An unprecedented water crisis looms large over the city with neighbouring Haryana drastically cutting supply on Thursday, leaving various treatment plants short of raw water and areas across the city parched. Areas across the city have already been grappling with acute shortage of water and the situation may worsen further as production at water treatment plants has come down sharply due to shortage of raw water. Top officials in the Delhi government said that most areas in the city will face severe water shortage and accused the neighbouring state of playing “foul” with Delhi on the water issue. “The people of Delhi are bound to face acute shortage of drinking water as Haryana has arbitrarily and drastically curtailed raw water supply,” said a late night statement from the chief minister’s office. Considering the gravity of the situation, chief minister Sheila Dikshit has been trying to speak to her Haryana counterpart Bhupinder Singh Hooda but to no avail, sources said. Expressing anger at Haryana cutting raw water, chief minister’s office said the Delhi government would take up the issue “at all levels” as Delhi is not just a city but the national capital. “We are not asking for any favour. We want what is due to us,” it said. The production of water in various treatment plants has come down by 45 million gallon per day (MGD) which would leave most people “thirsty” on Friday. “The residents of north, west, New Delhi and Walled City face a difficult situation Around 25 lakh residents in Khayala, Patel Nagar, Moti Nagar, Kirti Nagar, Narela, Bawana Wazirabad, and Old Delhi will be affected,” it said. The production of water at Wazirabad treatment plant is down by 30 MGD while Haiderpur plant produced 15 MGD water less.
