How Delhi, Haryana plan to tackle 30% loss of Yamuna water supplied to Capital

Delhi and Haryana are devising strategies to address a 30% loss in the Yamuna water supply reaching the capital city. Currently, Haryana releases 330 cusecs of drinking water daily for Delhi through the Munak Canal, but Delhi only receives 230 cusecs after accounting for a 30% transmission loss. Officials are planning a joint survey to resolve this persistent leakage issue, after three meetings between the Delhi Jal Board and Haryana Irrigation department to repair the Delhi Sub-Branch canal, which is the main channel supplying water to Delhi.

The Water Minister Parvesh Sahib Singh recently reviewed the matter in a meeting on Yamuna rejuvenation. Additionally, it has been proposed that a 1,000-cusec new pipeline be developed, with Haryana's Irrigation department appointing a consultant to prepare a detailed project report. Delhi has agreed to bear its share of the costs for lining the Delhi Sub-Branch canal.

During a meeting with the Delhi Water Minister, the ongoing issues of river pollution and frothing were discussed. A six-point action plan has been formulated to reduce foam in the Yamuna, including redesigning the Okhla barrage, stopping garbage dumping, clearing solid waste, removing floating vegetation like water hyacinth, and ending unauthorized discharges of detergent into drains.

Between December 1, 2025 and July 22, 2026, the Municipal Corporation of Delhi inspected 11,230 units and closed 584 water-polluting units. The Delhi Pollution Control Committee also flagged 188 polluting industrial units in non-conforming areas and shared details with the Municipal Corporation for action.
