 The Wuhletal is a green corridor in the northeastern Berlin district of Marzahn-Hellersdorf on the River Wuhle, from which it also has its name.The park was established after the decommissioning of the Falkenberg sewage treatment plant from 2002, which had previously used the Wuhle as receiving water.The closure of the sewage treatment plant was considered critical by environmentalists because of the expected fall in the groundwater level in the landscape park area.
