Nalas /drain of Karachi - Besides desilting the issues in flowPiling - negligent dumping of earth at the openings
Korangi Road. Manzoor colony nala crosses here, then
passes thru DHA reclaimed land (near Qayyumabad),and falls into the sea. Takes water from 70% Jamshed
Town also from Nursery & Airport road. Piling
for road construction, blocks the culvert openings
restricting flow.

joins Nehr-e-Khyam. These 2 pipes, 36” dia shown in photos above, mostly filled up with debris arethe connections of the branch drain to Nehr-e-Khyam.
