Delhi Chief Minister Arvind Kejriwal visited Wazirabad water treatment plant today after it was shut down due to the rise in the water level of the Yamuna river. "We are at the Wazirabad water treatment plant. For the first time in Delhi, Yamuna has touched this level. Three water treatment plants have been shut down due to this as the water has entered pumps and machines. 25 per cent of the water supply in Delhi will go down due to this. The tubewells are closed too," Mr Kejriwal said. He said there could be water scarcity for a day or two. "I hope supply resumes by tomorrow evening," he added.
