Hydro-Brake Flow Controls

To deal with high rain events Resolute Engineering Group offer a range of WRC approved and BBA certified flow control devices to control the discharge of water from your drainage network in line with SuDS.
Vortex flow control devices are highly reliable, due the lack of moving parts, yet very accurate due the site-specific design which ensures accurate discharge rates that have been independently evaluated, tested and certified by BBA.
