RAWALPINDI – Nullah Leh flowing through Rawalpindi has become a dumping station due to negligence of the Wasa. Slum dwellers and residents of the nearby localities started throwing waste into the nullah, as there is no check by the concerned authorities. People began to extend their private drains to the nullah by 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.
