Delhi Jal Board — sewage mixed water supply in houses

Address:

Old Rajinder Nagar

Sir,
I am a resident of old rajinder nagar and we are getting foul smelling sewage mix water supply at homes from past two days i. E from 18 july 2019 till present. The lives of the residents are disturbed due to this. How can one use this kind of water? I mean it will make people ill. Already there are many problems related to water but whole old rajinder nagar is recieving the same foul smelling water.
Do something or people will get trapped into water borne diseases.
Please take urgent action as it is getting unbearable.

Thanks
