2. World: 2.7% freshwater
13 million km3 sustains life but erratically
distributed
India: 4% of worlds water
 Freshwater/ person: 1,486 m3
600 million faces high to extreme water
stress
6% loss in the country’s Gross Domestic
Product (GDP) by 2050 (NITI AYOG, 2020)
Water scarcity
 4 billion people
faces severe water
shortage/month/ye
ar
 2 billion people
lives in water scare
country
 700 million people
could migrate by
water scarcity
 Out of 4 children 1
could face extreme
scarcity in the
globe by 2040
(UNICEF, 2020)
Water footprint
World:1240 m3/person/year
 USA highest (2483)
India: 980
Great scope: to implement in water scare
regions
Target was to maximize
water use by altering the
consumption pattern to
enhance WUE
 An efficient tool to improve the
management and sustainability of
water resources
 Denotes the volume of fresh water
used, consumed and/or polluted
 Assesses the eco-friendly nature of
product

3. Methodology
 Business Water Footprint (WF)
accounting procedure was used to
evaluate the Water Footprint of the
college.
 Operational (or direct) WF:
Volume of freshwater consumed or
polluted due to the business’s own
 Supply chain (or indirect) WF:
Volume of freshwater consumed or
polluted to manufacture all the
goods and services that form the
inputs of production of the business
 WF bus = WF bus, oper + WF bus, sup
 WF bus, oper = WFoper, green + WFoper, blue + WFoper, grey

7. Conclusions
Water Footprint can be reduced by shifting the consumption
pattern
that needs minimum water
Gray water’ can be utilized for landscaping and the rest can be
utilized for toilet flushing, waste plate washing
Minimization of costs in production and enhancement of
resource efficiency
Water footprint aids in hazard identification and creation of
mitigation approaches
Water footprint optimizes and restricts allied environmental
impacts
Thus, to reduce, overall Water Footprint it is indorsed to limits
the water import by maximizes the utilization of the Campus
water potential; by shifting to the consumption pattern of
material use/foods, which requires less water; and by increasing
the water use efficiency by reducing the wastage, reuse and
recycling the waste water
