This new underground stormwater detention system creates a large storage chamber utilizing geosynthetics, stone and concrete slabs. The system offers a cost effective alternative to traditional underground stormwater detention and retention systems and requires a smaller footprint. The chamber allows for the easy access that is so important for maintaining the system.

Project Advantages of GeoStorage include:

• Material and Installation Cost: Installs faster and provides substantial savings.
• Size: Requires smaller footprint than traditional systems.
• Durability: Constructed with a reinforced concrete roof, stone and durable geosynthetics.
• Stormwater Quality: Allows for cost effective inclusion of a water quality structure within the system and doesn’t increase metal loading in stormwater.
• Maintenance: Large open chambers allow for easy access and maintenance.
• Load Capacity: Designed for a HS-20 highway loading.
