Remote monitoring of reverse osmosis units in coffee shops: about €15,000 saved in service costs for one customer
At a glance
Client: WPG Water Purification UG
Sites: coffee stores of a franchise chain across Germany
Assets: reverse osmosis (RO) systems producing beverage water
Platform: filtrationOS
The challenge
WPG installs RO systems that produce the water used for coffee and drinks. Without live data, quality drifts and failing units were only found during site visits or after a complaint.
What we installed
- Droople Trion — flow and water-quality monitoring on each RO unit
- Pressure sensors — inlet and system pressure
Alarms that did the work
- Conductivity too high or too low · permeate quality out of range
- Pressure anomaly · membrane or supply issue before a breakdown
What the data showed
Quality you can prove
Permeate quality is tracked continuously for every store.
Visits when needed
Technicians go out on alerts instead of fixed rounds.
Results
- ≈€15,000 saved in service expenses for one customer
- Preventive maintenance and timely interventions
Based on our operational experience, we estimated that one of our customers have saved approximately €15,000 in service expenses thanks to the implementation of the Droople monitoring solution!

The takeaway
For a water treatment provider, remote RO data turns service from routine visits into targeted interventions.
