Potable Water Tanks

WRAS approved potable water tanks are provided using both the GRAF Platin and Carat underground tanks. Special requirements have to be met when storing potable water. Our Potable Water Tanks are made from robust, durable polyethylene. They are food grade-tested and easy to clean, thanks to their smooth inner surfaces, allowing potable water to be stored in a perfectly hygienic manner.

Water is our most precious resource. Not all homes can be connected with a mains water supply. Remote properties can use the water resources available to them in their local area. Fresh water from individual springs can be captured using spring shafts and fed to a potable water storage tank. The quality of the potable water is affected not only by the water itself – the components used to harvest and store it are key too. GRAF potable water storage tanks are only made from food-safe plastic. The smooth inner surfaces of the tank prevent dirt from sticking to them and they are easy to clean.
