2. Pilot Study Sites

Types of Pilot Study Sites:

– Public toilets

– Mosques

– Parks

– Public sport facilities

– Graveyards

– Schools

– Universities

Criteria for selecting pilot study sites:

– Size of water meters (DN 20, 25, 32, 40, 50 mm)

– Distance to the University

– Presentation of the different types of UnbilledAuthorized Consumption

– Security of meters against theft

– Protection of meters against floods, heavy rain, etc.

– Ease of installation

– Power of GSM signal

The pilot study sites were not selected based on thelevel of post meter leakages.

Installation of

Smart Meters

Smart Meters

Flow rates are monitored at each 15 minutes interval.

Monitored data sets are transferred to PC or mobile

phones by GSM.

Warning message is sent when there is leakage

If you do not pay for it, you do not

care about it


Post meter leakages should be investigated

Post meter leakages in public areas could be in

considerable volumes.

Smart meters are efficient for monitoring and detecting

post meter leakages

Raising public awareness is essential for reducing post

meter leakages
