WATER CONSERVATION • Manage the increasing demand for water • Reduce water losses • Engage consumer in conservation efforts How to addresses the waste?
International recognized classification • Itron Program to address Water Loss Reduction on Apparent loss 10-12% of Total Volume

METERING ADDED-VALUE CHAIN Intelligence from the very beginning and at every step. Data actionable starting with its creation. How data becomes useful
SMART = no longer just a meter reading 12 Nov Backflow - index Leakage detection High Peaks Values above threshold index over & under sized meter flags Values below threshold index logging intervals Automatic time synchronisation Meter reversed alarm Meter blocked alarm Time of use index Event log book

TAMPER/FRAUDDetection 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. • 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
