Delhi Jal Board — sewage overflow along with a school

Address:

New Delhi, Delhi, 110014

I am complaining on the behalf of shikshalaya: a real learning place, jangpura b. We are facing this problem from more than 2 weeks now.
All water used in school goes to the sewage, which is outside the school but all water is coming out on road and a lot of mosquitoes are laying eggs there.
It's very unhygienic for kids.
School address is 10 mathura road, jangpura b, near rajdoot hotel.
