Water Sector Innovation – The Problem
• To deliver a solution, you need to understand the problem.
• Sewage Pumping Stations - What is the problem people want to solve?
• to minimise spillage incidents
• to stop ragging blockages
• to ensure efficient operation of pump assets
• to reduce maintenance time
• to reduce energy consumption
• to protect staff from exposure to raw sewage
• to improve the customer experience
• What must the solution deliver?
• it must be available as a retro-fit
• it must be easy to implement
• it must be easy to use
• it must be easy to maintain
• it must be future-proofed
• it must be available as an incremental solution or a full network solution
• it must be intelligent, record data, and facilitate proactive maintenance
• it must have a positive impact on the customer
• it must be proven

Solution = DERAGGER II
What does it do? = INTELLIGENTLY STOPS PUMPS BLOCKING
How?
• Performs wave form analysis of pump power consumption
• Allows real-time detection of when the first rag impedes the impeller
• Simple electronic retrofit device to almost any control panel
• Works with any starter type
• Prevents rag-balls forming
• Keeps rags in suspended flow
What Benefits Does it Deliver?
• Dramatically reduces/eradicates need to lift and clean pumps
• Reduces energy consumption
• Reduces likelihood of spillage
• Delivers more even current to pump
• Increases flow
• Reduces run-time
• Extends asset life

4. INTELLIGENT EFFICIENCY.
Solution = DERAGGER II
What does it do? = DELIVERS NETWORK EFFICIENCY
How?
• Collects real-time operating data on all aspects of pump operation
• 74 monitored variables
• Real time data is available to feed/interface into your existing telemetry
What Benefits Does it Deliver?
• By spreading across a network the whole network pump asset base can be monitored
• Can be used as a preventative device – do not wait for pumps to trip
• Rags can be kept in suspended flow across whole network and passed constantly through
to screens (avoids collected rag balls being flushed though during storm events)
• Such comprehensive real-time data monitoring provides the capability to develop full
planned maintenance cycles

Water Sector Innovation – What do clients say?
• “Generally, it has been found that the use of reversing technology allows pumps to maintain a higher
operating efficiency through operating rag free, which also reduces the number of maintenance visits
required, without any detrimental effect to the impeller securing arrangement. It appears my initial
scepticism was unfounded, and I would encourage keeping an open mind on the adoption of technologies
that challenge old established beliefs, and which have the potential to return benefits, as in this case.”
– Bryan Spence, Scottish Water- Senior MEICA Strategist
• “There is mounting evidence that the real-time detection and alleviation of pump blockages via wave
form analysis (of the power input to the pumps) is generating quantifiable cost reductions and energy
efficiencies. As an independent research organisation, we are now working with the water industry to
verify the magnitude of these benefits.” – Leo Carswell, Water Research Council – Head of Technology
• “The Deragger II not only kept our pumps rag free they have allowed us to remove the inline
macerator, thus saving energy, maintenance costs and preventing the upstream screens from blocking.
This is probably the best piece of equipment we have installed at our plant.” – Steve Jones, Welsh
