Separate Graf Platin Flat Tanks

The Graf flat tank has been specially developed for rainwater harvesting, and thanks to its shallow installation depth, it is a practical and viable option for retro-fit installation. Requiring less digging, it is therefore quicker and cheaper to install into many landscaping schemes. It comes with a 15-year warranty and being lightweight, it is easy to transport and move around. The ribbed design makes it light yet very strong and stable, enabling it to be installed in groundwater up to the shoulder of the tank.

The telescopic tank shafts slide up and down inside the dome, offering adjustment for height as well as up to 5° of tilt, making it easy to get the lid flush with ground level. They are available with a PE lid for pedestrian loading or a cast iron lid for vehicle loading. Fitting neatly inside the dome of the Flat Tank, the filter package has a removable filter basket for easy cleaning and incorporates an overflow siphon.
