Najafgarh Drain in western Delhi is one of the most polluted water bodies in the world. The scenes on along this drain and its banks are invariably dramatic. The long wall along most of its eastern bank is broken without repair at most places and garbage heaps pile there. The drain side of the wall at the broken parts are tainted with urine stains. And invariably, through the broken walls could be seen the tips of cranes at work near the edges of the drain. Birds of prey would keep soaring above the river looking for a chance prey, as the one seen in this photograph.
