HydroFlush®

Automatic sewer flushing

With increasing demands upon sewer maintenance budgets, the ability to maintain a comprehensive
flushing regime in sewers with slack gradients can become increasingly difficult. Siltration
within sewerage networks can lead to reduced hydraulic capacity, flooding and odour problems.

The HydroFlush flushing system is a highly effective cleaning system for small bore
sewers up to 400 mm diameter and can be arranged as follows:

• Water supply connected via road gulley, so that it operates during wet periods, to maintain silt flushing.
• Water supply controlled by ‘time controlled valve’ to operate in a controlled manner, in dry weather conditions.
