Oil slick created by runoff A percolation trench allows infiltration of stormwater through permeable soils into the groundwater aquifer. An oil-grit separator is designed to capture settleable solids, oil and grease, debris and floatables in runoff from roads and parking lots. Excessive stream bank erosion may cause flooding and property damage.
Bioswales can be implemented in areas that require stormwater management to regulate the runoff velocity and decontaminate the runoff. Bioswales are created to handle the first flush of pollutants during the event of rain, therefore, locations that have high areas of impervious surface such as roads, parking lots, or rooftops can benefit from additions of bioswales.
Retention basin. A retention basin, sometimes called a retention pond, wet detention basin, or storm water management pond (SWMP), is an artificial pond with vegetation around the perimeter and a permanent pool of water in its design. [1][2][3] It is used to manage stormwater runoff, for protection against flooding, for erosion control, and to ...
Rain gardens, also called bioretention facilities, are one of a variety of practices designed to increase rain runoff reabsorption by the soil. They can also be used to treat polluted stormwater runoff. Rain gardens are designed landscape sites that reduce the flow rate, total quantity, and pollutant load of runoff from impervious urban areas ...
Bioretention. A bioretention cell, also called a rain garden, in the United States. It is designed to treat polluted stormwater runoff from an adjacent parking lot. Plants are in winter dormancy. Bioretention is the process in which contaminants and sedimentation are removed from stormwater runoff. The main objective of the bioretention cell is ...
t. e. Stormwater, also written storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil (infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff.
The state Department of Environmental Management approved a petition to force businesses in the Mashapaug watershed to address stormwater pollution. 'A major win for residents': How businesses ...
Bioswales, or other types of biofilters, can be created around the edges of parking lots to capture and treat stormwater runoff before releasing it to the watershed or storm sewer. Permeable pavement This section is an excerpt from Permeable paving .
