Revitalization of Rivers In India
Draft Policy Recommendation

INTACH’s Bacterial Bio-remediation
A bacterial bioremediation process, applied on a polluted flowing
river itself, using a combination of dosing of anaerobic bacteria and
floating and submerged media has been piloted by Indian National
Trust for Art & Cultural Heritage (INTACH) on a stretch of the Assi
River near Varanasi.
The results show about 80% reduction in BOD and 50% reduction in
COD a month after initiation of the intervention. . (Manu Bhatnagar,
INTACH, 2017)
The Case Study section at the end of this chapter provides additional
information about this initiative.
Based on the information available, the following may be surmised:
»»
It is a low-cost intervention that can be immediately
applied in its present form in any feasible polluted
stretch of rivulets / streams across India.
»»
While the river water quality has not reached the
aspired water quality, the reduction is very significant
and warrants its use, particularly as a short-term and
medium-term intervention.
»»
The system in its present form may find immediate
application only on river stretches that are not too wide.
Modifications for application on wider stretches may
need to be worked upon.
»»
This is an immediate solution for reduction in pollution
in river stretches where there are no existing STP
facilities resulting in direct disposal of sewage into the
river.
