1.The Importance of Stormwater Filtration
Stormwater runoff isn't just plain water. As it travels across streets, parking lots, lawns, and 
rooftops, it picks up a variety of contaminants:
• Sediment: Soil erosion from construction sites, unpaved areas, and even our yards can 
wash away and cloud waterways.
• Oil and Grease: Leaking vehicles and industrial activities contribute oil and grease to 
stormwater runoff.
• Fertilizers and Pesticides: Excess lawn chemicals can end up in waterways, harming 
aquatic life and promoting unwanted algae growth.
• Debris: Litter, leaves, and yard waste can clog drains and pollute waterways.
These pollutants disrupt the delicate balance of our aquatic ecosystems, harming fish and 
plant life. They can also contaminate our drinking water sources, requiring expensive 
treatment processes. 
Stormwater filtration products act as a barrier, capturing these pollutants before they enter 
our waterways. Let's explore some of the most common types:
1.Types of Stormwater Filtration Products
2.Strainers and Grates: These are the first line of defense, capturing large debris like leaves, 
sticks, and trash before they enter the storm drain system. Filters can be installed at various 
points, including catch basins, gutters, and downspouts.
3.Sand Filters: These underground chambers filled with sand act as a natural filter. 
Stormwater runoff passes through the sand, allowing the sand to trap sediment and other 
pollutants. Sand filters require regular maintenance to remove accumulated particles.
4.Bioretention Swales: These landscaped channels mimic natural wetlands, using vegetation, 
soil, and a gravel underdrain to filter stormwater. Bioretention swales are aesthetically 
pleasing and provide additional benefits like habitat creation for pollinators.
5.Manufactured Treatment Devices (MTDs): These prefabricated units come in various designs 
and use different filtration media like sand, biofiltration media, or even oil-absorbing 
cartridges to capture pollutants. MTDs offer a compact and efficient solution for stormwater 
treatment in urban environments.
