Stormwater filtration

SDS Aqua-Filter®, in conjunction with SDS Aqua-Swirl®, is a hydrodynamic separation and filtration system for the removal of fine sediments, nutrients, heavy metals and hydrocarbon pollutants from surface water runoff. Aqua-Filter® can be used as part of a complete surface water management programme, for example, when connected downstream to a

SDS Aqua-Swirl® is a hydrodynamic separator used in water management systems to capture pollutants, such as oil and debris, within surface water runoff. It can effectively eliminate more than 80% of total suspended solids. SDS Aqua-Swirl® can be connected to a stormwater attenuation or infiltration system, such as a SDS GEOlight® geocellular

StormCleanser™ is a hydrodynamic separator designed to treat surface water run-off by removing pollutants including floatables and sediment. It integrates into precast concrete drainage chambers and is used within SuDS systems to improve water quality. The system creates low-energy vortex patterns, separating contaminants from the water. A baffle

Aqua-Xchange™ uses ionic exchange and filtration to remove soluble and solid pollutants from surface water run-off. It comprises naturally occurring, loose granular materials that maximise the pollution adsorption process by enabling stormwater to percolate through its large surface area. This prevents surcharging and allows sufficient contact

The Hydro Biofilter™ bioretention system captures stormwater runoff and naturally treats the pollutants. It significantly improves upon traditional bioretention and biofilter designs by combining specialist engineered media with shrubs or trees to provide enhanced bioretention and biofiltration in a kerbside device. The advanced design requires

The Up-Flo™ Filter is a high rate, modular stormwater filter system that combines a patented upward flow path with a unique drain down design. It is designed specifically for removing a wide range of pollutants, including floatable debris, fine sediments, nutrients, metals, oils and grease, organics and bacteria, from stormwater. The Up-Flo

From residential to industrial and infrastructure projects, the ACO StormSed Vortex removes pollutants such as floatable and sediment bound contaminants from surface rainfall. The removal of sediments from surface water is a crucial stage of a suds project, with around 75 percent of chemical pollution, such as metals and residual oils bound to

ACO StormSed Filter is a proprietary surface water filtration system designed to remove total suspended solids, heavy metals, and hydrocarbons from runoff. Suitable for high pollution areas up to 3000m², it is made for sites with limited space or where green infrastructure is not feasible. Units are available in a range of sizes to suit different

Storm King® is an advanced hydrodynamic vortex separator and screen that delivers exceptional removal of total suspended solids (TSS), biological oxygen demand (BOD), gross solids and floatables at combined sewer overflow (CSO) sites, preventing damaging pollutants from reaching the environment. Storm King® screens and removes 100% of solids

Downstream Defender® Select is a hydrodynamic vortex separator made for stormwater treatment, capturing and retaining sediment, oils and floatable debris from runoff in a compact unit. Customisable chamber sizes and inlet options support a range of flow rates and pollutant removal standards

StormTank™ is an underground precast concrete attenuation system made from wall panels, a concrete base and cover slab, assembled on-site. Designed for water management, it can be configured with pipe connections, openings and internal features such as weir-walls and baffles. Maximum height is 6m with a 2m overburden, it suits pedestrian and

SDS delivered an integrated water management solution that addresses the potential for flooding and seasonal shortfalls in water availability at Babraham Research Campus near Cambridge, a globally-important research cluster and one of the UK’s leading locations to support bioscience enterprise. The development has been able to demonstrate a substantial net gain in biodiversity

The precarious wetland habitat at Shortwood Pond off the A308 by the Crooked Billet Roundabout is home to endangered species such as the Brown Galingale plant and the Little Whirlpool Ramshorn snail. It is part of Staines Moor, located at the eastern end of Colne Valley Park, which contains many Sites of Special Scientific Interest. Project

FP McCann’s back-bolted segmental shaft rings have been used to build a 20m id storm overflow holding tank as part of Yorkshire Water’s project to improve the water quality in Pudsey Beck. Once complete, the works at Dick Lane Bradford are forecast to reduce storm overflow discharge by up to 65%. Yorkshire Water is making planned improvements to a

The objective of this project was to help improve the ecological status of Beverley Brook, which runs through Richmond Park on its way to join the River Thames. As part of Beverley Brook Catchment Partnership plans a Downstream Defender® was installed to remove litter, oils, and fine and coarse sediments from urban road run-off, preventing them

Eastern High School, a new centre for secondary and further education in Cardiff, opened in 2018. It can accommodate 1200 school pupils and a further 320 college students. SDS was required to effect the fast and efficient removal of surface water from the site and to ensure its safe dispersal to natural water receptors. As works were being carried

BDB Special Projects installed SDS Aqua-Xchange™ granular treatment media into an existing filter drain along the M56 to prevent pollution of a vulnerable stream, which receives run-off from a 1km stretch of the motorway via a single outfall. Aqua-Xchange™ is designed to capture and retain copper and zinc, poisonous metals released through the

As part of a multi-million pound ‘Phase III’ development and extension of Prologis RFI Daventry International Rail Freight Terminal (DIRFT), SDS was required to effect the fast and efficient removal of surface water from the site and to ensure its safe dispersal to natural water receptors. This meant ensuring that the site complies with all

FP McCann has designed and installed a 315m3 precast concrete StormTank extension on behalf of client Yorkshire Water and project contractor Seymour Civil Engineering at Tadcaster Sewage Treatment Works (STW). The FP McCann StormTank extension is part of Yorkshire Water’s £180 million drive to reduce the frequency of stormwater overflows from its

The Thames Riverside development is a £26 million business park on the south bank of the River Thames in Staines, on a 5.65-acre site along the Causeway. The mixed-use scheme combines a 64,000 sq ft "Big Yellow" self-storage facility, a six-unit, 6,000 sq ft Innovation Centre, and nine industrial units totalling 100,000 sq ft, set within an area

One of the first UK installations of the innovative new Hydro Biofilter™ bioretention and biofiltration system has brought attractive landscaping and stringent stormwater quality control to a sensitive location in Barry, South Wales. Vale of Glamorgan Council decided to install three Hydro Biofilter™ units from Hydro International at the Business

Central Quay occupies a 4.4-acre site in Glasgow's Anderston district, next to the River Clyde. The site was formerly home to the Harland & Wolff Finnieston Diesel Engine Works and had remained derelict for over half a century before the current redevelopment began. The scheme involves the modernisation of an existing 80,000 sq ft office building

The M4 is the primary arterial route across South Wales, linking west Wales, Cardiff, Bristol and the wider UK road network. Congestion and environmental pressures along the route, particularly around Swansea, have long concerned commuters, businesses and policymakers. Sections between Junctions 43 and 47 were earmarked for improvements to boost

Highway degradation and surface water pollution in an environmentally sensitive area of the Scottish Cairngorms Mountains famous for its whisky production have been tackled with an imaginative SuDS Solution from Hydro International which has averted potential road safety problems on the A95. Poor drainage, flooding and freezing weather had led to
