HydroFlush® Mini

Continuous channel flushing

HydroFlush Mini

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.

Advantages and Benefits

  • Preventive maintenance of low gradient sewers
  • Environment-friendly cleaning without external power, fresh water or control technology
  • Functions constantly and independent from rainwater levels
  • Can be retrofitted into existing systems
  • No separate flushing chamber needed
  • Preventing sedimentation within the sewer during dry weather
  • Prevents shock loading on downstream Sewage Treatment Works where high siltation deposits occur in rainfall condition
  • Reduces CSO discharge loadings from flat gradient sewers
  • Prevents build up of odours due to sediments
  • Reduction of gasses formed by sedimentation
