Water Usage per Unit with total water withdrawn of 950,000 gal: a worked example

Push total water withdrawn up to 950,000 gal and the picture changes. This example computes every intermediate figure at that operating point. a sustainability or facilities manager needs water intensity for a product, line, or reporting period

The inputs for this scenario

  • Total water withdrawn (metered): 950,000 gal (raised for this scenario; the documented default is 380,000)
  • Sellable units produced: 95,000 units (unchanged)
  • Reporting unit conversion factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Raw water intensity = total water use รท production volume) to the inputs above produces each figure below.
  • At this operating point the engine returns 10 gal / unit for reported water usage per unit, the number this scenario is built around.
  • At this operating point the engine returns 10 gal / unit for raw water intensity.
  • At this operating point the engine returns 1 x for unit conversion factor.
  • At this operating point the engine returns 95,000 units for production volume.

How this compares with the baseline

  • Against the tool's baseline example, where total water withdrawn sits at 380,000 gal and the headline result is 4 gal / unit, this scenario comes in 150% above the baseline at 10 gal / unit.
  • It divides total metered water withdrawal by sellable production volume, then applies a reporting conversion factor, to give gallons of water consumed per unit produced. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Reported water usage per unit: 10 gal / unit (headline result)
  • Raw water intensity: 10 gal / unit
  • Unit conversion factor: 1 x
  • Production volume: 95,000 units
