Municipal Corporation Of Chennai — drainage block in our street

Address:

Chennai, Tamil Nadu, 600100

Hi,
There is drainage block happening whenever it's raining. Due to this drainage water level increases and slowly coming inside our home through drainage pipe. My father tried clearing the drainage blocks and there is a hole in which his right leg went inside. It's duty of municipality team who haven't cleared the blocks even we reported the incident already.

I believe, necessary steps will be taken by the respective team.
Due to carelessness of few people and occupied public pavements, other people like us getting problems.
