The advantages of below ground SUDS solutions:

• Low space utilisation
• No health and safety risk
• Adaptability to suit site conditions
• Low vandalism risk
• Low maintenance

Compared with the more traditional methods of creating underground stormwater storage, such as concrete rings or large diameter pipe sections, modular cells offer some distinct advantages.

• Geocellular units are exceptionally easy to handle on site, allowing rapid construction of the tank
• The modular format allows flexibility in the design of the tank plan area or depth to suit available space or to accommodate a high water table
• Cubic or rectangular tank volumes minimises the amount of excavated spoil and simplifies the backfilling process
• Typical porosity ratios of 96% minimise the extent of the excavation for any given tank volume.
