Repeatable Performance, Inspired by Nature 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, Hydro’s treatment systems can deliver sustainable solutions which enhance – and even outperform nature itself. 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...

First Defense® Vortex Separator The First Defense® is an economical hydrodynamic vortex separator for effective removal of sediment, litter and oil from surface water runoff. Captured pollutants are kept safely within the device keeping public areas free from harmful pollutants. Suitable for at-source pollution control in small to medium size catchments, the First Defense® provides spacesaving, easy-to-install surface water treatment in a standard size manhole. Coarse particles Gross pollutants Liquid and sediment bound hydrocarbons Repeatable, Reliable Performance The First Defense® internal...

Case Studies Beach Sixty The smooth installation of 60 First Defense® separators at Revere Beach in Massachusetts provided a cost- and time-saving solution to removing sand, grit, litter, oil and debris from runoff along a 1.5 mile section of highway boulevard. The solution provided treatment at each drainage inlet prior to infiltration of the surface water as part of a major urban regeneration initiative. A First Defense® unit provided a much-needed small footprint solution to meeting regulatory treatment requirements on a confined site for a new commercial office development in Perkins Township,...

Downstream Defender® Advanced Hydrodynamic Vortex Separator The Downstream Defender® is an advanced hydrodynamic vortex separator for the effective and reliable removal of fine particles along with oils and other floatable debris from surface water runoff. Its innovative design delivers high efficiency across a wide range of flows in a much smaller footprint than conventional or other swirl-type devices and is the perfect choice for any catchment likely to convey high quantities of contamination. Fine particles Gross pollutants Heavy Metals Sediment bound Sediment bound Liquid and sediment bound...

Case Studies Pollution Protection in Whisky Country Sustainable Homes Infrastructure Highway degradation and surface water pollution were averted on the A95 near Craigellachie in an environmentally sensitive area of the Scottish Cairngorms thanks to an imaginative SuDS Solution using 3 Hydro-Brake® Flow Controls and a Downstream Defender®. The exemplary sustainable drainage infrastructure for the 2300-home Great Kneighton Housing Development in Cambridgeshire is based on a series of four large ponds with infiltration and settling basins located across the 109 hectare site. Downstream Defender®...

Up-Flo™ Filter Fluidised Bed Up Flow Filtration System The Up-Flo™ Filter is an innovative surface water filtration technology that delivers a high-performance multi-stage treatment train within a single device. The Up-Flo™ Filter combines sedimentation and screening with fluidised bed filtration technology to deliver high levels of performance. Easy to maintain and with low construction costs, the Up-Flo™ Filter achieves a high quality of surface water discharge in a much smaller footprint than alternative systems. Very fine particles Gross pollutants Heavy Metals Sediment bound Sediment bound...

Case Study Natural SuDS ‘Not Possible’ A unique solution for a new homes development in Kent enabled SuDS with two levels of treatment for a new access road, combining Up-Flo™ filtration technology with Hydro Stormbloc® modular storage and infiltration blocks. A custom-modified Up-Flo™ Filter provides effective settlement, screening and filtration to meet Environment Agency water quality requirements while also satisfying the maintenance needs of the highways authority. To meet the surface water discharge constraints for the site, the final discharge from the filtration unit is infiltrated into...

Hydro Filterra™ Bioretention System The Hydro Filterra™ is an innovative bioretention and biofiltration system that harnesses the natural treatment action of vegetation and the filtration power of speciallyengineered soils. From the surface Hydro Filterra™ looks like a tree box, with a suitable shrub or small tree protruding through a decorative grating in a concrete slab at pavement level. Underneath, the pre-cast concrete chamber contains a layer of enhanced mulch, on top of a unique soil filter medium to deliver high levels of surface water treatment. Very fine particles Gross pollutants Heavy...

Case Study Stringent Quality Control, Naturally Hydro Filterra™ have brought attractive landscaping and stringent surface water quality control to a sensitive location in Barry, South Wales. Vale of Glamorgan Council retrofitted three Hydro Filterra™ units at the Barry Business Support Centre car park to upgrade the site to meet SuDS requirements and provide urban planting and landscaping for much-needed urban regeneration. This typical urban location is surrounded by buildings and infrastructure and the three Hydro Filterra™ units enabled Environment Agency requirements to be met for removing...
