REAL-TIME NETWORK MONITORING TO REDUCEFLOODING-OTHER-CAUSES EVENTSDr Peter Skipworth
• Flooding Other Causes (FOC) events
an industry challenge
• Real-time monitoring in sewers to reduce FOC events
the JITOM approach
• JITOM explained
• Where are we with JITOM?
PRESENTATION
Flooding Other Causes (FOC) events
AN INDUSTRY CHALLENGE
• Cause
Blockages
silt, sewer solids, debris, FOG
Collapses
full or partial
Equipment failure
e.g. non-return (flap) valves, pumping
stations, penstocks, screens
• Effect
FOC and pollution incidents: internal, external
Fixed point source pollution
SEWER FAILURE: CAUSE AND EFFECT
• Latest June returns show ~4000
internal sewer flooding incidents p.a.
• Further reductions are potentially
very expensive
e.g. OFWAT assumed £1.1bn to
reduce sewer flooding registers
by at least 1,300 from 2012-14
INTERNAL FLOODING: AN INDUSTRY CHALLENGE
• Technological approach now seen as key:
“The use of monitoring technology and
associated data analytics is implicit in
meeting our objectives”, Thames Water
Severn Trent “is intensely looking at
monitoring technologies for wide-scale
application”
• UKWRIP Htech0 Report
$20-35 billion – the potential worldwide
market over the next 6 yrs for smart flood
protection combined with SUDS for road
and surface drainage

Where are we?
• Theoretical testing complete
• Concept proven
• Potential equipment In use in other countries
ATEX certified
Price point being challenged
Working on R&D with suppliers on further development inc. new sensors.
• Software platform in place
• Scoped a pilot with Water Companies, discussing with others
WHERE ARE WE NOW?
