HydroFlush® Mini

Continuous channel flushing

Throughout the UK there are many sewerage networks containing sewers in low lying areas
where insufficient gradients cause siltation problems. This can lead to a loss of
hydraulic capacity within the network, loss of performance of downstream treatment
works or ancillary pumping stations.

The HydroFlush Mini Sewer Flushing shield uses impounded water to flush the down stream
sewer automatically without external power. During dry weather conditions the HydroFlush Mini
will impound the flow behind the shield, periodically releasing the flow as a flushing
wave carrying sewer debris along the invert transporting it to the sewage treatment plant.
In storm conditions the shield rises above the flow leaving the high flows to pass
through unimpeded.
