Heineken's brewery on the Bahamas uses seawater, which is purified to drinking-water quality. Water quality and availability are issues which receive our constant attention. Every two years, a survey is carried out to assess the quality and vulner ability of our water sources. This involves analysing all of the chemical parameters and comparing them with international drinking-water guidelines such as those published by the European Union and the World Health Organisation. Although the 2003 survey showed that, in some locations, the incoming water was contaminated with heavy metals and/or solvents, even in these cases Heineken's water-treatment processes were able to raise the water to drinking- water quality in accordance with the applicable quality standards. The survey showed that water availability had not changed since the previous sur vey in 2001. At Heineken's request, a study was Specific water consumption for soft-drink production decreased to 3.3 hectolitres per hectolitre of soft drinks, mainly due to the physical separation of the beer and soft-drink production units at Skopje and reduced operation of the C02 generator, and hence reduced usage of water for cooling and cleaning, at our plant in Kinshasa (Democratic Republic of Congo). Water sources The production units draw most of the water they use from the public utility supply or their own boreholes. Shanghai Asia Pacific Breweries Reducing water consumption In 1999, Shanghai Asia Pacific Breweries in China was using more than 9 litres of water to brew one litre of beer. By replacing its underground piping system, using basic waste water to remove sulphur dioxide from flue gas, introducing computerised man agement of its waste-water treatment plant and adopting a numberof simple practical measures, the brewery has cut its consumption by 40 per cent, while beer production has risen by a similar percentage. Water sources ZHOU ZHI HUA PUBLIC UTILITY GROUNDWATER SURFACE WATER carried out by Prof. Dr. E.K. Duursma, Emeritus Professor at Groningen University, to relate our breweries' water consumption to rainfall within their catchment areas. This resulted in the development of a method for determining the hydrological footprint of each brewery and predicting water availability. Waste water The water used as a consumable by our operating companies is ultimately discharged as waste water. Waste water from 68 per cent of our production units is treated, either in their own on-site plants or in municipal plants. Waste water from the other produc tion units is discharged untreated into surface water. Heineken has embarked on a programme to build HEINEKEN N.V. S U S T A I N A B I L I T Y REPORT 2002-2003 32
