Eigenbetrieb Stadtentwässerung Böblingen

What Eigenbetrieb Stadtentwässerung Böblingen does

Eigenbetrieb Stadtentwässerung Böblingen (SEBB) is a municipal wastewater utility wholly owned by the city of Böblingen in Baden-Württemberg, Germany, established in its current form on April 2, 2014, when it was spun out of the former Eigenbetrieb Stadtwerke Böblingen to focus exclusively on wastewater management. SEBB is responsible under German municipal law for the collection, treatment, and disposal of wastewater across the city of Böblingen and the district of Dagersheim. Its physical infrastructure comprises 220 kilometers of sewage pipes ranging from 20 cm to 2 meters in diameter, 40 stormwater relief facilities, and a specialized vacuum drainage (Vakuumentwässerung) system that uses negative pressure to transport sewage in elevation-challenging terrain. Wastewater treatment is delivered jointly with the city of Sindelfingen through the Kläranlage Böblingen-Sindelfingen, which incorporates mechanical screening, biological treatment, flocculation filtration, and activated carbon filtration, and serves roughly 99% of Landkreis Böblingen residents.

SEBB processes approximately 2.8 million cubic meters of wastewater annually and generates roughly €4.3 million in annual fee revenue (Gebührenaufkommen). Revenue is derived from three streams: recurring wastewater fees (Schmutzwassergebühren) billed per cubic meter of fresh water consumed, recurring stormwater fees (Niederschlagswassergebühren) billed per square meter of impervious surface connected to the system, and one-time canal contributions (Kanalbeitrag) charged at €4.59 per m² of allowable floor space for new connections. Pricing is set by municipal council resolution. Advisory and digital services include backflow protection guidance (Rückstausicherung), flood prevention consulting (Wasserschäden verhindern), and since June 2024 an interactive GIS-based heavy rain hazard map portal at sebb-gis.de displaying three rainfall scenarios.

The organization is led by Werkleiterin Sigrid Müller and operates with a staff of approximately 10 people organized across technical, finance/organization, canal construction, canal maintenance, and network documentation/IT functions. Customer service is delivered through a customer center operated on SEBB's behalf by Stadtwerke Böblingen GmbH & Co. KG, plus phone, email, contact form, and a 24/7 emergency line. Marketing and outreach occur via the stadtentwaesserung-bb.de website and Facebook presence, including videos from the Werkleiterin about construction projects under the city of Böblingen's Arbeitgebermarke / Markenbotschafter employer branding program.

Revenue model

1. Wastewater Fees (Schmutzwassergebühren): Fees calculated based on fresh water consumption for sewage treatment. Revenue supports operation, maintenance, and renewal of the canal network and treatment facilities. Total annual wastewater volume processed is approximately 2.8 million cubic meters.
2. Stormwater Fees (Niederschlagswassergebühren): Fees based on the size and type of sealed/impervious property surfaces that drain into the canal system. Introduced in 2010 following court ruling requiring split wastewater fees. Creates incentives for property owners to reduce sealed surfaces.
3. Canal Contribution (Kanalbeitrag): One-time contribution charged per square meter of allowable floor space for new canal connections. Rate: 4.59 € per m².

Direct peers

• Münchner Stadtentwässerung: Wastewater utility of the city of Munich, operating one of Europe's largest municipal sewer networks and treatment facilities. Direct peer to SEBB in Eigenbetrieb structure, gravity sewer operations, stormwater relief, and split-fee (Schmutz-/Niederschlagswasser) revenue model.
• Stadtentwässerung Stuttgart: Municipal wastewater utility of the city of Stuttgart, also a German Eigenbetrieb operating sewer network, stormwater management, and treatment for a single city. Direct peer to SEBB in operating model, regulatory framework (KAG), and service portfolio including flood protection and customer fee systems.
• Zweckverband Kläranlage Böblingen-Sindelfingen: Joint municipal-purpose association operating the shared wastewater treatment plant for Böblingen and Sindelfingen. SEBB is a member; this is the most operationally direct peer, running mechanical, biological, flocculation, and activated-carbon treatment at a scale SEBB itself does not.
• Eigenbetrieb Stadtentwässerung Reutlingen: Municipal wastewater Eigenbetrieb of the city of Reutlingen in Baden-Württemberg. Operates sewer network and stormwater facilities under the same KAG framework as SEBB and serves a comparable single-city service area.
• Stadtentwässerung Frankfurt am Main: Municipal wastewater disposal arm of Frankfurt am Main. Operates sewer network, stormwater facilities, and treatment plants under the German Eigenbetrieb model, with the same regulatory environment (Hessisches KAG analog) and customer-fee revenue streams as SEBB.
• Stadtentwässerung Köln (StEB Köln): Municipal wastewater utility of the city of Cologne. Operates sewer network, stormwater facilities, and treatment under a comparable German Eigenbetrieb model with split wastewater/stormwater fees — a close functional peer to SEBB.

Others

• Entsorgungsbetriebe der Stadt Stuttgart (EBS): Municipal waste management arm of the city of Stuttgart, focused on solid waste rather than wastewater. Relevant as an adjacent municipal Eigenbetrieb operating under the same KAG fee framework and serving the same city/municipality model as SEBB.

Broad incumbents

• Berliner Wasserbetriebe: Integrated water and wastewater utility for Berlin. Although it covers both water supply and wastewater, its wastewater operations (sewer network, stormwater management, treatment) operate under the same German regulatory and Eigenbetrieb-adjacent framework as SEBB — a much larger incumbent in the same municipal utility category.
• Hamburger Stadtentwässerung (Hamburg Wasser): Subsidiary of Hamburg Wasser responsible for sewer network and stormwater operations in Hamburg. Directly comparable to SEBB on network operations, flood protection (Starkregen) advisory, and customer fee structure, but operates at metropolitan scale.

Regional players

• Stadtwerke Sindelfingen GmbH & Co. KG: Municipal utility of the neighboring city of Sindelfingen and partner in the Zweckverband Kläranlage Böblingen-Sindelfingen. Operates the customer service center on behalf of SEBB and jointly owns the treatment plant — a tightly linked regional peer.
