Downpours bring joy
When the sun shines down from the sky again with all its strength it makes the sun worshipper happy. Yet without regular watering, no plants can survive a hot summer. Watering your garden from the public drinking water network is an expensive pleasure, which can quickly add a couple of hundred euros to your water bill. Using the chilled water for toilets and the washing machine puts a strain on your wallet inside the hours too: just a fraction of the water used daily actually needs to be of “drinking” quality.
This would mean that you need not watch every penny when it comes to water consumption. Nature provides us with enough free rainwater, captured and stored in appropriate underground tanks, to supply our gardens.
Products for every need
As a specialist in harvesting rainwater, the Otto Graf company supplies everything you need for efficient water saving. The market leader in rainwater harvesting has more than 40 years experience in this sector and has designed a clever modular system around the Carat underground tank. An individual solution can be tailored to the needs and wishes of the customer from the four building blocks, the Carat underground tank, tank cover, tank extension and pump packages. These different complete packages are offered for retrofitting of outside areas up to professional variations for household use. Naturally, this includes top quality, self-cleaning filter technology.
The movable tank dome of the Carat facilitates easy adjustment to the position of the pipe system. Graf guarantees the Carat underground tank for 25 years as a particular security for customers.
Cost reduction through active environmental protection
It is so easy to reduce domestic drinking water consumption by more than a half and, thereby, to see a tangible reduction in your living costs. This cost saving does not just please your wallet.
