Stadtentwässerung Hannover

What Stadtentwässerung Hannover does

Stadtentwässerung Hannover (SEH) is the municipal wastewater and drainage utility of the Landeshauptstadt Hannover, organized as an Eigenbetrieb under Dezernat V (Economics and Environment). Founded in 1896 and headquartered in Hannover, Niedersachsen, the utility provides mandatory wastewater collection, treatment, and stormwater management services to all residents and businesses of Hannover and surrounding municipalities. Service is delivered through direct municipal infrastructure, supported by a 24-hour emergency hotline (0511 168-47377) and operational field teams.

The core technical asset is the Klärwerksverbund Hannover, an integrated treatment plant association that combines the Herrenhausen and Gümmerwald facilities into a coordinated wastewater treatment system. The broader service portfolio spans canal construction (Kanalbau), canal cleaning and rehabilitation (Kanalreinigung und -sanierung), property drainage (Grundstücksentwässerung), flood protection (Hochwasserschutz), heavy-rain advisory (Starkregenauskunft Hannover), and public toilet management (Öffentliche Toiletten). The utility also runs apprenticeship programs in environmental technology, industrial mechanics, and electronics, and provides visitor tours of its facilities.

Revenue is generated through mandatory fees, contributions, and charges (Gebühren, Beiträge, Entgelte) on a recurring basis, tied to water consumption and property characteristics. As a municipal Eigenbetrieb, SEH is wholly owned by the City of Hannover with no private shareholders; it is not publicly traded and does not raise external funding. The organization is governed under public law and is overseen by the city's Wirtschafts- und Umweltdezernentin. Distribution is direct-to-customer via the municipal sewer network, with public-facing communication handled primarily through the official Hannover.de portal.
