Name of eco-innovation demand Sustainable rainwater harvesting
and utilization system at the airport
Company / organisationBudapest Airport Zrt.
Description of required eco-innovation / solution / technology / resource / knowledge / product / serviceBudapest Airport Zrt. are looking for an environmentally friendly solution regarding the management and treatment of airport rainwater.
Background Budapest Airport has been developing its environmental performanc for years, where protection of groundwater and surface water is a key issue.

Airports are suitable for rainwater harvesting at a larger scale, because they have institutional and infrastructural advantages compared with cities.
Description of challenge to be solvedSeparate sanitary sewer systems have been built at the airport. Rainwater from the vicinity of Terminal 1 flows, via a gravity drainage system, into the water reservoir lake located at the airport, and is then pumped, via a pressurized sewer, into the gravity water drainage system operating at Terminal 2. From there, rainwater is channelled via a gravity conduit into canal number 171 and 17. Canal 17 flows into the Maglódi canal, which in turn is a tributary of the Gyáli creek. The problem recently is that the rainwater collected during winter time can contain differents pollutants from deicing acivities, namely urea and glycol.
