===Urban flooding in monsoon season===
Size of Drainage system and storm water drains (locally known as Naalahs) in the city is not enough to handle the heavy rainfalls of monsoon. The drainage system and storm water drains are also filled with solid trash. When water finds no path, it enters streets, roads, underpasses and even houses during rainfall in July and August of every year. Major Naalahs like Orangi Naalah, Gujjar Naalah, Mehmoodabad Naalah are cleaned every year by government but are polluted by people the next day.<ref>{{Cite web |last=Ilyas |first=Faiza |date=8 July 2018 |title=Encroached drains, poor waste management put Karachi at risk of urban flooding |url=https://www.dawn.com/news/1418576 |access-date=28 November 2023 |website=DAWN.COM |archive-date=8 July 2018 |archive-url=https://web.archive.org/web/20180708062341/https://www.dawn.com/news/1418576 |url-status=live }}</ref>
