Uncovered sewerage line

This refers to the problem concerning the main sewerage line that has been left uncovered in North Nazimabad (passing through the Sakhi Hassan roundabout from Qalandarya Chowk to Peoples' Chowrangi).
The eucalyptus trees growing adjacent to the road should also be cut down as they block the street lights. It is beyond one's understanding why the authorities have left the work incomplete, even when they have cut down the trees and covered most of the portion.
The reason why this sewerage line must be covered is that the boundary wall of this sewerage line is broken in places, posing a danger. There is a chance for vehicles to fall in. Also the nearby residents throw garbage in it, which causes overflow of drain water, especially in the monsoon season. Therefore, I urge the authorities to cover this sewerage line as soon as possible.
