Water: Indian Scenario

Water Scenario-India
► Indian industries consumed about 50 billion cubic meters of water
► Large population of people lack access to safe water
Water Scarcity-Is a Crisis looming ahead?
► Fresh water available per capita per annum in India has dropped from 5,200 m3 to 1,820 m3 in 01 According to WHO, mortality is high due to water borne diseases
Surface Water-PollutedGround Water-DepletedRainfall - Wasted
Industry -GrowingWater Reqd- Increasing Water Recycle- ? ? ?
Quality of water- PoorHealth Issue- IncreasingIndia’s water future- ???
Population – IncreasingDemand – IncreasingConsumption-Increasing
► Establishment of UMPPs will further strain the thin water resources
Would the next world war would be over
water ?
India is water stressed measured both in terms of quantity and quality
Most of the country receives nearly all its rainfall in less than about 1% of the time of an entire year.
More than 80 percent of river basins are facing stress and scarcity
Groundwater depletion and deterioration
depleting at a rate far greater than what natural cycles can replenish (even > 1 m/ year)
09/10/2013 5
Groundwater quality fast deteriorating
emerging geo-contaminants
non-point source pollutants like nitrates
Less than 1/3rd of our total sewage gets treated
About 50% of riverine length shows high pollution measured in terms of BOD alone
Over 20% of transmissible diseases in India are related to unsafe water

Climatic variability is an add-on stressor.
Regions face growing demand-supply gaps.
Conflicting demands over a shrinking resource

13000 MLD generated by 1,35,000
polluting industries
60% is treated (large & medium
industries)
Domestic
23000 MLD generated (300 Class I Cities and 345 Class II towns)
Only 6000 MLD is treated

Wastewater Recycle & Reuse
Opportunities
2
Recycle & Reuse opportunities
Use of sewage & effluent water for low and high end applications
Use of sewage & effluent water for high end applications
Reuse of treated water as water curtain, floor washings, dual pipe line for toilet flushing etc.
High End Application Cooling Water Make-up
Boiler Feed
Process Water
Low End Application Gardening
Floor Washing
Toilet Flushing

Recycling Initiatives of Indian Industry
Segregates waste streams at source and perform primary/ secondary treatment, locally as appropriate
TDS and Organic Load
Color
Reuse of treated water locally as far as possible
Cost Effective
Reduce of fresh water intake
Installed common tertiary treatment plant for further treatment and reuse

Case Study-I
Conservation of Ground Water
Reuse of 220m3/day of Secondary Treated Wastewater
Installed full fledged tertiary
treated water system using
submerged UF-RO membrane
Utilized for non-potable
purposes
Fresh water savings of 73000m3/year
