- Follow current public-health advice if you suspect drinking-water contamination
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
