Masterplan Grube Reden

The master plan developed by Vista for transforming the former “’Grube Reden’” coal mine forms the basis for a wide range of new functions. Inspired by the special architecture and specific landscape characteristics of mining, an ambiance was created that attracts various cultural and economic activities. 

The most important sub-areas are as follows: the campus with new businesses and cultural facilities, the water garden on the former switchyard that serves as a receptacle for rainwater and cools warm mine water before it is returned to the larger water system, and the former silt basin that is transformed into a natural lake which will function as a water buffer with an adjacent forest for the production of bamboo and biomass.

The former switchyard of the old “Grube Reden” mine will be transformed into a 750-meter long water garden. The basins cover the highly polluted ground and collect the rainwater of the entire campus. 

Various ecosystems are planned for the the garden. The design includes low-dynamic rainwater basins and fluctuating peak storage basins. In addition, a part of the garden is supplied with warm mine water from the geothermal power plant. The garden features two squares, several play areas and a 50-meter long canyon. Wide footpaths run in between the basins. A 9-meter high gabion wall forms the transition between the water garden and the campus.

In de tuin zijn verschillende ecosystemen te onderscheiden: Laagdynamische regenwaterbassins en fluctuerende piekbergingsbassins. Daarnaast wordt een deel van de tuin gevoed met warm mijnwater van de geothermiecentrale.

In de tuin bevinden zich twee pleinen, meerdere speelplekken en een canyon met een lengte van 50 meter. Brede wandelpaden lopen, deels verdiept, tussen de bassins door. Een negen meter hoge schanskorvenmuur vormt de overgang tussen de watertuin en de campus.
