Stormwater Storage Below Ground
Underground Stormwater Tanks
Modular underground systems for detention, infiltration and rainwater harvesting, designed to integrate stormwater storage within constrained urban and development sites
Atlantis underground stormwater systems provide modular below-ground storage solutions for detention, infiltration and rainwater harvesting applications. By locating stormwater storage beneath the surface, these systems help preserve valuable land for buildings, roads, landscaped areas, public spaces and other functional uses while integrating water management within the broader site design.
Their modular configuration allows storage capacity and system geometry to respond to project-specific requirements, including available footprint, required storage volume, site constraints and loading conditions. This flexibility enables underground storage to be incorporated across commercial developments, infrastructure projects, landscaped environments and complex urban sites where efficient use of space is an important consideration.
System selection and configuration should respond to the hydraulic objectives of the project, available footprint, cover and loading conditions, groundwater considerations, site characteristics and requirements for access and maintenance. These factors help determine the most appropriate approach for detention, infiltration or rainwater harvesting within the overall stormwater management strategy.
One System, Different Stormwater Strategies
Underground storage can be configured to respond to different stormwater management objectives, from controlling peak discharge to infiltration and water reuse
Detention
Temporarily stores stormwater and releases it at a controlled rate
Note: Atlantis does not endorse detention systems. Detention systems discharge “recyclable” water into existing storm water systems where the water is contaminated causing heavy pollution downstream.
Infiltration
Provides temporary storage while allowing stormwater to infiltrate into suitable surrounding soils
Rainwater Harvesting
Stores captured rainwater for suitable non-potable reuse applications
Approved for POTABLE WATER
