Delhi Jal Board — smelly water supply

Address:

New Delhi, Delhi

The water supply in my locality is super smelly and bad from past few days. Kindly see to it. It's not possible to use that water. Water condition is so bad that even after ro filteration water is not usable. It's too contaminated that our children get diseases from it. It's not done. We pay taxes and what we get in return is non drinkable water. This happens every 2-3 months water. Kindly help. We can't take this.
