2014 Compact

The operation of a large airport results in high water requirements as well as a large quantity of wastewater. When handling the precious commodity of water, Fraport observes all aspects of modern water management. This concerns not only water consumption but also the quality of the water that is introduced into the ecosystem via the airport area. Using over 550 groundwater measurement points at Frankfurt Airport and in its immediate vicinity, we monitor the quality of the groundwater and ensure compliance with prescribed threshold levels in conjunction with the authorities. The drinking and service water network at Frankfurt Airport is 130 kilometers in length in total. Drinking water is sourced from the Hinkelstein well system, located around 3 kilo- meters to the north of the airport. We acquire service water from rainwater treatment facili- ties in CargoCity South, in Terminal 2, as well as at Pier A-plus, in addition to from our own groundwater wells and treated water from the Main River. We use it in sprinkler systems, toilet flushing systems, and to irrigate green areas. The service water supply system in CargoCity South has been extensively expanded. In the north, Terminal 2 is already supplied with service water, while 70 % of Terminal 1 and the neighboring office buildings have access to this supply. Comprehensive supply to all areas is planned to be finished by 2016. We do not merely want to replace drinking water with service water, but also use water in a fundamentally frugal way. The greatest savings achieved to date have been consistent use of water-saving techniques in wash basin fittings and toilet flushing. In technical areas, water is saved through methods such as the use of circulation systems in vehicle washing systems. 300 kilometers of channels for sewage and rainwater Fraport operates 2 separate sewer systems for wastewater and rainwater. This allows us to avoid the overloading of water-treatment plants in the event of heavy rainfall. The waste water system has a sewer length of approxi- mately 100 kilometers and contains wastewa- ter from toilet facilities, canteens, restaurants, vehicle washing systems, plane toilets, and water used to clean aircraft. Wastewater from the northern section of the airport is puri- fied in the water-treatment plants in Frank- furt-Sindlingen and Frankfurt-Niederrad. In the southern section of the airport, Fraport operates its own water-treatment plant. A further 200 kilometers of sewers collect the rainwater from the apron, aircraft positions, de-icing pads, roads, parking spaces, and roofs, for example. It flows through a number of safety facilities and filer systems and is then led into the Main River, the Gundbach River, or infiltration systems. Use rainwater, save groundwater Over the past 14 years, the proportion of service water in Fraport AG’s overall water consumption at Frankfurt Airport increased from 11 % to 24 % in 2014, and in 2011 and 2013 to as high as 25 %. 452014 Compact Responsible Corporate Management
