Dear editor, I appreciate the fact that the city centre is very clean and well organized. There is only one flaw though. As you move up from ‘Kwarubangura’ stage towards U.T.C around the zebra crossing, there is a strong stench of sewage which makes you feel like suffocating. I think the concerned authorities should take action and deal with the problem. If it’s a leakage in any of the sewage pipes it should be rectified to avoid any further pollution of the air.
