“Infotec” are also proud to introduce
“FLUSHER”
A unique innovation
and step forward in
sewer & culvert
cleaning technology
Where and why does silt build up?
There is insufficient flow or flow velocity
Which most commonly results from:
Poor design or poor construction
Physical obstructions or blockages
Backwater effects
Existing silt deposits
Infotec look for a solution
Infotec engaged to investigate silt and fat problems in public sewers and similar drainage infrastructure
Investigation undertaken of every current method of avoidance and remedial solution
Expertise gained the hard way
Flusher is a simple solution based
upon proven hydraulic principles
Basic hydraulic principles and techniques pioneered by the Romans and regularly and successfully used by the Victorians have been redesigned and fabricated using modern materials and advanced technology
Where to install Flusher
A fixed or removable gate is installed inside
an accessible manhole chamber allowing
ease of access, ease of installation and ease
of removal
How does the system work?
A counterbalance gate that tips when rising water overcomes the weight at it’s base
When the flush has passed and flow subsides the gate snaps shut
The cycle repeats typically between
30-100 times per day
What is the cleansing process?
The repeating tidal
wave lifts and
mobilises silt and
debris over
considerable
distances
It cleans through a
process of gradual
erosion
Surely attenuation
can result in a blockage?
Here we have the Laws of Physics working in our favour.
You cannot compress a liquid and with the gate in a closed position backwater effect prevent silt progression until tipping occurs
Surcharge or tipping levels can be changed and the weight of rising water activates a simple lever which overcomes any likely obstruction
In the event of a storm or high flow
conditions, what then?
The gate lies in a flat or neutral position allowing
storm flow to pass unimpeded
Surge flows can also pass over or around the
gate due to its location inside a manhole
Fat the major cause of
sewer blockages today
Fats, Oils and Grease;
“FOG” enter sewers from
kitchens, restaurants and
private homes
Flusher attenuation allows
automatic dosing of
“Greasebuster” enzymes
eradicating FOG and
preventing further build-
up elsewhere in the
drainage catchment
Flusher and Grease Buster
By preventing conditions like these
Flusher saves money and more
Millions of pounds saved
annually by every WaSC
Reduced OPEX and
CAPEX expenditure
Reduced blockage
occurrences and a
reduction in properties at
risk of flooding
Improved SIM Scores
Compare the environmental
benefits with existing techniques?
Conventional cleansing utilises mains water
Damages drains and sewers
Causes damage to roads footpaths and verges
Pollutes the atmosphere
High noise levels
Flusher environmental benefits
Flusher is a purely mechanical system.
Operates 24hrs a day, 365 days a year
Requires no water other than the flow already in the pipe
No damage or noise
Reduced mechanical plant resulting is carbon credits
OPEX BENEFITS 25% Cost saving to Sewerage Utilities by alleviating recurrent blockages or cleansing
More than 50% Cost saving cleaning Highway drains achieved due to reduced Traffic Management and lane closures etc.
Even greater cost savings achieved on Rail networks where limited work opportunities and mobilisation of plant results in extremely high remedial costs
Plus infrastructure cleaned effectively every time
Benefits also extend to
Flood Alleviation
Flusher systems can now to be used to attenuate flow in the upstream extent of any catchment maximising storage capacity and reducing the potential for flooding
Flusher has developed a unique way to retain and slow the delivery of storm water
Water retained and stored in the
upstream extents of a River
Flusher utilises unused
capacity in drainage catchments
By installing a series of
Flood Defence Flusher
systems within the
upstream extent of any
drainage catchment
effluent is stored within
the unused upstream
capacity slowing its
progress and protecting
at risk properties and
low lying areas
Unimpeded dry weather flow
Retained storm flow prior to
Flusher rotation
Offline tank storage can become
a thing of the past
Blighted land, and
unnecessary
maintenance are two
compelling reasons
why a lower cost
Flusher solution
negates the need for
offline storage
Online replacement or upsizing
a more effective solution
Where the existing catchment capacity is insufficient, online enlargement is in most cases a simpler, more convenient and cheaper solution. This can often be achieved whilst maintaining the normal operation of the network.
