"We've completely run out of water. I appeal to the Centre with folded hands to immediately intervene and get Munak canal started in Haryana," Kejriwal said in a tweet.
The Munak canal in Haryana, which supplies water to many parts of Delhi, was shut down after it was vandalised by a section of Jats demanding quota in government jobs and educational institutions.
Meanwhile, Delhi Deputy Chief Minister Manish Sisodia said there was no water supply to his residence on Monday.
"So! dry day starts from today (Monday)? No water supply at my home this morning. No hope to get water in Munak canal. Tough days ahead for Delhi," Sisodia said in a tweet.
Earlier on Sunday, Delhi Water Minister Kapil Mishra termed the water crisis in the national capital "unprecedented", and warned warned that the situation might worsen in the next few days if the supply from Haryana was not immediately restored.
He informed that the Delhi Jal Board (DJB) had almost run out of water and advised people to use water judiciously.
Delhi has nine water treatment plants which together produce 820 million gallons per day (MGD) of potable water. Of these, only two - Sonia Vihar and Bhagirathi - fed by water from Uttar Pradesh are operational. The current production is only 240 MGD. Delhi gets its bulk of water supply from Haryana.(IANS)
