Hydro-Brake® Agile Flow Control Keeps Flood Storage to Absolute Minimum

Posted: Monday 2nd November 2015

Hydro International is launching the Hydro-Brake® Agile flow control at FloodExpo 2015, marking a significant new opportunity for engineers, developers, planners and water companies to achieve efficient surface or foul water attenuation with the lowest possible flood storage volumes.

The Hydro-Brake® Agile is a new float-activated flow control that extends the Hydro-Brake® Flow Control Series, a versatile toolbox of precision-engineered flow controls with a solution for every project and budget.

The Hydro-Brake® Agile can be engineered to achieve the lowest possible flood storage volumes in one simple, cost-effective and easy-to-install unit without any power requirements. Enabling Sustainable Drainage Systems (SuDS) compliance on new developments and highways, it can also be used to manage flows and prevent flooding in sewer networks, combined sewers and wastewater treatment plants.

“The Hydro-Brake® Agile achieves a constant rate of discharge and therefore the lowest possible upstream storage volumes,” says Phil Collins, Stormwater Sales and Marketing Manager UK and Ireland. “It is ideal for projects designed with stringent discharge requirements and where the space available for flood storage is very limited.

“Above ground, minimising flood storage avoids the use of valuable building land and minimising flood storage below ground helps solve space limitations in underground tanks, pipework and sewers. It also keeps contracting and equipment costs as low as possible.

“As the cost of a flow control is a small proportion of the total project costs, an investment in a precision-engineered device can therefore result in considerable savings, especially where space is at a premium.”

The unit’s automatic operation and predictable, repeatable performance ensure that operating costs are also kept low. The Hydro-Brake® Agile reduces the burden of long-term management and maintenance, and helps ensure acceptance by adopting authorities.

Designing an effective system using Hydro-Brake® Agile is easy using Hydro International’s free technical and design support service. Professional engineers are available to provide advice on sizing, flow and storage calculations, as well as assisting with dimensioned installation drawings.

Hydro-Brake® Agile

The Hydro-Brake® Agile comprises an orifice plate with a variable open area regulated by a float-arm operated gate to deliver a constant discharge rate over a wide range of heads. The discharge rate is adjustable to match the discharge requirements for the site.

Discharge through the open gate at low flows is unimpeded. During a storm, the float arm closes the gate until the maximum water level and discharge rate is reached for a designated event, so that the gate is prevented from closing further, despite any increases in head.

The maximum discharge rate is maintained while upstream storage is drained down rapidly, ensuring the unit is ready for subsequent storm events, until the float returns to the resting position with the gate fully open. The Hydro-Brake® Agile is easily adjustable to accommodate changes in operating conditions.

Manufactured from high-grade stainless steel, the Hydro-Brake® Agile Flow Control can be matched to a range of outlet pipe sizes. The unit can be supplied prefitted in a cast concrete chamber for easy on-site installation. To suit the location and invert required, the chamber depth can be easily varied with concrete rings.

The Hydro-Brake® Flow Control Series

Hydro International has set the standard in flow control technologies for more than 35 years. The Hydro-Brake® Flow Control Series is a versatile toolbox of precision-engineered devices for surface water control: Hydro-Brake® Agile; Hydro-Brake® Flood Alleviation; Hydro-Brake® Optimum; Hydro-Brake® Orifice.
