A device that allows consumers to monitor consumption on a regular basis and in quasi real-time (FT)
Automated meter reading
Advanced metering infrastructure
Information is key to management The Smart Water Meter is a tool to provide the required data Features • Electronic meters with
communication • It can be a mobile or fixed
communication network • Generates intelligent alarms
providing additional info on leaks, dry, burst or tamper conditions
• Detailed data about water usage • Historic data kept inside the meter
for verification
Smart meter
Automated meter reading the first step? Collection of information but no control Features • Handheld or drive by options • Intelligent alarms from the
meter (delayed) • Data about water
usage(delayed)
AMR
Advanced metering infrastructure the BIG step? Collection of information but usually with control Features • Fixed infrastructure • Bi-directional communication • Data near real time • Alarms picked up much earlier

Global challenges in water
• Total cost NRW worldwide conservatively estimated at
$14billion per year
• 45 million cubic meters are lost daily through water leakage in the distribution networks(developing countries)
• Enough to serve nearly 200 million people.

Global challenges in water
Looking at the global challenges in water we need to find new sources of water or we need to find smarter ways to manage what we have.
Managing the problem
In a 2014 survey Water Utilities mentioned leakage as their top challenge
Water Utility top challenges
Challenge 1: Real Losses
12 DHI 2016 conference
Can smart water meters assist with leakage detection and prevention?
District metering area
13 DHI 2016 conference
Volume Water Temperature Ambient Temperature Infocodes „- Leak - Burst - Reverse flow - Tamper - Dry
Pressure Pressure Surges Infocodes
DMA Volume DMA Water Temperature DMA Ambient Temperature DMA Infocodes „- Leak - Burst - Reverse flow - Tamper - Dry
Challenge 1: Leakage – District metering area implemented
With this information a utility can quickly determine where a burst is occurring within a DMA

Managing Real Losses Can smart water meters assist with leakage detection and prevention? Yes.
“After changing from mechanical to smart meters we document consumption precisely, more than a year back in time. Providing evidence at an early stage helps settling disputes. Consumers have more trust in our meter readings now.” Eyvind Holst, Chairman, Toerring Water Company, DK
SA challenge not only leakage
17 DHI 2016 conference
Can smart water meters assist with NRW apparent losses in South Africa?
Managing the problem
Managing the problem
Managing Apparent Losses • Customer meter inaccuracy Smart ultrasonic meter accurate for up 16 years. No wear and tear and
no maintenance. • Unauthorized consumption, illegal connections, theft and fraud System water balance can be done every hour within DMA so increase in
unauthorized consumption can be identified and corrected • Data collection and transfer errors between meter and the billing system Fully automated from meter to billing system
“It used to be extremely difficult to localize leaks. First test reading of 255 new smart meters detected 3 leaks; two hot water tanks and a bath-room pipe.” Dennis Schrøder, Operational Manager, Hjerting Electricity and Water utility, DK
Water management
Water management Important? ..or just a ticket to the rugby?
20 DHI 2016 conference
• Smart meters are efficient in minimizing non revenue water. • Smart meters can improve customer
service. • The smart meter is a perfect tool for
water conservation.
