Self-cleaning of networks: the flush gate



Control the accumulation of deposits in the sewerage network to maintain the evacuation capacity, facilitate operation and minimise the risks of malfunctions such as spills, pollution, floods, etc...

The 3D EAU solution

Carry out a diagnostic study of solid transport in order to understand the origin of the deposits and the conditions necessary for their resuspension.

When this solution seems relevant, re-suspend the settled matter using regular flushing in order to minimise deposits and therefore the cleaning operations by directing the deposits to specific extraction points.

General methodology

Step 1 - Feasibility study

Taking into account the actual hydraulic environment of the network


Characterisation of the hydrodynamics and solid transport in the network, good integration of the equipment in the existing environment

Step 2 - Design and implementation

Design, manufacture and assembly in the workshop


Physical testing on our hydraulics bench

Step 3 - Delivery

On-site delivery
