How to addresses the waste?
WATER CONSERVATION• Manage the increasing demand for water
• Reduce water losses
• Engage consumer in conservation efforts

•Total consumption in 21\7\2010 = 99909.5 m³.
•The meter was reversed in 27\7\2010.
•Then the meter was reinstalled again in the right position on 15\8\2010 at 10am. Total consumption = 99879 m³
•Total volume consumed during the time the meter was reversed is 121.274 m³ (29 m³ for the above mentioned duration + 95 m³ accumulated backflow)
•This Fraud was costing the Utility 1,140 m³ / year
TAMPER/FRAUD Detection
This example is about a real life tampering situation where the water meter was Re-Installed by the tenant to reduce the large consumption index of the meter.
