It asked the Upper Yamuna River Board (UYRB) to measure water released by Himachal Pradesh at Hathnikund in Haryana. Haryana should not obstruct the onward flow of water to Delhi from Himachal but should instead facilitate the same, the bench said.

The apex court said, "Considering the urgency, we direct Himachal Pradesh to release 137 cusecs water from upstream so water reaches Hathnikund barrage and reaches Delhi through Wazirabad. The surplus water shall be released by the State of Himachal Pradesh tomorrow with prior intimation. The State of Haryana shall facilitate the flow of water from Hathnikund to Wazirabad so it reaches Delhi without obstruction so the residents get drinking water." The bench sought a status report in this regard by Monday.

Amid the water shortage in the national capital, the Delhi government had approached the Supreme Court to get immediate additional water from neighbouring Haryana.

Delhi government in its plea said that it is constrained to file the petition on account of the acute shortage of water being faced by the people of of Delhi, triggered by the ongoing severe heat conditions in North India, particularly in Delhi.

"Direct the Respondent no. 1 (Haryana) for immediate and continuous release of water at the Wazirabad barrage," the plea has stated.

The record-high temperatures and heatwave in Delhi, which has resulted in maximum temperature rising up to around 50 degrees Celsius at some places, have caused an extraordinary and excessive surge in water demand in the city, it said.

As a result, the national capital is dealing with a water shortage which has led to frequent supply cuts in many parts of the NCT of Delhi, and has disrupted the daily life of the ordinary residents, added the plea.
