Rajpur Sonarpur Municipality — Unauthorised /personaly/3 inch drain pipe has been installed without permission

I sanjib kr.sengupta, retired pensioner residing at policepara panchpota dhalua 39D-khudiram sarani under rajpur sonarpur municipality ward No 3 of kol 152, writing to express my serious concern regarding an issue that has been arisen within my property . It has come to my attention that due to my absence, an unauthorised 3 inch drain pipe has been installed from his house to just by outside of my boundary wall east which is part of the common passage. And this has been done when I was not in house. This drain pipe is releasing dirty water, stop there where there is no outlet drain causing both visual & hygienic problem. My bed room is attached to this boundry wall. This situations not only impacts the aesthetics of my property but also raises health concerns due to the unsanitary nature of the bathroom & boundry water being discharged. I have been suffering diabetic migrain & hearth problem for last 25 years. I therefore request your goodself to kindly look into the matter & solve the problem as early as possible. Thanking you. I am enclosing drain side boundry wall.
