New Hydro StormTrainTM Series - a SuDS-Compliant Toolbox for Surface Water Treatment
The Hydro StormTrainTM Series, a comprehensive toolbox of surface water treatment devices in anticipation of the growing need to remove silts, sediments and other pollutants from stormwater runoff.
Through The Hydro StormTrainTM Series, Hydro is providing an unrivalled range of performance-verified and internationally-recognised technologies for surface water treatment to meet current and expected water quality regulations in the UK.
Four products, First Defense®, Downstream Defender®, The Up-Flo™ Filter and Hydro Filterra™, are Sustainable Drainage Systems (SuDS) that can be used independently or in combination to deliver a Treatment Train that meets the water quality stipulations of a site. They can also be used to protect, enhance or enable natural SuDS features.
The expectations of the EU Water Framework Directive (WFD) are influencing the development of surface water quality regulations in England, Wales and Northern Ireland, as well as driving the implementation of established regulations in Scotland. In every case, Hydro’s treatment devices offer future-proof SuDS-compliance.
In England and Wales, SuDS will be compulsory for new developments of more than one property from April 2014. New Local Authority SuDS Approving Bodies (SABS) will assess drainage schemes according to new National Standards that are likely to include expectations for water quality and pollutant removal.
The First Defense® is an economical vortex separator that removes coarse particles, litter and oil from surface water runoff.
The Downstream Defender® is an advanced hydrodynamic vortex separator that removes fine particles along with oils and other floatable debris from surface water runoff.
The Up-Flo™ Filter combines sedimentation and screening with fluidised bed filtration technology to deliver a high-performance multi-stage treatment train within a single device.
The Hydro Filterra™ bioretention system combines the natural treatment action of an ecosystem with specially-engineered filtration soils in an easy-to-fit concrete unit.
Hydro has developed a unique online Treatment Selection Tool to help explore the consequences of combining proprietary and natural SuDS techniques in a variety of applications. Free to use at www.hydro-int.com/stormtrain/tool, the tool helps users develop ‘what if’ scenarios and build example treatment trains, then calculates potential outcomes in terms of pollutant removal and cost implications.
