Introduction Of Infiltration Basin
An infiltration basin is a percolation pond used to control stormwater runoff, avoid flooding and downstream erosion, and enhance the water quality of surrounding water channels. It is also known as recharge basin.
It is simply a small man-made pond that is intended to allow rainfall to permeate into the groundwater aquifer through permeable soils. Only infiltration, evaporation, or emergency overflow during flood conditions do infiltration basins release water.
Rapid Infiltration Basin
A rapid infiltration basin is a specific type of basin designed to treat and distribute municipal wastewater. Rapid Infiltration basins consist of permeable soil. These types of tanks are typically operated in conjunction with primary clarification ponds or primary and secondary clarification pond systems.
Infiltration Basin Design
To infiltrate the soil at a rate that won’t result in flooding, infiltration basins must be carefully planned. They might perform worse in places where:
- High volumes of groundwater nearby the intruding surface.
- Consolidated soils.
- High sediment content in stormwater.
- high soil clay content.
When the project also includes an extended detention basin as a pretreatment stage to remove silt, infiltration basins have proven successful at some sites. Where basins cannot be regularly maintained, they may fail.
Sum Up
Infiltration basin is different from the detention basin which is a empty pond and retention basin which designed to include a permanent pool of water.
