A bio-retention cell is an area that usually contains backfill which is porous under a surface that is vegetated. Such arestoas are underdrained as a way of encouraging infiltration and filtration. These cells provide runoff retention, pollutant removal, and groundwater recharge and are useful in parking lots and urban areas.
How to enhance stormwater management in your home
Elimination of curb and gutter
Curbs and gutter transport flow very fast to your stormwater drain without even allowing infiltration by the inlet filter or pollutant removal. If you eliminate these, you can reduce the runoff volumes and raise the sheet flow. This way you help retain the hydraulic conditions and prevent soil erosion that would have otherwise resulted from stormwater. You can include a level spreader to ensure sheet flow and uniform water distribution.
Grassed swales
These are shallow outlets which are covered with grass for slowing down runoff and instead facilitating infiltration. These swales are sustainable depending on the land use, the slope, soil type and the dimension system of the swale. They are useful in maintaining from drainage runoff where the area is not more than four hectares. It is advisable to use low-lying natural areas and utilize natural drainage courses.
Green parking design
When green parking design is applied, the impervious contribution of your parking lots is reduced. These techniques include utilizing space pavers, using bio-retention areas in stormwater treatment, minimizing your parking lot dimension and using structured parking incentives.
Inlet protection devices
Also called hydrodynamic separators, these structures are flow-through with setting units for oil removal, greasing, and trashing. This technology is useful for pre-treating other devices that protect the inlet. Potential stormwater areas with high concentration are the most suitable areas for this.
Permeable pavement
These are good at promoting recharge of groundwater. Sound pavements create voids on corners of your pavers. You can use concrete grid pavers that comprise concrete blocks that can be utilized for forming voids in the block by clearing fine particles inside them.
Infiltration trenches
These are trenches 
filled with rock and have no channel. They collect runoff in the event of a storm and infiltrates it into the soil. They can be used alongside other infiltration devices that have inlet filters. This will allow for the attenuation of the flow.
These ways can help you enhance the management of stormwater at home to avoid erosion of the soil.
