Welcome to the New Stormwater Science  Section

This new section of the SWEMA website is your go-to source for the technical knowledge and science that underpins effective stormwater management. Each article in this section is crafted to illuminate how stormwater treatment technologies work, why they matter, and how they can be applied in the field. SWEMA's latest article "The Basics of Gravity Separation Devices," breaks down how gravity separation devices operate, the physical principles behind their design and their role in trapping sediments, oils and other pollutants before they reach sensitive water bodies.
