With 33 per cent and 29 per cent of total water consumption, sanitary facilities and production accounted for by far the largest share of total water consumption. The remainder is accounted for by cooling with evaporative cooling systems (21 per cent) and some subordinate processes such as the irrigation of green areas and canteen operation. The weighting between uses changed compared to the previous year. While there were savings in production, consumption in the other areas increased mainly due to the warm weather in Europe and the renewed increase in the number of employees at work. GRI 303-5 Measures are being implemented in all areas to continuously reduce consumption. Our own buildings are equipped with water-saving fittings throughout. Wherever possible, we optimise the production processes that generate wastewater and reuse the wastewater for other purposes. In 2021, an evaporative cooling system was replaced with a hybrid cooler with minimal water consumption as part of the conversion of the cooling provision at the company headquarters. This saves between 3,000 and 4,000 cubic metres of water every year. No further significant water-saving measures were identified and implemented in the current reporting year. The illustration on the right shows the water intake by source over the years 2020 to 2022. Approximately 98 per cent of the water consumption is covered by the public water distribution. Just over 2 per cent of our water consumption come from our own groundwater wells, which are used exclusively to irrigate the green areas. GRI 303-1, GRI 303-3 Wastewater Polluted wastewater is discharged exclusively into the public sewer system. Our production wastewater is treated for process-specific pollutants before it is discharged. We hold the necessary permits for all treatment plants and monitor the treatment and pollutant parameters. With the exception of unpolluted rainwater, we do not discharge any wastewater into natural waters or groundwater. The illustration on the right shows the wastewater discharge by quality and discharge location over the years 2020 to 2022. The development and distribution across the categories is explained by the type of water use described above. 303-1, GRI 303-4, GRI 306-1, GRI 306-5 * In the Sustainability Report 2021, the values for the categories values for production and sanitary wastewater were incorrectly assigned. The value for sanitary wastewater in 2021 was corrected due to a subsequent notification by a plant. 72 73 Festo SE & Co. KG Sustainability Report 2022 Festo SE & Co. KG Sustainability Report 2022 1.
