Sir: Pollution and sewerage problems have not even spared the Karachi University where filthy water supply system continues to go unchecked by the administration. Apart from the university’s algae-infested water tank, which has not yet been cleaned, deteriorating water pipes speak volumes about the official callousness. This contaminated water has put the health of at least 30,000 enrolled students and 700 university teachers at risk. Rust-covered pipes and sewage water mixing with drinkable water are a gruesome sight. A lecturer recently told media sources, “It is the lethargic act of varsity’s administration and there is no serious attention paid towards this alarming issue. We are compelled to drink this filthy water, as we cannot buy mineral water for our daily use.” Although filters have been installed at some of the departments, but still, teachers prefer not to drink water from it and bring boiled water from their homes. Whereas, most of the students continue to use this filthy water to quench their thirst. We request the university’s registrar to take serious measures to resolve this outstanding issue by focusing on its improper and filthy water supply. Prior to diverting his attention towards other areas of the city. Although numerous promises have been made in the recent years, none had yet been fulfilled. Appropriate practical steps are needed to solve this problem. M. ZUBAIR KHAN Karachi
