Delhi Water Crisis: What's Behind Supply Disruptions In Dwarka, Rohini And How Long Will They Last?

Delhi Water Crisis: The national capital is currently facing a major water supply disruption, with six of its nine major water treatment plants either non-operational or functioning below capacity as of Friday. Authorities have warned that the shortage is likely to continue into early February.

The water crisis stems from a sharp surge in ammonia levels in the Yamuna River, coupled with reduced raw water supply from neighbouring Haryana.

Delhi Water Crisis: Why Capital Is Facing Water Supply Disruption?

The national capital is facing a water supply crisis due to two concurrent issues:

Sudden Spike In Ammonia Levels In Yamuna

- First, alarmingly high ammonia levels in the Yamuna River have forced the Wazirabad Water Treatment Plant (WTP), which normally processes 138 million gallons per day (MGD), to shut down entirely, Hindustan Times reported.

- Ammonia levels, which usually should not exceed 1.0 ppm, recently surged beyond 3 ppm, making the standard chlorination process unsafe.

Reduction In Raw Water Supply From Haryana

- At the same time, unscheduled repair work on the Munak Canal in Haryana has led to a sharp reduction in raw water supply to four other water treatment plants.

- As a result, Haiderpur Phases 1 and 2, Bawana, and Dwarka are currently operating at only 75 per cent of their capacity.

The overall surge in ammonia levels in the Yamuna River and reduced water supply from Haryana have drastically reduced output across Delhi’s water network, leaving the national capital grappling with a severe and prolonged shortage.

When Will Delhi's Water Supply Crisis End?

- Residents in the national capital are likely to experience water supply disruptions till February 4, 2026, as the Munak Canal in Haryana is under maintenance.

- The Delhi Jal Board (DJB) stated that it was informed of the canal closure only on January 19, leaving little time to make alternate arrangements, the report added.

- Authorities have advised residents in affected areas to store water in advance and use it judiciously to avoid inconvenience during the maintenance period.
