Water: Indian Scenario

26/03/2014 4

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-Polluted Ground Water-Depleted Rainfall - Wasted Industry -Growing Water Reqd- Increasing Water Recycle- ? ? ? Quality of water- Poor Health Issue- Increasing India’s water future- ??? Population – Increasing Demand – Increasing Consumption-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

Water stress line (1700) Water scarcity line (1000)

Per capita water availability (m3/capita)

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

Wastewater Treatment : Present Scenario

• Industrial

 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

Looking for alternative sources

Well Water Surface Water Municipal Water Internal WW Reuse RO Reject RO Permeate Boiler Blow Down ZLD Distillate MBR Effluent Additional Treatment?

Treated Water

Municipal Treated WW Can use many sources of lower quality water * * With proper system design and treatment

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

Full range of technologies for primary, secondary and advanced wastewter treatment & reuse

Success Stories3

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

26/03/2014 17

Zero Water Discharge

• Effluent Generation of ~

800m3/day

 Process

• Component Washing
• Paint Booth

 Utilities

• Cooling Tower
• Filter Backwash

 Sewage

• Percentage of Treated

Effluent in Daily Consumption

 35% in Process  Rest Green Belt Development

CII-TWI and USAID India partnership

• Objective

To Promote Water Use Efficiency across Urban Sector to Address Climate Change

• Activities undertaken

 Water audits in Industry, buildings /hospitals  Pre-feasibility studies for utilizing municipal sewage  Identification of doable projects on reuse of sewage  Information Dissemination and Capacity Building Programs
