A Karachi consumer number is a mix of letters and digits, 12 characters long — for example H0020635000A, the example KWSC itself shows on its form. Type it exactly as printed on your old bill, with no spaces.
Where to find your consumer number (letters + digits)
Your consumer number is printed on your old KWSC / KWSB bill. It starts with a letter and is followed by digits and a final letter, like H0020635000A. Follow the example shown on the official form if it asks you to leave out the last letter.

Download and print your Karachi duplicate bill
The bill on your screen is a full duplicate of the paper original — same consumer number (letters + digits), same amount, same due date. It is accepted everywhere the original is: at bank counters, in mobile wallets and for your own records. Use the Print option on the bill and choose “Save as PDF” if you want a file to keep or to send to a tenant. If the paper bill never arrived at your house, this duplicate is the copy to pay against; there is no need to visit the KWSC Karachi office for it.
What your Karachi bill looks like
This is the layout of the bill KWSC Karachi issues — the same design appears on the printed bill and on the duplicate you open from the checker. The name, number and amounts in this picture are sample data. Your own consumer number (letters + digits) sits in the highlighted box, exactly where it is on your real bill.
About KWSC Karachi
Karachi’s water was run by the KWSB from 1983 until Sindh converted it into the Karachi Water and Sewerage Corporation (KWSC) under a new law in 2023, with the Mayor of Karachi chairing its board. KWSC reports about 1.29 million domestic and commercial consumers, plus some 8,000 bulk consumers (KWSC figures, 2026). In February 2026 it launched a single app for complaints, bill payment and tanker booking.
Why is my Karachi bill high this month?
Before anything else, look for arrears on the bill — an unpaid balance from an earlier month is the most common reason a Karachi bill suddenly looks big. After that, check your home: a leaking tank valve, a running flush or a cracked underground pipe wastes water around the clock. A wrong reading can also slip in. On unmetered connections the charge is fixed, so the bill does not fall in a month when you used less. If none of these explains it, ask KWSC Karachi to check the bill before you pay the extra — call 021-111-597-200 or follow the routes on our complaint page. A real mistake can be corrected. For the full checklist, read our guide on why a WASA bill comes out high.
Billing month, due date and surcharge in Karachi
KWSC Karachi bills are monthly, and every bill names the month it belongs to. The paper copy reaches different streets on different days, but that does not change anything that matters: the date printed on the bill as the due date is the last day to pay at the lower amount. From the next day, the higher “payable after due date” figure applies, because the late surcharge has been added. If a month’s bill never reached your house, check it online in the first week of the month instead of waiting — a late paper bill is not accepted as a reason by any billing office. And if you miss a month completely, the unpaid amount does not disappear. It returns on the next bill as arrears, which is why one missed month makes the following bill look so heavy. Our due date and surcharge guide explains the two amounts printed on every bill, and how to stay on the lower one.
New WASA water connection in Karachi
A new connection starts at the KWSC Karachi office (KWSC head office, 9th Mile Karsaz, Shahrah-e-Faisal, Karachi), not online. Take your CNIC and your property documents — registry or allotment papers, or a rent agreement if you are a tenant applying with the owner’s permission. The office issues a demand note with the current connection charges; we do not print a fee figure here because the authorities revise these charges and an old figure would mislead you. Once the connection is installed, your first bill carries the consumer number (letters + digits) that you will use for every online check from then on.
Direct link: the official KWSC Karachi online system is at www.kwsc.gos.pk — new-connection requirements, any application form and office contacts are published there, so check it before you visit. If an online application route is offered for your area, it will be on that system, and the office counter remains the fallback for everyone. Our guide to a new WASA water connection walks through the full process.

My Karachi bill is wrong or too high. What do I do?

Common Karachi problems, quick answers
No water, or weak supply
Call KWSC Karachi on 021-111-597-200 and note the complaint number you are given. Supply runs to a schedule by area, so ask for your street’s timing while you have them on the line.
The bill looks wrong
Check the arrears line first — most sudden jumps are an old balance, not this month’s water. Still wrong? Use the complaint routes and take your last bills and receipts.
New connection or name change
Both start at the office (KWSC head office, 9th Mile Karsaz, Shahrah-e-Faisal, Karachi). Take your CNIC and property papers; the office issues a demand note showing the current charges before any work begins.
Ways to pay in Karachi
Bank app or internet banking
Pay through 1-Link in almost any Pakistani bank app. For Lahore, type the prefix 100059 before your 8-digit account number.
Scan the QR code
Lahore bills carry a printed QR code. Scan it in the Bank Alfalah, Standard Chartered or HBL app and the amount fills itself in — no typing, no wrong number.
JazzCash or Easypaisa
Open the wallet, choose bill payment and the water category, pick your city authority, and pay against the same consumer number you checked with.
Bank counter or NADRA
Prefer cash? Any bank branch and NADRA e-Sahulat take WASA bills. Remember: NADRA takes the full amount only, never a part payment.
Before you visit the KWSC Karachi office
Some work still happens at a counter — a new connection, a name change, a correction in the record. A prepared visit is a short one:
- Carry your CNIC and a photocopy, plus your latest bill, paid or unpaid.
- For anything about ownership — name change, new connection, a record correction — take the property papers too: registry, allotment letter, or the rent agreement if you are a tenant applying with the owner’s consent.
- Go in the morning. Counters are quieter early, and the day’s token list fills up by midday.
- Whatever you submit, ask for the diary or token number and keep the stamped copy. It is your proof, and it turns every follow-up visit into a short one.
- Before you pay any demand note, read it line by line and ask what each charge is for. The current charges are the ones printed on that note — not a figure from a website or a neighbour’s old bill.
Keeping your Karachi bill under control
On an unmetered connection the monthly charge is fixed by plot size, so careful water use does not shrink that bill directly. What discipline does stop is the two things that genuinely push bills up: charges that grow around a working meter where one exists, and the arrears spiral that starts the first time a bill is skipped. The habits that matter:
- Fix the roof tank’s ball valve. An overflowing tank is the most common silent waste in Pakistani homes — and the first thing to rule out when a metered bill climbs.
- Listen at night. If the tank keeps refilling while every tap is closed, water is escaping somewhere. Find it this month, not after the next bill.
- Pay when the bill arrives, not on the last day. Queues, app failures and portal rush all cluster at the deadline, and the surcharge does not care whose fault the delay was.
- Keep every paid bill and payment screenshot for a year. Records settle almost every dispute at the counter in minutes.
