FIXED NETWORK MONITORING 2
• Fixed acoustic sensors permanently
monitor network
• Easy installation with ‘plug & play’
technology.
• All types of pipe work, AC, metal &
plastic.
• Acoustic correlation provides high
accuracy leak detection
• Data transfer via mobile data to
desktop interface.
Aquarius Spectrum
“A highly advanced cloud based acoustic leak detection system – offering coverage 365 days a year”
MOBILE LEAK DETECTION
iQuarius – Smart Phone Leak Noise Detection & Correlation
LISTENING
SURVEYING
CORRELATION
RECORDING
SHARING
Android application available through Play
store
User interface with each survey point rated and
graded
Each survey point is GPS located, time
stamped with individual sound files
Data recorded locally, presented & analysed
on the server
Easy to use and quick to deploy.
Allows for cross skilled field engineers with
little or no leak detection experience
CASE STUDIES
HagihonHagihon Company Ltd.
Israel’s model for a
Smart Water Utility.
KNOWING THE PROBLEM 5
• Hagihon, Israel supplies water & sewage to
Jerusalem, Mevaseret Yerushalayim and Abu Gosh.
• Water supply always a major problem
• Intricate network of ancient aqueducts, tunnels,
pools and cisterns found in the city.
• Population 1million plus.
• Water network 1,332 km
• 110 DMA’s and growing.
• Near real-time monitoring of DMA’s
• Aquarius Fixed Acoustic Leak Detection System
• To pinpoint hidden leaks & partially closed valves.
• 2,800 sensors installed.
• Reduced NRW leakage by 18%
• DMA Cardiff area
• 900 properties.
• 5km mains pipes.
• MNF 10 m3 per hour.
• NRW increasing from October 2015
• Leak detection work increased in February 2016
with no noticeable changes in leakage.
• Cumulative detection costs to 03/17 c. £2k.
• Leak repairs and costs increase as detection work
is being carried out.
• Cumulative repair costs to 03/17 c. £35k.
• No improvement to MNF
Background
PILOT – CARDIFF, SOUTH WALES
• Day 1 Design and Build
• Day 2 18 sensors installed in the field
forming a Fixed Monitoring Network.
• 3G Connected to servers.
• Day 3 - 4 Daily detection analysis
starts
• When high intensity leak noise
detected sensors correlate.
• 3 correlations received from each
couple every night between 1am and
3am.
Implementation
PILOT – CARDIFF, SOUTH WALES
• The system identified 5 POI’s,
mapped them with icons and
relevant information.
• Each sound was downloaded as a
.WAV file and listened to by the
Leakage Analyst.
• Field technicians sent out to verify
leak with iQuarius Mobile Leak
Detection.
Detection
PILOT – CARDIFF, SOUTH WALES
• 5 points of interest verified
• Correlated leaks with intensity
levels displayed on system map
• Works order request generated
and sent to field team.
Field Verification
PILOT – CARDIFF, SOUTH WALES
POI 1
Llandaff Clinic
PILOT – CARDIFF, SOUTH WALES
• Leak confirmed and marked up.
• Leak on main supply.
• Positioned on tarmac carriageway.
• Parked cars present and by noisy
junction.
• Leak flow rate 10m3 per hour
• Pressure has also seen an increase as
a result of the repair.
