The difference between above-ground and below-ground stormwater storage lies in their placement, construction, and use of space. Above-ground systems typically use tanks or lined ponds that are visible on the surface, making them easier to install, inspect, and maintain. These systems are often more cost-effective and suitable for sites with ample open space.
Below-ground systems, on the other hand, are built beneath the surface using tanks, vaults, or infiltration chambers. They are ideal for urban or developed areas where surface space is limited and aesthetics or land use must be preserved. While below-ground systems offer a more discreet solution, they can be more expensive to install and maintain due to excavation and structural requirements.
