Address: New Delhi, Delhi

I am living in B-15/B, Nishat Park, Kakrola Mor, New Delhi-78. There is a new construction in front of my house. some persons are living there. They flow waste water in drain while drain is blocked from both end. The drain is open also. So, waste water is stored in drain. Due to that, mosquito population is raising day by day. Please help us.
