Stormwater Harvesting/Reuse
StormPrism belowground stormwater harvesting systems provide a complete solution for collecting, storing, and reusing runoff water, typically from urban areas. ‘Stormprism is designed to capture stormwater that would ctherwise flow into drainage systems and possibly lead to pollution or flooding. Once collected, the stormwater can be treated as necessary and then repurposed for various ‘non-potable uses, such as irrigation, landscape watering, industrial processes, toilet flushing, or even for replenishing groundwater supplies, depending on the level of treatment it undergoes.

Harvesting & Reuse of Stormwater Runoff
‘Stormwater harvesting presents a valuable strategy for sustainable urban water management, aligning with broader goals of resilience and environmental stewardship. Implementing stormwater harvesting using ‘StormPrism underground systems requires careful planning to address challenges such as initial investment costs, ongoing maintenance, ensuring water quality for intended uses, and integrating the system with existing urban infrastructure.
Primary Benefits of Stormwater Harvesting
- Cost Savings: For municipalities and property owners, using harvested stormwater for non-potable applications can offer significant savings on water bills and contribute to sustainable water management practices.
- Reduces Flooding: Capturing stormwater can mitigate urban flooding by reducing runoff volume and peak flow rates.
- Water Conservation: Harvesting stormwater reduces dependence on traditional water supplies, conserving valuable freshwater resources.
- Promotes Sustainable Practices: Integrating stormwater harvesting into urban planning encourages sustainable development and the use of natural resources in a more balanced manner.
- Mitigates Urban Heat Island Effect: Green infrastructure associated with stormwater harvesting, like green roofs and vegetated swales, can help cool urban areas by providing shade and evapotranspiration.
Key Components of the System
- Collection: Stormwater is collected from surfaces like roofs, parking lots, roads, and other impervious areas where it would usually run off.
- Storage: The concrete vault serves as a reservoir for the collected stormwater. Vaults are engineered to handle significant volumes and are often modular, allowing for customized capacity based on the anticipated runoff and intended use of the harvested water.
- Treatment: Before reuse, stored stormwater may undergo various treatment processes to meet safety and quality standards for its intended use. This can range from basic filtration to more advanced treatment methods.
- Distribution: Once treated, the water can be distributed for non-potable applications. Systems for distribution will vary based on the specific needs and infrastructure of the area or facility using the harvested stormwater.
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.
