Look for “Get Your Bill” on the homepage. This is the section for viewing and downloading your bill.
  • Enter your 11-digit consumer number in the field provided.
  • Submit the request. Your current bill details should appear on screen, including the amount due and the billing period.
  • Download or print the bill for your records or for paying at a bank.

If the website is slow or not loading, this usually happens during peak hours or right after bills are generated. Try again after some time, or use one of the alternatives below.

Other Ways to Get Your Duplicate Bill

KWSC has confirmed these additional options through its official channels:

  • KWSC Unified App: Download the app, register with your details, and request your bill from there.
  • KWSC Consumer Centers: Visit in person with a valid ID if you’d rather deal with someone face to face.
  • Phone: Call KWSC’s helpline at 1334 for help with your bill.

KWSC Contact Details

For anything the website can’t sort out, here are KWSC’s official contact details:

  • Head Office: 9th Mile Karsaz, Main Shahrah-e-Faisal, Karachi-75350
  • Phone: (+92) 021 111 597 200

A Few Things to Know About Your Bill

KWSC generates water and sewerage bills on a bimonthly basis, meaning once every two months rather than monthly. Your consumption is measured in units, and charges can vary depending on which part of Karachi you’re billed from. If a charge on your duplicate bill looks wrong, don’t guess. Use the complaint option on the KWSC website or call their helpline to get it checked.
