Introduction Company profile and strategyService portfolio Communication and social responsibilityResource stewardshipOutstanding water qualityMunich Airport sources its potable water from Moosrainwater utility company, which extracts it from sixbore holes at depths of between 94 and 160 meters.The bore holes are located in source water protectionareas at Obere Point and Oberdingermoos in the Ober -ding municipality. The water is subject to strict monitoringand controls, and is of the highest quality. Atpresent we do not use any rainwater as service waterin our facilities.Protecting drinking water resourcesUntil recently, our trigeneration plant at Munich Airportneeded around 170,000 cubic meters of potable watera year to cool its chillers and generator sets. Becausethis water is extracted from tertiary strata and is a valuableand scarce commodity, the local water authoritieshave stipulated that water used for closed-circuit cool -ing must now be drawn from quaternary strata closerto the surface. To comply with this requirement we in2010 drilled a bore hole close to the airport’s energycenter from which we now extract quaternary ground -water to supply the energy center. Since this solutionwas implemented, the center has not used any potablewater for cooling.Analysis of rainwaterWe check the quality of rainwater at Munich Airportby testing 13 individual and aggregate parameters.There are no binding guidelines as such when itcomes to assessing rainwater quality. However, becauserainwater drains into the ground and becausedrinking water is often extracted from the groundwater,we take Germany’s most recent Drinking WaterOrdinance as a guide. In 2011, rainwater tests atMunich Airport showed that, with the exception ofa few pH values that were too low, all of the parameterswere within the limits set by the Ordinance.Wastewater treatmentAircraft need to be washed at regular intervals. Thisis not just for safety reasons, but also because dirtaccumulating on the skin causes drag and increasesfuel consumption. The wastewater from aircraft wash -ing contains detergent residue, oil, kerosene andheavy metals. The water is fed from our three maintenancehangars through a network of pipes to ourown wash-water treatment plant. Once cleaned andprocessed, the water is tested for quality, given afinal check and then fed into the sewage system. Wetest the water regularly to ensure that the residualpollutant levels are within the statutory limits definedfor wastewater.Total fresh water consumption 1Liters per workload unitTotal wastewater discharge 1, 2Liters per workload unit26.825.622.263.959.955.72009 2010 20112009 2010 20111Includes all companies on campus2Wastewater discharged to treatment facility comprises domestic wastewater,deicing water and rainwater.102
Workforce and work environmentEnvironmental and climate protectionP Climate strategyq Resource stewardshipp Noise controlp BiodiversityFinancial reviewSustainable developmentAll of the airport’s wastewater, including meltwatercontaining deicing agent that drains off our runwaysand aprons in winter, is treated at a processing facilityin nearby Eitting, operated by the local Erdinger Moossewage company and specially expanded with theairport’s support. Rainwater runoff from runways inthe summer is relatively clean and can be allowed todrain laterally off paved areas; some goes into the livetopsoil, and some flows via depressions in the terraininto drainage ditches.Deicer recyclingAt Munich Airport, most aircraft ) deicing is carriedout by mobile deicing units at specially designatedareas close to the runway heads. These areas areequipped with a system to trap wastewater from de -icing operations and channel it into underground storagetanks. There the water is cleaned mechanically andchemically, then distilled and turned back into deicingfluid by means of additives. This process of recyclingenabled us to treat and reuse 65 percent of the deicingfluid used during the 2010–2011 winter.Waste avoidance, recycling and disposalThe primary goal of waste management is to avoidgenerating waste. Under our in-house procurementguidelines, products that we as an organization purchasemust satisfy environmental as well as economicrequirements, and should be as eco-friendly as possible,with a long service life.Waste reduction and recycling, too, are important,alongside waste avoidance. Only waste that cannotbe recycled or processed for energy recovery is sentfor permanent, environmentally compatible disposal.A basic requirement in recycling is to strictly separaterecoverable fractions from waste. To accomplish this,we have six waste collection points on campus wherespecially trained staff extract and sort the various materialsand have them collected for processing by certifiedwaste transport and disposal operators. We alsooptimize waste logistics – by maximizing containerloads and keeping transport distances as short as wecan so as to avoid harmful emissions like CO 2 .) Glossary103
