Plant Water Use per Unit with total plant water use of 62,500 gal: a worked example

This worked example runs the plant water use per unit numbers for a tougher week than the baseline: total plant water use of 62,500 gal instead of the typical 125,000 gal. Calculate plant water use per good unit from total gallons and production count.

The inputs for this scenario

  • Total plant water use: 62,500 gal (the input this scenario stresses; the baseline uses 125,000)
  • Good production units: 50,000 units (held at the documented default)
  • Unit conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Water use per unit = total plant water use ÷ good production units × unit conversion factor.
  • Water use per good unit works out to 1.25 gal / unit at these inputs, and this is the headline figure for the scenario.
  • Raw ratio works out to 1.25 value at these inputs.
  • Unit conversion factor works out to 1 x at these inputs.
  • Good production units works out to 50,000 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where total plant water use sits at 125,000 gal and the headline result is 2.5 gal / unit, this scenario comes in 50% below the baseline at 1.25 gal / unit.
  • Use it for monthly or per-line water KPI tracking, sustainability reporting, and comparing water intensity across periods or plants. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Water use per good unit: 1.25 gal / unit (headline result)
  • Raw ratio: 1.25 value
  • Unit conversion factor: 1 x
  • Good production units: 50,000 value
