At a glance
Client: Eldora
Sites: 2 catering facilities
Sensors: Droople Smart Flow Mono & Twin
Platform: buildingOS
The challenge
Eldora wanted to know the water impact of its operations: how much washing reusable cups really costs and where kitchen practices waste water.
What we installed
- Smart Flow Mono & Twin — on the tunnel dishwasher, over-the-range dishwashers and washing stations
What the data showed
13 cl per cup
The water used to clean each reusable cup, measured.
Thawing with hot water
A practice that wastes both water and energy.
End-of-shift peaks
Excess water use at certain times, especially at the end of the shift.
Results
- Water footprint per reusable cup quantified
- Wasteful practices identified for staff training
Thanks to Droople's solutions, we have been able to analyze water consumption. We determined the water used to clean the reusable cups: 13 cl/cup. We have identified practices such as thawing with hot water. We have noted excessive water use at certain times, especially at the end of the shift.

The takeaway
In a kitchen, the biggest savings come from habits, and habits only show up in the data.
