Designed from the ground upSay goodbye to ugly water tanks

Finally a system that offers all the advantages of a traditional water tank without taking up vital space in your backyard. the innovative Carat tank range by graF is specifically designed for storage underground, providing all the extra water you need, conveniently and economically.

With water restrictions here to stay, a Carat water harvesting system is the smartest way to ensure you always have enough water. Whether you require a little extra garden water or a water saving solution in the home for your toilet and laundry, the modular design of the Graf Carat system makes it easy.

The principle behind the Carat water harvesting system is simple. The collected rainwater from your roof is fed into the underground tank via a filtering system. The water is then delivered for use in and around your home via an electric pump. The pump can be either placed above ground or fixed in the tank.

The Carat water harvesting system is one of the most popular in the world today - and with good reason. Because the tanks are stored underground, the water is kept very cool, virtually eliminating the possibility of algal growth. So while you maintain the beauty of your outdoor environment, your Carat tank is maintaining the quality of your water.

Whether you’re a proud gardener or you just have a small outdoor area, the unique underground design of the Graf Carat enables you to completely eliminate the water tank from view. To ensure the integrity and long life of every tank, Graf utilises advanced production technologies and quality standards.

The unique two-piece design of the Carat range provides unbeatable strength and stability – all supported by a full 15 year warranty. What’s more, the profile sealings have been laboratory tested to last more than 25 years. Each tank is made from Duralen, a tough, high quality material that is extremely rigid and impact resistant. Aside from being light and easy to work with, Duralen is also recyclable, which is good for the environment.

Carat tanks can be assembled in only a few minutes without screws or bolts. The adjustable shaft ensures the lid can be made to sit flush with the ground, minimising visual impact. Besides the aesthetic advantages, Carat tanks can be installed just about anywhere, even under your driveway.
