Our History

Rainbow Waters® was founded in 1999 with headquarters in Acharnes Attica. Its object of activity was the provision of bottled watercoolers and distribution of the corresponding bottles (18.9 litres) in the wider Attica region. Realising the lack in sanitization and disinfection methods in the industry, we were the first to address the cooling machine (watercooler) and the corresponding bottle as food. Therefore, we looked for the best certified disinfection method, while we sought bottled water to meet the highest possible standards.

Thus, we concluded an exclusive cooperation relationship with Ebac Ltd, the English watercooler manufacturing firm, whose watercoolers, beyond their innovative design, were constructed with the consumer’s safety and health as a major priority.

In 2000, we launched an exclusive partnership with Zagori Bottled Water, whose quality perfectly matched the high standards we had set.

In 2001, following the wide acceptance from customers, we decided to expand to the rest of Greece. We created Zagori Rainbow Group SA based in Ioannina and through 4 branches and several representatives, we began to serve all of Greece.

In 2005, the company certified the management and quality systems that it implements according to the international standard ISO 9001: 2000 and ELOT 1416 (HACCP), by the international certification body BUREAU VERITAS. The company was the 1st company in Greece which had a certified quality system.

In 2008, our company was certified by NSF according to the European Bottled Watercooler Association (EBWA) standards, for the Athens store and Thessaloniki branch.

In 2009, realising the need for clean filtered water at home, we started an exclusive partnership with 3M, the leading American company, offering the ideal solution for any home with the certified 3ΜTM Home  Water Filters.

To 2014, using our long-term experience in the bottled watercooler industry and after many years of research in dozens of springs throughout Greece, we acquired our own spring and one of the most modern water bottling plants in Europe. Thus, with Dioni water we can now monitor and guarantee the quality of the bottled water from the spring and bottling network through to the storage, transport and distribution of the final product.

We remain the first company in the field with a quality system that is certified according to: ISO 9001:2008, ISO 22000:2005 (HACCP) and CAC/RCP 1-1969 (HACCP). 

Nowadays, the company is certified and holds 1st place in the industry, serving 315,000 satisfied customers since 1999. The Quality Management System that is implemented by Rainbow Waters® meets the requirements of international quality standards in terms of the distribution, disposal and sanitization of watercoolers, as well as the bottling and sale of bottled water.
