Municipal Corporation Of Delhi — No sewage tank is made for human waste in building

Address:

110030

Dear sir,

i would like to bring your attention towards our locality that a builder is making a building our locality which i think is illegal and m.c.d has also sealed it before but construction work is completed. but my main reason to make complaint now is that m.c.d has not given any sewage pipes in our area and they are not making any septic tank where they can store their human waste.they have directly connected their sewage pipe's to drainage pipes of our locality and they have made nearby 40 flat's in their building.
kindly take some action regarding it or else i have to approach higher.
