Overview
- Delhi Jal Board said the Wazirabad plant was fully shut and Chandrawal cut back, with Haiderpur, Bawana, Dwarka and Nangloi also operating below capacity.
- Advisories warned of low pressure and intermittent supply in wide areas, with potential disruptions extending to February 4 despite efforts to stabilise operations.
- Ammonia in Yamuna raw water topped 3 ppm, exceeding plants’ design limit near 1 ppm and rendering standard chlorination unsafe for full-scale treatment.
- Haryana’s irrigation department had notified a canal closure from January 19 to February 4, but maintenance was suspended on Friday to restore regular flow and aid dilution, with officials indicating possible normalisation by January 24.
- DJB is rationing supply, deploying tankers and rerouting where possible as residents report dry taps and foul odours, while Delhi and Haryana trade blame over pollution sources.
