Municipal Corporation Of Delhi — drain block

I am a resident of the dda janta flat, ladosarai, gate no-4. My complaint is regarding the drainage system during rainy season in front of the houses 481-542. The dirty water from the drainage often overflow into the pathway and is very difficult for us to pass though the students during school hours and for us during office hours. The water accumulating in front of our gali take minimum 4-5 hours to get rid off after rain. The water is entering to the electricity meter box and to our houses during rain its already informed to the area mcd councillor and visited the site last year., but no action has been taken till now.
I request the authorities to take necessary action regarding this matter which is causing considerable inconvenience to us
