Upon returning from his Christmas break, the energy manager of a municipality found an alert from Ento’s Water Advisor. Right before the holidays, the water baseload at a local preschool had started to noticeably increase.

After an investigation of the building, a faulty toilet was determined to be the culprit. 250 litres of water were being lost per HOUR, costing the municipality 5,000 DKK in just two weeks.
