Eco-Treatment Zone in Open Drain

Abstract

In India of the 233 class I cities situated in 14 major river basins, only 24% are having proper sewerage systems and class JI cities don 't have any sewerage system for collection of domestic wastewater. Just collection of the sewage is not enough further treatment facility to purify the sewage is also a necessity. So, all these city wastewaters are naturally taken to the nearby rivers and lakes by nallas and odhas (streams - natural drains). These natural drains in the cities are serving as sewerage lines. The studies published by CPCB in 2013 reveal the pathetic condition and inadequacy of pollution treatment infrastructure in India.
