Overview 

The Hydro-Brake® Orifice flow control provides water quantity management for surface, foul or combined water at sites with generous discharge consents and low storage constraints.

A low-cost, low-complexity flow control, the Hydro-Brake® Orifice is a precision-cut, sharp-edged orifice plate flow control that delivers precise, cost-effective sustainable and low-impact drainage.

With no moving parts and no power requirements, the Hydro-Brake® Orifice is a low-maintenance drainage solution that is ideal for development-scale flow control at sites with moderate flows and moderate storage options.

Designed for

Medium flow

Medium storage

Benefits

Deliver affordable low-impact drainage

The Hydro-Brake® Orifice is a simple, economical flow control device that enables designers and developers to manage water as part of a sustainable, low-impact drainage system. Where discharge consents are high and storage constraints are low it may offer a cost-effective alternative to the custom-designed water quantity management provided by a Hydro-Brake® Optimum flow control.

Get approval and adoption

As a precision-engineered, proven component of a green infrastructure toolbox, the Hydro-Brake® Orifice flow control helps developers to demonstrate compliance with low-impact drainage guidelines to planning and adopting authorities, making it easier to obtain approval and adoption for residential, commercial and industrial developments.
