Sir: Being an habitant of Malir, I wish to highlight the issue choked sewerage line in Malir. Despite having many complaints, stagnant sewerage water is never removed and many manholes are open and many incidents of falling children are reported. Moreover, due to the obnoxious smell all around, residents are suffering from different kinds of diseases. I request concern authorities to look into the matter and save people from viral diseases.
