Water has begun to return to Delhi residents, where up to 10 million of people were affected after protesters sabotaged a key canal.

The Indian army took control of the Munak canal in neighboring Haryana state on February 22 after Jat community protesters, angry at caste job quotas, seized it.

Delhi Water Minister Kapil Mishra said the “crisis was still not over” and urged people to use water carefully.

The city’s schools, which were closed because of the crisis, have reopened.

Sixteen million people live in the Indian capital Delhi, and around three-fifths of the city’s water is supplied by the Munak canal, which runs through Haryana.

Kapil Mishra tweeted on February 23 that “some water has been released” from the canal. This had led to the restoration of partial supplies in north and central Delhi, he said.

He said more than 70 water tankers from these areas had been moved to the western part of the city, where partial supplies would be “hopefully” restored by Tuesday evening.

“The supply will be limited till the time the Munak [canal] is totally repaired. The crisis is not yet over. People should use water carefully,” he said.

Senior water board official Neeraj Semwal told the AFP news agency that four of Delhi’s nine water treatment plants were operating, forcing rationing of supplies to many areas.

“We are hoping to restore partial services in the next two to three days and 100% supply within the next 15 days,” Neeraj Semwal said.

It is not clear how many households are still without water.

Prior warnings meant that people had managed to save water, and tankers had been dispatched to affected areas of the city, but that this has not been enough to make up for the shortfall.

The army took control of parts of the canal on Monday morning, but repairs are expected to take time. Eighteen people have been killed and hundreds injured in three days of riots.

Protesters went on the rampage despite a curfew and the deployment of the army, which is reported to have opened fire on them, in the districts of Rohtak and Jhajjar.
