2.2.1 New pattern of diverting wastewater to a pool forming wetland
Lockdown for over three months from March to May 2020 for containing contagious pandemic COVID -19, which stopped any waste water inflow in rivers Ganga and Yamuna, led to self cleansing of bad quality water in to very clean water. This became a lesson that in the river systems no waste water, be it domestic or industrial, be dumped in rivers, irrespective of whatever quality. It means all waste water coming as sewage water should be led to any lowland in downstream direction and makes a wetland pool. How to manage the wetland was dealt with by studies (Yadav 2020a,b). The physical feature of the pattern of waste water diversion in downstream sides both left and right sides of the rivers is depicted vide Fig 2. Although wetlands must have existed in the past, but such wisdom of maintaining clean water had not existed. The innovative measure will become first insight leading to foolproof measure for cleaning of river water without undue budget and wastage of time and efforts. Such details will be taken up in result part of study.
