Nullahs and streams flowing through Islamabad have become dumping stations owing to negligence on the part of CDA. The city is begging to stink thanks to its streams and nullas that have become garbage dumping stations owing to negligence on part of the CDA. Slum dwellers and residents of nearby localities started throwing waste into them. Again as there were no checks by CDA. People began to extend their private drains to these drainages discharging domestic waste into them. Slum dwellers living along these drainages not only have to bear the reek of dumped waste all day but they are also at the risk of becoming affected with dangerous disease, since these drainages are breeding grounds for various life threatening virus and bacteria.
