history

At the beginning of the 20th century, three pumping stations were built in Bremen, which initially let the city's wastewater flow into the Weser without pre-treatment. In 1916 the first mechanical rough cleaning was installed.

Until 1990, the Office for Urban Drainage and Waste Management was responsible, among other things, for wastewater disposal in the city of Bremen. This office was converted into the Bremer Entsorgungsbetriebe - BEB for short, as an in-house operation. With the establishment of the hanseWasser Bremen GmbH, one company concentrated on urban drainage.

In addition to the wastewater from the Bremen sewer system, Hansewasser now also disposes of domestic and industrial wastewater from the municipalities of Lemwerder , Lilienthal , Ritterhude , Schwanewede , Stuhr and Weyhe as well as from parts of Oyten and Achim .

Sewage treatment plants

Hansewasser operates two sewage treatment plants to purify the wastewater:

The Seehausen sewage treatment plant purifies the wastewater of the city of Bremen - with the exception of the drainage area of ​​the Farge sewage treatment plant - and of the neighboring communities of Lilienthal, Ritterhude, Stuhr / Weyhe in Lower Saxony and partly Oyten and Achim. It is located on the left bank of the Weser. The wastewater from the connected drainage area to the right of the Weser is pumped there through culverts under the Weser. The daily output is 130,000 m³ of treated wastewater per day.

The sewage treatment plant in Farge is significantly smaller with an average capacity of 16,000 m³ per day. Here the wastewater from the districts of Blumenthal and Vegesack, the Burglesum district of St. Magnus (partially) and the neighboring communities of Lemwerder and Schwanewede are cleaned.

Hansewasser also manages the industrial wastewater treatment plants of Avangard Malz and AB InBev in their Bremen operations.

Ownership structure

Hansewasser GmbH is owned 25.1% by the Free Hanseatic City of Bremen and 74.9% by hVE (hanseWasser supply and disposal GmbH). This in turn belongs to 49% of Gelsenwasser AG and 51% of swb AG , a 100% subsidiary of EWE AG . The shares of these companies are not traded on the stock exchange and are predominantly owned by municipalities .
