The trench, which was dug up to lay pipeline for 24×7 supply of water about 15 days ago on C.V. Road near Noor Masjid, is not covered resulting in sewage water getting collected in the trench resulting in mosquitoes breeding in the stagnant sewage water. Also, foul smell is emanating from the stagnant water causing inconvenience to all. Authorities concerned are urged to get the trench covered soon.
