Welcome!Working to keep our watersheds cleanThe Stormwater Equipment Manufacturers Association (SWEMA) is dedicated to the pursuit of clean water. SWEMA's mission is to: "Be the leader in advocating sustainable and effective solutions for stormwater quality through educational outreach to regulators, design professionals, developers and other stakeholders in clean water initiatives." Join SWEMA Today!The members of the Stormwater Equipment Manufacturers Association (SWEMA) invite you to become a member of this growing and dynamic association. The Stormwater Equipment Manufacturers Association is dedicated to being the leader in advocating sustainable and effective solutions for stormwater quality through educational outreach to regulators, design professionals, developers and other stakeholders in clean water initiatives. Our outreach in stormwater industry involvement is excellent and we welcome others to join our team. Join TodayWelcome to the New Stormwater Science SectionThis 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.
