The challenge

A promising green business idea with no numbers behind it.

What I did

  • Customer savings model for a hotel, reusing water for toilets and irrigation
  • Unit cost and pricing: treatment plant, MBR + UV reuse train, storage and dual plumbing, plus an annual service fee
  • 24-month P&L and cash curve
  • Break-even sensitivity grid

Outcomes

  • A model that shows where the idea breaks even, with illustrative defaults

Deliverable

Scenario model.
