Kumari Builders & Developers — Drainage problem in kumari brundavan

Address:

Kumari brundavan apartments

During construction of this project a pit was created on back side of the building for drainage of washroom/kitchen water.
Now someone who claims to have acquired the land has demolished the pit and blocked our drainage.

This is causing all the water from septic tank inside our apartment to overflow in society basement.
Complete basement is inhabitable and smelling.
We have kids living in our society. Please take urgent action on this.
