1077 is the Helpline for registering complaints regarding water logging.
Delhi Deputy Chief Minister Manish Sisodia on Monday launched a 24x7 helpline - 1077 - to lodge complaints of water-logging in the national capital.
The government called a high level meeting to review water-logging problems after two days of continuous rainfall in Delhi.
"I have directed all agencies to conduct joint inspections at severely affected areas and submit reports by tomorrow (Tuesday)," Mr Sisodia said in a tweet.
In another tweet, he said, "Dial 1077, 24x7 Helpline for registering complaints regarding water logging is functional now. Kindly register your complaint."
He also asked Delhi Police to send separate report on spot for water-logging in Delhi and the cause of it.
Vehicular movement was affected in Delhi due to continuous rainfall for the past two days. The city has been witnessing traffic jams at various intersections due to heavy rains and water-logging it caused.
