Delhi Jal Board — Sewer blockage and overflow for 2 months

Address:

New Delhi, Delhi, 110089

1 sewer of my locality is blocked for 2 months and overflowed. Water comes outside and stay in drains. It smells very badly and causes diseases to localities. I complaint many times but no action taken yet. Now monsoon also arrives due to which the sewer water that stay in drains comes on roads. I also complained online two times and to the department 3-4 times but all in vain. So look into this matter as we are tax payers and this problem is serious now.
My locality address is g-6-59, 63 sector-16, rohini, delhi-110089
