“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.
