KW&SC Water Complaint — Step by Step

The Karachi Water & Sewerage Corporation (KW&SC) provides an official complaint portal and customer helpline. Start there so you receive a trackable record.

How to File Effectively

Step 1: Use the KW&SC portal or call 111-597-200. Save the complaint number and the mobile number used to register it.

Step 2: Be specific. Don't say "no water." Say:

  • "Block 7, Gulshan-e-Iqbal, Street 14 — zero supply since Monday March 10"
  • "Approximately 200 households affected"
  • "Last supply was 3 days ago, tanker came once on Tuesday"

Step 3: State the scope accurately. If multiple homes are affected, name the street or block and estimate only what you can verify.

Step 4: Track the same complaint. Use the portal or helpline and keep dated notes rather than opening duplicate reports immediately.

Step 5: Add a 1339 record if needed. Reference the existing KW&SC complaint number and describe any immediate public-health risk.

If You Need a Tanker

When the pipes are dry, here are your options:

  • Use KW&SC's official tanker-booking link from its website and confirm the current process there.
  • For any private supplier, confirm the source, total price and delivery terms before paying.
  • Do not publish a household phone number or precise home address in a public Mashvara report.

Report on Mashvara

Document your water issue on Mashvara with a current photo and approximate area. This creates a public community record but does not replace the official KW&SC complaint.
