The Hydro StormTrain Series

The Hydro StormTrain® Series is an unrivalled toolbox for reliable surface water treatment in Sustainable Drainage Systems (SuDS).

The Series comprises our industry-leading surface water treatment devices, each delivering proven, measurable and repeatable surface water treatment performance. Each can be used independently to meet the specific treatment needs of a site or combined to form a management train.

Peformance-verified Surface Water Treatment

Nature can often be the inspiration for best practice in simple and sustainable drainage design in the urban environment. By engineering in nature’s way, The Hydro StormTrain® Series delivers predictable, repeatable surface water treatment performance that can enhance – or even improve on nature itself.

Four products, First Defense®, Downstream Defender®, The Up-Flo™ Filter and Hydro Biofilter™, 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.

Selecting from the Hydro StormTrain® Series of surface water treatment devices offers the advantages of:

•               Repeatable, tried and tested performance.
•               Minimal maintenance that is planned and predictable.
•               Reduced land take to maximise developer returns.
•               Buildability – pre-packaged for ease of installation with low construction costs.

Each device delivers proven, measurable performance that saves on construction and maintenance costs.   Each can be used independently, in combination, or alongside natural SuDS features.

Design Compliant Stormwater Treatment Solutions with Confidence

Our treatment devices can be designed with confidence to reliably deliver appropriate ‘levels of treatment’ as part of a SuDS management train.

Extensively Tested and Verified

Our surface water treatment devices are performance-verified for use by many independent regulatory bodies in the UK, US and other select territories around the world. They are extensively tested through Hydro’s own world-class Research and Development facilities, ensuring predictable performance to the highest standard.
