NEW DELHI (AFP) - A water crisis in India's capital will take up to two weeks to fix, authorities warned on Tuesday, as taps ran dry, days after protesters sabotaged a crucial waterway to press a demand for better treatment for their caste.
The Jat caste called off their protests on Monday after the government in the northern state of Haryana accepted their demands following days of riots, arson and looting that saw thousands of troops deployed.
But New Delhi's water board was still racing to restore full supplies to the city of 17 million people that relies heavily on a canal running through Haryana, which encircles the city on all but its east side.
Water trucks fanned out across the teeming, landlocked city, where infrastructure struggles at the best of times, but it was not clear just how many people were still affected, although many households were without regular water four days after the canal was badly damaged.
Senior water board official Neeraj Semwal said just four of the city'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 per cent supply within next 15 days," Semwal told AFP.
"North, west and south Delhi districts were severely affected by the water shortage with thousands of households not getting regular water supplies."
Delhi water minister Kapil Mishra tweeted that the crisis was "not over yet" and urged residents to conserve water.
India sent troops to secure the canal after protesters demanding a quota for their Jat caste in public service jobs and higher education seized it on Saturday and diverted the water flow away from the capital.
Although schools and many businesses reopened on Tuesday as supplies were partially restored, many were still suffering after the water board said it had been forced to limit supplies.
Retired journalist K. Jagannadha Rao said he and his neighbours scrambled to fill as many buckets and drums as they could carry after waiting 24 hours for a tanker to arrive.
"We have been having a lot of problems with the piped supply for the last three days. There are 110 flats in our complex and everyone has been facing problems," the 73-year-old told AFP.
"We never imagined we would have to face such problems."
About 400 million gallons were being produced after the attack compared to the usual 820 million gallons a day, according to local media, although Semwal said he could not confirm this.
Many neighbourhoods have supplies piped to their homes, while others still rely solely on tankers to deliver water for cooking and washing.
The crisis has underscored the vulnerability of the Indian capital, which receives little rain and has long struggled to provide enough water for its rapidly growing population.
Thousands of troops had been deployed to Haryana on Saturday with orders to shoot on sight after week-long protests by members of the caste turned violent, with rioters setting fire to homes and railway stations and blocking highways.
Haryana additional chief secretary P K Das said no clashes were reported overnight and curfews have now been lifted in most areas.
The protests eased on Sunday after Haryana's government agreed to the Jats' demand for preferential access to sought-after government jobs and university places under India's caste-based quota system.
