In a written reply, Water Resources Minister Uma Bharati told the Upper House that the project has been sanctioned for the Central Pollution Control Board.
She also stressed at the same time that the National Ganga River Basin Authority has resolved that no untreated municipal sewage or industrial effluent will be discharged into the river by 2020.
The minister said that the locations of the monitoring stations would include upstream and downstream areas of major urban settlements, major tributaries upstream of the confluence of sewerage treatment plants in major drains, downstreams of industrial areas at intakes of drinking water treatment plants and important bathing ghats.
