Calming Shafts
Energy Dissipation Shafts for Controlled Flow Dynamics
Efficient Reduction of High Flow Velocities
Efficient Reduction of High Flow Velocities
Energy-dissipating manholes represent the optimal solution for reducing high flow velocities. They are designed and constructed to allow water to flow tangentially into the manhole and travel along the circular manhole base toward the outlet pipe located at the bottom.
These manholes are available in two different diameters—DN800 and DN1000—and in various heights of up to 5 meters. With proper installation and the use of the requisite manhole cover, these units can be installed in areas subject to traffic loads.
The manholes can be prepared for the connection of PVC, PE, ribbed, or any other type of piping.
BENEFITS OF ROTO ENERGY-DISSIPATING THROTTLING MANHOLES:
• ROTO retention basins are manufactured from the eco-friendly material polyethylene [PE].
• They are easy to install and can be situated within roadways.
• They facilitate cleaning and maintenance, as well as easy access to sewer lines.
• Available in two diameters—DN 800 and DN 1000—and in heights ranging from 1.25 m to 3 m.
• Manhole design featuring a side-outlet configuration.

FAQ
They serve to reduce high flow velocities in drainage systems, thereby preventing erosion and hydraulic overloading.
The water flows tangentially into the shaft and is guided in a controlled manner along the circular shaft floor toward the outlet, thereby effectively dissipating energy.
The energy-dissipating throttle shafts are available in nominal diameters DN 800 and DN 1000, as well as in various heights of up to 5 m.
The shafts can be prepared for the connection of PVC, PE, ribbed, and other pipe systems.
