Sewer Flushing System HUBER Power Flush® - 2 / 4 Pages

➤ The situation

The main reasons for the ever increasing sedimentation
at the bottom of sewer systems and stormwater retention
sewers are an insufficient sewer base slope, regular
retention combined with slow flushes and a low flow
velocity. As a result, the sediments will harden over the
course of time and frequently such hardened material
layers can be 30 cm thick or even higher. The subsequent
reduced sewer cross section impairs the system efficiency
so that the solids will settle and the already sedimented
solids no longer be remobilised and transported. Negative
effects are the increase of stormwater overflow quality
and quantity discharged into the receiving water courses,
high peak loads arriving at the wastewater treatment
plant due to suddenly breaking away sediments, odour
annoyance and sewer damage caused by sulphur

Extensive hardened sediments on the sewer bottom

➤ The solution

The innovative HUBER Power Flush® has been developed
for operators of sewer systems and sewers with storage
capacity and overflow. The patented sewer flushing
system allows for complete removal of sediments in
sewers and even prevention of potential future sedimentation. Activation of unused sewer capacity and easy
retrofitting of the complete system without interruption
of the sewer operation result in additional advantages.

The flush water volume and impoundage level required
are determined for the specific sewer length and diameter and additional project-specific parameters and
taken into account in the further planning process.

Sewer cleaning is based upon the principle of sewer
flushing enabled by built-in flap gates. The required flush
water volume is generated by impounding the water
against an invert step so that sedimentation in the upper
retention area is prevented. Additional openings for
installation or special manholes are not required.
The special gate design generates a self-cleaning action
during the flushing process and prevents tressing at the
gates. Sediments in the gate area that may be caused by
the flushing medium or impoundage time are also removed due to the formation of a downsurge wave. The
integrated custom-tailored system control enables a
controlled and the maximum available cleaning efficiency
of the sewer section to be achieved.
