Vortex Flow Control System

Vortex flow control system

Individually designed and configured

Our vortex flow control systems are designed to regulate storm water flow before it discharges into the watercourse or sewer networks.

The vortex flow control system is capable of regulating any flow for surface water applications and can be used in conjunction with retention and attenuation systems as an integrated sustainable urban drainage (SuDS) scheme.

The Vortex flow control is a horizontal flow control system designed to regulate 1-100 litres per second, manufactured from grade 304 stainless steel, each system is individually configured to suit specific performance criteria.

How does Vortex Flow Control work?

The design of the vortex flow control is based on the fluid mechanics principle of the forced vortex, which permits flow regulation without any moving parts.

The vortex flow control utilises the upstream head and discharge to generate a ‘vortex’ within the structure of the unit.

The water is then released at a pre-determined controlled rate preventing downstream flooding.

Unlike more conventional methods the vortex flow control system is less prone to blockage and permits higher flow at lower head, vortex control allows an outlet 4-6 times larger in cross sectional area to be used.

Why choose a Vortex Flow Control System?

Planning and connection – addresses the planning and connection requirements set out in the Floods and Water Management Act.

Tailored performance – tailored to the specific performance requirements of the application.

Optimum hydraulic efficiency – the mechanism employed within the vortex flow control provides superior hydraulic performance in traditional flow control systems.

Water Authorities Approval – approved for use by a number of water authorities.

Proven performance – UK manufactured and independently laboratory tested to verified discharge rates.

Simplified access and maintenance – large clear openings making it less prone to blockage, the absence of any loose parts also reduces maintenance requirements.

Patented bypass door and emergency drain down facility allows the vortex flow control to be accessed from the surface to allow the upstream system to be independently drained, completely bypassing the inlet.

Reduces total installed cost – allows more flow at lower heads, reducing the need for on-site storage volume requirements lowering installation costs.

Ease of installation – Vortex flow control is custom built to suit the profile of the chamber. Radius fixing options remove the need for additional benching – simplifying installation and reducing cost.

WinDes – can be sized and modelled on the latest version of the design software and can be incorporated into the overall hydraulic drainage design.
