A coin-operated water purifying plant was inaugurated by Hyderabad MP Asaduddin Owaisi and Mayor Mohd. Majid Hussain at Syed Nagar 2 in First Lancer on Sunday. The plant consists of two tanks of 3,000 litres capacity each and can be operated by inserting a one rupee coin. A person can avail up to 11 litres of purified water for one rupee. The facility will benefit a few hundred families in the area. In November, a similar project was launched at Mahboob Colony in Asif Nagar.
