The HydroSelf® Gate Flushing System from Steinhardt is a powerful sewer cleaning technology that uses a large-volume flushing wave created by rapidly opening a gate. It is ideal for long or heavily contaminated sedimentation tanks. The gate remains closed during the filling phase and opens fully in one stroke, creating a dynamic wave that cleans the tank bottom.
