Philosophy
Otto Graf GmbH has been offering high-quality plastic products for 40 years. The company started out making plastic products for viticulture, such as wine barrels and harvest troughs. However, GRAF’s continual growth was also a result of the successfully sold composters and plastic containers for industry. Graf first developed products for rainwater harvesting in 1974 – a pioneering step at that time. Today, the majority of turnover comes from products connected to rainwater management.

Commitment to Germany as a location
GRAF is investing more than 20 million euros in a new production site at the company’s headquarters in Teningen near Freiburg (Baden). One of the most up-to-date production plants for plastic products anywhere in the world has emerged here on an area of 155,000 m2 – this corresponds to 31 football fields. Choosing Germany as the location was easy. On the one hand we feel an obligation to the site because of our history. On the other, we would like to offer our customers products of the highest quality. This is only possible with qualified and motivated employees. As a result, investment in a low wage country was never discussed.
Quality is at the forefront
What you need most to ensure consistent, high product quality are optimised production processes and outstanding quality management. Every individual tank at GRAF is checked with regard to dimensional accuracy, wall thickness and weight. All production parameters, e.g. material composition, all machine settings and also the staff involved in the production process, are documented for each individual product.
Our range: diverse and impressive
GRAF has 40 years’ experience of developing and producing extremely high quality plastic products. We are now the market leader in Germany and Europe for plastic rainwater collectors. Thanks to one of the largest ranges available on the market, we are in a position to offer you the right rainwater harvesting system for your needs.
Our strength: innovation and customer proximity
Our company is always open to new ideas and customer requests. These motivations flow directly into the development of new products. As a result, we are now one of the most innovative companies in the plastics industry. All components, e.g. filters, controls and naturally the tanks, are developed by our own development department. Today, six employees are responsible for the continued development of the Graf range. Our innovative edge is reflected in numerous patents, property rights and awards.
Polyethylene – clear advantages compared with concrete
Due to substantially lower weights, PE tanks up to 6,500 l volume can be installed without cranes; the associated costs fall. PE tanks impress because of their smooth inner and outer surfaces, which guarantees high water quality and easy cleaning.
Our employees: highly motivated and experienced
We now employ round about 250 people at our two locations at Teningen (Baden) and Dachstein (Alsace). Together we have more than tribled our turnover in the last 10 years and created over 100 new jobs – a success, which is the result of the know-how, commitment and performance of our employees.
Our goal: your satisfaction
More than 100,000 satisfied customers are already benefiting from the advantages of the GRAF product range. Let us convince you too!
