Disposal of waste water in Ganga basin

Industrial & Domestic Waste discharge in River Ganga

 

  • Both industrial effluent and domestic waste water contribute to the pollution in river Ganga. 6614 MLD of waste water with an organic pollution load of 426 TPD is discharged into river Ganga.
  • Approximately 90% of the river’s natural discharge is extracted by the time the river reaches Kanpur.
  • 764 Grossly Polluting Industries (GPIs) are directly discharging their effluent into river Ganga.
  • 90% of GPIs are located in Uttar Pradesh while 58% of the GPIs constitute of tannery sector.
  • Pulp and Paper sector contributes highest quantity of BOD load (65%) and effluent discharge ( 55%), whereas the maximum average BOD is discharged by the distillery sector
  • The drains in Uttar Pradesh contribute 57% of wastewater flow and 44% of the BOD load to river Ganga.
  • Domestic waste water percentage contribution in the total quantity of wastewater and BOD load is 92 and 69 respectively and the remaining is contributed by industrial effluent
  • Maximum wastewater discharge & BOD load have been reported from segment III B and IV A respectively.Segment III A& B and Segment IV A have very water poor quality w.r.t BOD & FC concentration levels. River Ganga receives 80% of the total organic load in these segments. The concentration of Pulp & Paper, Distillery & Tannery units is maximum in these segments. Poor water quality in these segments can be directly attributed to the organic load contributed by the domestic & industrial discharges.
