The National Decontamination Agency has engaged Tuttendorfer Breite, a joint venture partnering ALPINE Bau GmbH and Bilfinger Berger Bau GmbH, for the recovery of Tuttendorfer Breite, near Korneuburg, on a 21-million-euro budget. The recovery plan focuses on forestalling the spreading of pollutants and avoiding the pollution of groundwater by crude oil. Also included is ten years' control of the recovery plan. The necessary construction work has already begun, and it is estimated to be finished in mid-2009.

The polluted Tuttendorfer Breite area is the site of an old oil refinery built in 1927 and run by a number of companies until it was closed in 1961. A great deal of oil and petroleum products have soaked into the ground there. A funnel-and-filter system will be used for the site's recovery. The first step will be to cover the polluted area with 1,200 metres of impermeable walls, so as to prevent the release of environmentally hazardous emissions. A built-in active charcoal filter or "gate" will strain the hazardous substances out of the groundwater that seeps through the polluted zone. Wells will also be dug to extract oil and eliminate the crude oil film lying on the water.
