Delhi Development Authority [DDA] — sewer failure and garbage littering

Address: New Delhi, Delhi

Hello,
I am a resident of dda kalyan vihar. Sewer system here is in complete failed status. Garbage is littering everywhere on top of sewer overflow. No idea what dda employees posted here are doing. They just around idle. This has been condition from past few years. Living has become hell for children's and everyone. Adding photo for same. It's really in unhygienic condition.

Please help on long term fix.

Thanks
