Stadtentwässerungsbetrieb Paderborn (STEB)

What Stadtentwässerungsbetrieb Paderborn (STEB) does

Stadtentwässerungsbetrieb Paderborn (STEB) is a municipal drainage and wastewater utility wholly owned and operated by the City of Paderborn in North Rhine-Westphalia, Germany. The organization holds statutory responsibility for public sewage collection, wastewater treatment, and canal network management within Paderborn's city area. STEB maintains a canal infrastructure spanning more than 1,000 kilometers across multiple city districts including Elsen, Marienloh, Dahl, Wewer, Schloß Neuhaus, Sennelager, and the city center, and operates a single central wastewater treatment plant. Its primary customers are residential property owners requiring drainage services, sewage connections, backflow protection, and stormwater management, alongside commercial and industrial establishments needing specialized wastewater advisory services.

The utility's technology stack centers on a digital Kanalkataster (canal cadastre) that digitally records all mixed water, rainwater, and sewage canals for operational reference and public inquiry. STEB also operates the Auskunfts- und Informationssystem Starkregen (AIS), an interactive heavy rain hazard mapping system visualizing flood extents, depths, flow velocities, and flow directions at varying rainfall intensities, developed in partnership with Dr. Pecher AG. Canal rehabilitation is performed using trenchless methods including robot-assisted repair and cured-in-place pipe lining (Schlauchrelining) to minimize surface disruption. A notable infrastructure innovation is the installation of a heat exchanger in the sewage canal along Münsterstraße, planned to recover thermal energy from wastewater for heating the administrative building at Hoppenhof from winter 2027/28.

STEB operates as a direct-to-customer municipal utility with no intermediaries or resellers. Services are delivered through in-person consultation at its headquarters on Bentfelder Strasse 12 in Paderborn-Sande, a central service line, a 24/7 emergency hotline for operational disturbances, and online self-service portals providing access to the digital canal cadastre and flood hazard information. Revenue is generated through regulated municipal utility fees and charges levied on property owners under German municipal utility regulations, billed based on usage and property characteristics. The organization employs approximately 23 staff and is actively recruiting apprentices for 2027.
