Insights Hub: Water Metric Definitions

This metric can be used to understand the share of recycled water that facilities are using and identify opportunities to increase the use of recycled water, reducing the use of water from withdrawn sources.

(sum(watsourcecond, watsourcemunicipalgrey, watsourcerecycle, watsourcereuse, watsourcewaste, watsourcewasteinternal)/ sum(total_water_l))*100

• Take the total liters of water from all recycled sources and divide it by the total liters of water usage. Multiply that value by 100 to get the percentage.

This metric can be used to understand the share of withdrawn water that facilities use and identify opportunities for improvement and conservation efforts.

${watsourcewithdrawal} / NULLIF(${watsourcetotaltotal}, 0) * 100

• Divide the total water source withdrawals by the sum of total water source values, but only if the water use isn’t zero. Multiply that value by 100 to get the percentage. 

This metric can be used to track and report the quantity of blue water consumption, inform blue water reduction targets or give insight into water.

sum(watsourcesurfacetotal, watsourcegroundtotal, watsourcemunicipalbluetotal, watsourcemunicipalunktotal, watsourceseatotal, watsourcecondtotal, watsourceraintotal)

• Add up the total liters of water usage from:
  • Surface water
  • Groundwater
  • Municipal blue water
  • Municipal water of unknown origin
  • Brackish surface/seawater
  • Condensate from external steam source usage
  • Rainwater

This metric can be used to track and report the quantity of grey water consumption, inform targets or track uptake of grey water in place of blue water.

sum(watsourcemunicipalgreytotal, watsourcerecycletotal, watsourcereusetotal, watsourcewastetotal, watsourcewasteinternaltotal)

• Add up the total liters of water usage from:
  • Municipal grey water
  • Recycled water
  • Reused water
  • Treated wastewater
  • Untreated wastewater that is internally treated 

This metric can be used to contextualize facility water use on a per product basis.

sum(finalProductAssembly_water_l) / sum(annual_prod_vol_finalProductAssembly_amount)

• Take the total liters of water withdrawal from a finished product assembler and divide it by the finished product assembler’s annual production volume quantity.

This metric can be used to contextualize facility water use per kilogram of production.

sum(printingProductDyeingAndLaundering_water_l,
hardComponentTrimProduction_water_l,
materialProduction_water_l,
rawMaterialProcessing_water_l,
rawMaterialCollection_water_l) / sum(annual_prod_vol_printingProductDyeingAndLaundering_amount, annual_prod_vol_hardComponentTrimProduction_amount, annual_prod_vol_materialProduction_amount,
annual_prod_vol_rawMaterialProcessing_amount,
annual_prod_vol_rawMaterialCollection_amount)

• Divide the sum total liters of water withdrawal from the list of facility types by the sum total of annual production volume quantity from the list of facility types:
  • Finished Product Processing (Product Printing, Product Painting, Product Dyeing, Product Laundering and Product Finishing, Embroidery & Embellishments)
  • Component / Sub-Assembly Manufacturing (incl Packaging)
  • Material Production (Raw and intermediate materials are transformed into their final state before assembly)
  • Raw Material Processing (Raw Materials are processed into intermediate material products) (e.g. Yarn Spinning)
  • Raw Material Collection & Bulk Refining (Materials are collected/extracted/farmed and refined to bulk commodity state)

This can be used as an initial evaluation of water use performance in facilities. Strategic decisions should include other metrics as the water score alone may not provide regional or site specific insight necessary to effectively reduce water use impacts.

average(total_water_score)

• The average of all water section scores.
