Journey through time
Stages of a varied history – through use and intervention by humans, the Lippe was changed from a natural lowland river with watermeadow landscapes, meanders and oxbow lakes into a concrete-lined waterway. It was straightened, shortened, reinforced, dyked up and polluted. And now, as the next stage, comes the restructuring into an ecologically enhanced, near-natural river landscape – no easy task! Experience the development of the Lippe step by step in a virtual journey through time.
The Lippe at Lünen before the dyke was built
On 19 January, the Prussian Parliament of the day passed the LIPPEVERBAND Act. The LIPPEVERBAND was thus founded. The catchment area of the upper section of the Lippe has an entirely different water management situation, and thus does not belong to the association district.
Soest wastewater treatment plant
In Soest, the first wastewater treatment plant built by the LIPPEVERBAND goes operational. The wastewater treatment already takes place with biological methods, using trickling filters.
Waterbody maintenance becomes the task of the association
Alongside the traditional water management tasks – and especially wastewater treatment, ensuring drainage and flood protection – the amendment of the water association legislation also transfers the maintenance of the Lippe and its banks to the LIPPEVERBAND.
Lippe water for shipping canals
The exchange of water between the Lippe and the West German shipping canals is conclusively regulated. On this basis, the "Wasserverband Westdeutsche Kanäle" (Water Association of West German Canals) commences its work to ensure the water supply of the shipping canals and the enrichment of the Lippe.
Germany's tallest river dyke in Hamm
At 16 m, a Lippe dyke in Hamm-Herringen reaches previously unheard-of dimensions. Today, this dyke is even 17 m high, and is thus the highest river dyke in Germany.
Hasseler Mühlenbach after restoration
The Hasseler Mühlenbach is the first near-natural restructured stream of the LIPPEVERBAND.
Lippeverband region grows
The Lippeverband Act is updated, and now makes it possible to restructure the LIPPEVERBAND to correspond to modern requirements. Reserve spaces from the mining industry in Ahlen, Ascheberg, Drensteinfurt and Raesfeld are added to the association region. In the west, the LIPPEVERBAND region is expanded by the catchment areas of the Rotbach and Mommbach streams.
Water quality of the Lippe
For the first time, the water quality of the Lippe is consistently classified as satisfactory or good. By contrast, the water quality map of 1979 still showed the yellow colour for poor water quality in wide areas. Today the water quality is almost entirely good.
Subsidiary Lippe Wassertechnik
On 1 August, "Lippe Gesellschaft für Wassertechnik mbH" is founded, a private subsidiary of the LIPPEVERBAND, which can perform services in the field of water management for municipal administrations and companies, even outside the Lippeverband region.
Dortmund-Scharnhorst wastewater treatment plant
The Dortmund-Scharnhorst wastewater treatment plant becomes the first wastewater treatment plant to commence operation within the framework of the Seseke Programme. State-of-the-art wastewater treatment thus also finds its way into the Seseke region, and makes a significant contribution to reducing pollution of the Seseke and its tributaries. The LIPPEVERBAND is progressively converting these from open wastewater channels into clean waterways.
The youngest wastewater treatment plants
With the wastewater treatment plants at Hamm-West (right) and Kamen-Körnebach (left), two large, newly built plants belonging to the association commence operation.
The LIPPEVERBAND turns 75
The LIPPEVERBAND turned 75, and celebrated its jubilee with a ceremony on 19 January in Lünen. The keynote speakers were Bernd Tönjes (Chairman of the Association Council and Chairman of the Executive Board at DSK), State Secretary Christiane Friedrich (NRW Ministry of the Environment), Mayor Hans Wilhelm Stodollick, and Dr Jochen Stemplewski (Chairman of the Executive Board at the LIPPEVERBAND).
Seseke is sewage-free
The commissioning of the modernised wastewater treatment plant at Lünen-Sesekemündung, which at 200,000 PE is the largest operated by the LIPPEVERBAND, was the last stage in equipping the Seseke area with a future-oriented wastewater management infrastructure. Four new wastewater treatment plants, around 70 km of sewers, and around 90,000 m³ of stormwater treatment plants, ensure that sewage will no longer be drained through the Seseke and its subsidiary waterways!
Körne is ecologically enhanced
The Körnebach stream was once a tranquil waterway, with its source in the north of Dortmund, and flowing into the Seseke in Kamen. Later, from the 1920s onwards, it served as an open wastewater channel for 80 years, and was lined with concrete base plates and banished behind barbed wire fences. Today, after the LIPPEVERBAND invested around 85 million euros in the construction of sewers and the ecological improvement, the Körnebach has been reborn as "the Körne", and is once again an attractive waterway with a cycle path 11 km long.
In Hamm – Wastewater disposal and cleaning from a single supplier
In 2007, the tasks of municipal drainage in Hamm, which had previously been performed by the City of Hamm itself, were taken over by the LIPPEVERBAND: three wastewater treatment plants, numerous stormwater treatment plants, and around 750 km of sewer system are now operated by a single supplier, the LIPPEVERBAND. The takeover of a municipal sewer system allows cost optimisations to be expected, which will ultimately benefit the residents.
Relocation of the Lippe mouth section
On behalf of the NRW Ministry of the Environment, the LIPPEVERBAND moves the mouth of the Lippe around 250 metres to the south near Wesel, . This is necessary, because a new road is planned in the area of the mouth of the Lippe in order to improve transportation infrastructure. The relocation of the mouth of the river creates new opportunities for the Lippe and its surroundings.
