Chief Minister Arvind Kejriwal on Friday wrote to Prime Minister Narendra Modi asking him to intervene to prevent a water crisis in Delhi. On Thursday, Kejriwal had written to his Haryana counterpart Manohar Lal Khattar, asking him to not reduce the amount of water his state supplied to Delhi, otherwise the national Capital would face an “unprecedented” water scarcity.

The Delhi chief minister said Haryana should not disrupt the supply until the Supreme Court has made a decision on the matter. “I would urge you [Modi] to kindly use your good offices to persuade Haryana to continue supplying same level of water that it has been supplying for last 22 years and not to disrupt it till the issue is finally decided by the courts,” Kejriwal wrote.

Kejriwal had also written to Delhi Lieutenant Governor Anil Baijal, asking him to persuade Haryana to maintain the current supply levels. His letters came after the Haryana government told the Supreme Court on Wednesday that it would maintain the current water supply from the Yamuna river to Delhi till May 21. Kejriwal told Baijal that if Haryana reduced the water supply after May 21, Delhi could experience a water shortage.
