A river breathes again
Until the end of the 19th century, the Seseke was a natural lowland river. But then mining and industrialisation developed in this region, and brought with them mining subsidence and flooding. In many locations, total inundations occurred. The Seseke became an open sewer for household and industrial wastewater. Because the construction of underground sewers was out of the question due to mining subsidence, the open disposal of wastewater in the Seseke was the only practicable solution. The waterways were deepened, and dyked up in areas of severe subsidence. When the mining industry withdrew from the region, the way was paved for new wastewater management solutions. The wastewater channel is being converted step by step into a near-natural waterway. Over the coming years, the Seseke and its subsidiary waterways will become wastewater-free and will be ecological improved.
Experience the stages of the transformation in the Seseke in a virtual journey through time.
Before industrialisation, the Seseke was a typical lowland river.
Mining begins in the Seseke area.
Mining subsidence leads to flooding: In many locations, total inundations occur.
The catastrophic conditions lead to the founding of the Sesekegenossenschaft water association.
The Sesekegenossenschaft is absorbed by the LIPPEVERBAND.
The mouth of the Seseke is relocated to outside Lünen.
The Kamen-Körnebach wastewater treatment plant commences operation.
The Lünen-Sesekemündung biological wastewater treatment plant commences operation.
The Seseke Programme is passed. The same year, the Braunebach, a subsidiary waterway of the Seseke, is freed from wastewater and renaturalised as a pilot project.
The first closed sewers are built on the Seseke in Kamen.
The Dortmund-Scharnhorst wastewater treatment plant becomes the first plant to commence operation within the framework of the Seseke Programme.
The separation process is completed, wastewater is collected and purified in a decentralised process, and waterways are being restructured to be near-natural.
The ecological improvement of the Körne, the largest subsidiary waterway of the Seseke, is concluded.
The groundbreaking for the ecological improvement of the main waterway of the Seseke introduces the final phase of the Seseke Programme - the restructuring of the main waterway of the Seseke begins.
The Seseke conversion is in full swing. Subdivided into four construction stages, the Seseke is converted into a living river. 71 kilometres of sewers have already been built. 55 kilometres of waterway have already been renaturalised on the subsidiary waterways of the Seseke.
