Wastewater Cost per Unit with allocated wastewater cost of 46,000 $: a worked example

Push allocated wastewater cost up to 46,000 $ and the picture changes. This example computes every intermediate figure at that operating point. an EHS or finance lead needs wastewater cost per unit of production

The inputs for this scenario

  • Allocated wastewater cost: 46,000 $ (raised for this scenario; the documented default is 18,400)
  • Production volume: 92,000 units (unchanged)
  • Allocation or conversion factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Raw wastewater cost intensity = allocated wastewater cost รท production volume) to the inputs above produces each figure below.
  • At this operating point the engine returns 0.5 $ / unit for wastewater cost per unit, the number this scenario is built around.
  • At this operating point the engine returns 0.5 $ / unit for raw wastewater cost intensity.
  • At this operating point the engine returns 1 x for allocation or conversion factor.
  • At this operating point the engine returns 92,000 units for production volume.

How this compares with the baseline

  • Against the tool's baseline example, where allocated wastewater cost sits at 18,400 $ and the headline result is 0.2 $ / unit, this scenario comes in 150% above the baseline at 0.5 $ / unit.
  • It allocates a wastewater cost pool across production volume to give a raw cost intensity, then applies an allocation or conversion factor to express it per finished unit. 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

  • Wastewater cost per unit: 0.5 $ / unit (headline result)
  • Raw wastewater cost intensity: 0.5 $ / unit
  • Allocation or conversion factor: 1 x
  • Production volume: 92,000 units
