Overview
- Residents in Gulmohar Park, Hauz Khas, Sarvodaya Enclave, Green Park and Malviya Nagar reported foul-smelling, black or sewage‑tainted tap water and intermittent supply this summer, with some people falling sick and relying on private tankers.
- Delhi Jal Board field teams have dug up and repaired local leaks, coordinated tanker relief with RWAs and begun flushing affected pipes while collecting samples for testing.
- In mid-June the DJB installed a pilot online water analyser in Gulmohar Park to track pH, TDS and disinfectant levels in real time and officials say the system may be expanded if the trial succeeds.
- Officials and experts point to clear technical causes: roughly 5,500 km of Delhi’s pipelines are over 30 years old, treatment-plant output has fallen short this summer by an estimated 40–100 MGD on many days, and low or erratic pressure lets sewage enter corroded joints or damaged service connections.
- Longer-term fixes being planned include phased pipeline replacement, better network mapping, continuous pressurisation and wider digital monitoring to cut leak losses and prevent repeat contamination that is already raising health and expense burdens for residents.
