Herkules rainwater tank

  • 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.
  • Awarded product of the year by the German Trade Association for Plastics Processing (FKVV)
  • Fast connection (assembly is effected without screws)
  • Long life due to solid profile packing (lifetime proven over 25 years in laboratory tests)
  • Can be extended as required. Volumes of several 1,000 l are possible using preformed connections and connection points
  • Easy to transport due to low weight and practical size


  • For rainwater harvesting in house and garden
  • For frost-proof installation in the ground (not suitable for vehicle loading) or overground installation in the garden or cellar (fits through every standard door ≥ 80 cm)
  • Can be installed in groundwater and stratum water up to the top edge of the tank with an earth covering of at least 80 cm
