Stormwater Treatment

Removing pollutants from stormwater runoff is an important component of any stormwater management solution. Stormwater pollution such as sediment, oils, rubbish, debris and metals is one of the leading causes of loss in water quality.

Stormwater biofiltration combats these pollutants and Marshalls Civils and Drainage, in conjunction with Hydro International, have developed the following precast solutions:

• Downstream Defenders – downstream defender installation helps in the removal of sediment, oil and floatables from stormwater control, using an advanced vortex separator
• First Defense® – which is an effective catch basin and stormwater separator
• Up-Flo Filters – stormwater filters which target a large range of pollutants
• Biofilter– the biofiltration system harnesses the natural treatment action of vegetation and the filtration power of specially engineered soils
