Rieselfelder Dortmund

from Wikipedia, the free encyclopedia

The Rieselfelder Dortmund , a landscape north of Dortmund , were originally sewage systems for waste water recycling in the city of Dortmund. The sewage fields are located in the Dahler Heide , a former heathland between Datteln , Waltrop and Lünen in the area of ​​the first two cities and thus in the Recklinghausen district .

In the middle of the 19th century, the discharge of untreated wastewater into the Emscher, which was not yet regulated at that time, turned out to be unsustainable. From 1883, the city of Dortmund built settling basins for primary clarification, which were supplemented by so-called Dortmund wells in 1887 . The construction of the sprinkler system by the city of Dortmund began in 1894 . In a considerable engineering effort, the 18 km long Rieselfeld Canal was completed within only 4 years. It was partially driven by mining at a depth of up to 24 m and crosses under the Emscher- Lippe watershed . After that, intensive agricultural use began in the area, mainly for growing vegetables. With the introduction of new wastewater disposal concepts, the irrigation of the areas ended in April 1978. The city of Dortmund sold the approx. 1000 hectare area to VEW , now RWE . This initially planned the construction of a large power plant on the basis of the State Development Plan VI (North Rhine-Westphalia), the first version of which provided 150 ha for coal-fired and nuclear power plants and 1700 ha for area-intensive large-scale projects in the Waltrop and Datteln urban areas. After public protests and due to overcapacity in the energy market, VEW withdrew from the "power plant" project in the early 1980s. The state government of North Rhine-Westphalia decided on July 14, 1985 to give up the Rieselfelder as a nuclear power plant location. In the early 1990s, an urban and ecological framework plan was drawn up by the Municipal Association of the Ruhr Area (KVR) in Essen, which was presented to the public on July 5, 1995. After 1997, the idea of ​​the "newPark" is pursued for the Rieselfelder, since July 17, 2003 exclusively in the city of Datteln, as the Waltrop city council rejected the implementation of the newPark concept.

The former sewage fields are still used primarily for agricultural and recreational purposes today. Together with the adjoining Lippeauen , the sewage fields represent an ecologically important habitat for numerous plant and animal species.
