The water footprint
The water footprint shows how much water is used for consumption by people. The water footprint of an individual, community or business is defined as the total volume of freshwater used to produce goods and services consumed by the individual or community or produced by the company. Water use is measured by the volume of water consumed and / or contaminated per unit time.
Tool for Mine
Water Footprint
1.
Historical focus:
Mine water management usually work practically at mining
sites to meet the needs of water for mining. It focuses on the disposal of
extra water and other issues about mine water.
2. Mine
water stockpile:
While discussing the mine water issues there must be a
stockpile for mine water. From this we know about the inputs, outputs, storage
and diversions of water at mining site.
3. Unfair
able conditions:
Stockpile gives very easy to understand the water management
but there are some unfavorable conditions that make the development of mine
water inventory inconvenient. Such as climate change; not gave proper blue prints
of water flow and changing in project.
4.
Evaluation of mine water balance:
The stock book gives the complete information about the
physical system; water inputs and outputs; evaporation and flows of mine water.
It also establishes rules for future management of mine water. In the development of mine water balance the
inventory give all the possible factors and uncertainties while making mining
projects.
5.
Rectifications:
While using water balance and inventory methodology we can
identify leaks, open loop and other factors affecting performance at mining
sites. These factors can be improved by using 3R strategies; change mining
planes and collect the correct flows of water.
6. Co-operate
Reporting schemes:
Different companies as like CDP Water, MCA Water Accounting
Framework and Lifecycle Assessments gave the whole Statistics of water use at
mining sites.
7. Water
Accounting:
It gives the detailed data from water balance and gave
results that used at large scale for mining operations.
8. Regional
Impacts:
Hydraulic, geochemical and hydrogeological studies used to
recognize the source of water and understand the impacts of region. From this
step we can compare the quality of mine water.
9. Positive
Effects of Mining:
Enhance the development of mining at large scale with low
consumptions. Social media also plays huge role to encourage NGO’s for the sake
of environment and community issues. By this effect people know about the
importance of water.
10. Water Footprint:
All the above factors come to the water foot print the
important role in water impact assessment. The impacts of water foot prints
measures fresh water devote, spatial and temporal dimensions fully
supply-chain. It helps to focus on less use of water footprint.
11.
Methods:
ISO method gives the process to develop water footprint. Water
footprint network categories into green, blue and grey water. Green water comes
from soil or by vegetation and use to make products. Than the unused water goes
to ground surface this water calls the blue water and transfer to different
catchments. The third category i.e. Grey water is dilute discharge to full fill
the goals of mining.
12. Index:
CUI consumptive water use Index gives the information about
the availability and confirm the level of water in store. DUI degradative water
use Index informed about the quality of mine water. Single Indicator water
footprint gives solutions to adjust the footprint according to CUI, DUI, site
inspections and most importance activeness of stake holders.
13.
Affecting Factors:
There are many factors that affect the water foot print such
as climate change, site conditions, and water resources management techniques,
quality of water, locality and discharge methods.
14. Water
Stress Index:
Water footprint can be more useful by comparing areas of
water where it is plenty or surplus. As water depletion index, available water
remaining (WULCA), blue water scarcity. Water stress index also remarked the
presence of metals’ in mines. Although the regional WSI provides the more
suitable water footprints.
15. Actions
to Take:
Being Socialized
Good relations and
Communication Skills
Give the proper plan of water use
Take the actions to cover the problems related to climate
change
Use 3R strategy
