Address: 521,1stmain, shubodaya layout, Marathalli, Bangalore, 560037

Dear sir,
I want to bring to your notice, in marathalli 1st main sewage is blocked from a week. Inspite of giving written complaint, officials have not bothered to clear it.
Water is flowing back in many resident houses. It is affecting the health and hygiene of people.
It's been a week issue is not solved.
Bwssb officials have shown deaf ears to our problem.
Kindly intervene and get the work done.
