Stormwater Infiltration/Recharge
StormPrism stormwater infiltration systems provide a complete recharge solution. StormPrism can be configured to allow captured stormwater to infiltrate into underlying soil layers to recharge groundwater which achieves a best practice goal set forth by the U.S. EPA as a best management practice. StormPrism can also be configured to allow stormwater to percolate into “sand beds” to act as filtration and, StormPrism can be configured to access open graded bedding to increase storage volumes. In each case StormPrism can be configured with internal filters to trap sediment and debris before it enters the underlying soils. Pretreatment is also available utilizing standalone stormwater treatment devices. StormPrism belowground stormwater harvesting systems provide a complete solution for the process of allowing stormwater runoff to permeate into the ground, offers numerous environmental and urban infrastructure benefits. This natural process is crucial for maintaining groundwater levels and reducing the negative impacts of urbanization on water cycles.
INFILTRATION
Recharging Ground Water
Stormwater infiltration plays a vital role in sustainable water management by replenishing groundwater supplies, mitigating flood risks, improving water quality, and supporting healthy ecosystems. StormPrism underground infiltration solutions provide a stormwater management technique designed to manage and treat stormwater runoff by allowing it to percolate into the ground, mimicking natural infiltration processes that are often disrupted in urbanized areas.
How Infiltration Works
- Collection: Stormwater is directed into the StormPrism underground system through a network of dre and pipes.
- Temporary Storage: The StormPrism system temporarily stores the stormwater, providing immediate relief to the stormwater system during peak flow conditions and preventing immediate runoff into water bodies or overburdened sewer systems.
- Infiltration: The bottom of the StormPrism system will allow water to slowly infiltrate into the surrounding soil.
- Treatment: As stormwater infiltrates through the soil, it undergoes natural filtration, which helps remove pollutants, sediments, and other contaminants, improving water quality.
Primary Benefits of Stormwater Infiltration
- Groundwater Recharge: infiltration replenishes aquifers, which are critical sources of freshwater for drinking, agriculture, and industry. This is especially important in areas facing water scarcity.
- Flood Mitigation: By promoting the capture and absorption of stormwater into the ground, infiltration reduces the volume of water flowing into storm drains and waterways, thereby decreasing the risk and severity of urban flooding.
- Pollution Reduction: Infiltration can naturally filter stormwater, removing pollutants such as sediments, nutrients, metals, and other contaminants. This process helps improve the quality of groundwater and surface waters.
- Erosion Control: Reducing the speed and volume of surface runoff helps prevent erosion in waterways and landscapes caused by the force of moving water.
- Protecting Waterways: By decreasing runoff and filtering pollutants, infiltration helps protect rivers, lakes, and streams from pollution and the negative effects of sudden increases in water volume, preserving, aquatic ecosystems.
Configurations
Every site requiring stormwater management has its unique features whether it be the site topography, runoff quantity, compact site geometry or existing structures can create significant challenges to configuring and underground detention system. StormPrism layouts are endless.
treatment
“The first line of defense for treated captured stormwater is the inclusion of a forebay at the inlet of the stormdrain into the StormPrism detention system. This forebay creates an area that allows sediment from the “first flush” to settle out prior to entering the main stormwater collection chamber. Sediment is then more easily removed from the system during maintenance operations.
Maintenance
StormPrism stormwater management solutions are designed and engineered to allow for full system equipment access. This allows for maintenance equipment to enter and navigate within the system for cleanout and maintenance as required.
Groundwater recharge
Infiltration replenishes aquifers, which are critical sources of freshwater for drinking, agriculture, and industry. This is especially important in areas facing water scarcity.
