REAL-TIME NETWORK MONITORING TO REDUCE

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?
