Delhi Development Authority [DDA] — Pipe line

Address: Flat No. 1144 Ground Floor, Block No. GH1, PKT -1, Rohini Sec -29

My residence address is Flat No. 1144 Ground Floor, Block No. GH1, PKT -1, Rohini Sec -29 Delhi. One pipeline to drain the water from the roof is leaked for a long time and the water is always poured into my flat. It is used for entire building to drain the water from the roof not for any individual flat. So that it is responsibility of DDA/RWA to fix it. It is my humble request to take necessary action as soon as possible.
