What we measured:

  • Cost comparisons between cans of water and the capital and maintenance costs of the Join the Pipe tap (total payback time and ongoing cost savings over a 5 year period)
  • Environmental impacts (waste and carbon dioxide emissions diverted) based on the avoidance of aluminum cans of sparkling water
  • Employee feedback and perception about the switch from cans of sparkling water to the Join the Pipe tap
