- Multi-purpose – aboveground belowground and basements
- Aboveground: The Herkules Tank is easy to install in your garden. Combined with the established GRAF downpipe filters it’s a perfect way to harvest rainwater.
- Underground: Combined with the applicable accessories the Herkules Tank can also be installed underground. The tank is groundwater stable up to the top edge of the tank.
- Basement tank: Due to its size the Herkules Tank fits through a standard doorway (≥ 80 cm). Therefore it’s ideal for basement installation.
