Natural Absorption vs. Urban Runoff
What is Stormwater?
Stormwater is water from a storm. Any precipitation that falls from the sky, including rain, hail, and snow, is considered stormwater. There are two fates for stormwater:
- Absorbed in nature
- Runoff
Stormwater Treatment Process
Stormwater Wetlands
Stormwater Ponds
Stormwater treatment practices remove pollutants from stormwater!
Stormwater Ponds
Stormwater Wetlands
Stormwater Ponds
Pools of water enhance pollutant removal through mechanisms such as settling, plant uptake and decomposition.
Stormwater Wetlands
Stormwater Wetlands
Stormwater Wetlands
Man-made specifically for pollutant removal and flood control. Plants and organisms naturally filter the water.
Soil Infiltration
Soil Infiltration
Stormwater Wetlands
Pollutant removal occurs through water traveling through the air gaps in the soil.
Rain Gardens
Soil Infiltration
Rain Gardens
Capture, store, and filter stormwater through sand and soil. Like a plant filter!
Bioswales
Soil Infiltration
Rain Gardens
Reduce the speed of and stores stormwater runoff to encourage infiltration. They are the best for capturing metals and nutrients!
