Solution chosen by Northumbrian Water (NWL) was storage with Hydro International's Hydro-Brake Flow Control to attenuate the discharge into the local sewage treatment works
The joint venture between CPM and Hydro is a collaboration between the UK's market leader in the manufacture and supply of concrete drainage systems and the designer and manufacturer of innovative, minimal maintenance, low power hydrodynamic stormwater and wastewater quantity and quality control solutions.
The Hydro-Brake Flow Control regulates liquid flow by using upstream head to generate a flow-limiting air-filled vortex which ensures a constant maximum flow of water despite a fluctuating head.
The device achieves its maximum design flow at a much lower head than the equivalent orifice plate or other standard control device.

A further benefit of the Hydro-Brake design is that it has no moving parts and needs no power, so operating costs are very low.
The opening is between three and six times the size of equivalent flow orifice plates or penstocks, so it is not so prone to blockage; maintenance is therefore minimal.
The Downstream Defender is a packaged hydrodynamic vortex separator system which removes grits and silts, suspended solids, oil and grease from building developments, construction sites and access road washdown or stormwater runoff.
It is ideal for new or for upgrading existing sites, and the resultant water quality generally enables it to be discharged directly to watercourses, eliminating the requirement for lagoons and treatment ponds.
The Downstream Defender comprises a reinforced concrete chamber, fitted with co-polymer polypropylene internal components.
Its high efficiency, minimum headloss, no power requirements, no moving parts and low maintenance are ideal for low environmental impact pollution prevention.
