Sewage Overflow in Karachi — Who to Call & How to Get It Fixed

Sewage Overflow Emergency Guide

Sewage overflows are a health emergency. Here's the fastest way to get it fixed.

Emergency Numbers

Service	Number	Notes
KWSB Emergency	118	First call — sewage is KWSB jurisdiction
CM Helpline	1339	Escalation if KWSB doesn't respond
Sindh EPA	080025786	If near food markets, schools, hospitals
Sindh Food Authority	0800-02345	If sewage reaches food preparation areas

Step-by-Step Process

Immediate:

Call KWSB at 118 — report as sewage emergency

Give exact location, nearest manhole or nala

Get complaint number

If near sensitive areas (food markets, schools, hospitals):

Also call Sindh EPA and Sindh Food Authority

They can issue notices faster than KWSB in high-risk areas

Follow up:

Call 118 again after 12 hours with complaint number

If no response in 24 hours, escalate to 1339

Protect Yourself

Don't walk through sewage water — hepatitis, typhoid, and skin infections are real risks

Keep children away — sewage water near playgrounds is a health emergency

Don't try to unblock manholes yourself — gas buildup in manholes kills people every year in Karachi

Boil drinking water if sewage is near water supply lines

Why Sewage Overflows Happen

Blocked nalas (drains) — garbage clogs the drainage system

Burst sewer mains — aging infrastructure, especially in older areas

Monsoon overload — Karachi's drainage can't handle heavy rain

Illegal construction over nalas — blocks natural drainage paths
