Stormwater treatment involves removing pollutants from stormwater runoff using various techniques to improve water quality before it flows into receiving water bodies or is even reused for other purposes. Why is stormwater treatment needed? Climate change is changing the natural hydrological system with more frequent and intense rainfall predicted for the UK. Couple this with […]
The Hidden Sources of Pollution in Our Stormwater Systems When road pollution is discussed, attention usually focuses on vehicle emissions, tyre wear particles, brake dust and fuel leaks. While these are undoubtedly significant sources of contamination, they are not the only pollutants entering our rivers, lakes and oceans through stormwater runoff. The roads themselves, and […]
Permeable Pavement Systems (PPS) are one of the most widely used Sustainable Drainage Systems (SuDS) techniques in the UK. They are commonly incorporated into residential developments, car parks, public schemes and low-speed roads to reduce runoff volumes, provide source control and improve water quality. Unlike conventional (impermeable) pavements, PPS allow rainfall and surface water runoff […]
Understanding PAHs in Stormwater Runoff Stormwater runoff is a significant pathway for pollutant transport into receiving water bodies. Among these pollutants, Polycyclic Aromatic Hydrocarbons (PAHs) are a main concern in stormwater treatment, due to their persistence and toxicity in our environments. Particle Size Distribution (PSD) aids in determining how PAHs behave- in terms of their […]
