Because water is a key resource in producing beverages, Coca-Cola Hellenic makes protecting water sources and aquatic ecosystems a high priority. Most operations have projects underway for reducing water use, recovering water, or improving wastewater quality. The ratio of total water consumed to volume of produced beverage is defined as a water ratio and it represents one of the main environmental Key Performance Indicators. The average ratio for Coca-Cola Hellenic operations in 2005 was 2.89 liters per liter of produced beverage. The company's objective in 2006 is to reduce the average water ratio by 2%. The Danube Partnership The Danube River is one of Europe's most populated, precious and polluted waterways. Coca-Cola Hellenic, along with The Coca-Cola Company, has partnered with the International Commission for the Protection of the Danube River, and it participates in the Danube Day annual festivities to increase awareness of the Danube's value to communities. Sustainable water resources In another water-related program, Coca-Cola Hellenic's operations in Nigeria, The Nigerian Bottling Company, has installed potable water taps in nearby communities suffering from unreliable water supplies. This helps to combat poverty and disease, allowing villages to develop more sustainable water resources. Another initiative is to enable fish farming projects fed by treated wastewater from the company's bottling plants. This constant and abundant water supply allows local entrepreneurs to raise fish, providing a nutritious food source, as well as bringing in additional income to the local communities.
