City Drainage Dresden

What City Drainage Dresden does

Stadtentwässerung Dresden GmbH (SEDD) is the municipally-owned wastewater utility of the City of Dresden, Germany, wholly owned through the Eigenbetrieb Stadtentwässerung der Landeshauptstadt Dresden structure. The company operates the central Kläranlage Kaditz wastewater treatment plant — one of Germany's largest, with mechanical, biological, and chemical stages — alongside a ~2,100 km sewer network, special structures (Stauraumkanäle/storage canals, Dücker/underground river crossings, Regenüberlaufbecken, Hochwasserpumpwerke), and digesters for biogas-based electricity generation that cover ~85% of the plant's own electricity demand (~18 million kWh/year). About 570,000 Dresden residents and a base of semiconductor manufacturers (Infineon, Globalfoundries, Bosch, X-FAB, and the planned TSMC/ESMC JV) discharge into the system, with industrial wastewater already representing ~93% of total industrial load (~10 million m³/year, forecast to roughly double).

Revenue is generated from three primary streams: a per-cubic-meter Schmutzwassergebühr (EUR 2.45 from 1 January 2026) and a per-square-meter Niederschlagswassergebühr (EUR 1.64/m²/yr) on sealed surfaces — both statutorily set — alongside usage-based industrial wastewater fees from semiconductor and electronics customers, plus inter-municipal service fees for neighboring authorities (Dohna, Müglitztal, Zweckverband Wilde Sau). Distribution is direct: physical connection to the public sewer, customer service phone (0351 822-3344) and counters, plus online forms — there is no private-sector sales motion given the statutory monopoly.

Strategically, SEDD is committing EUR 630 million of capital investment through 2038 — including the newly completed ~EUR 76 million, 10 km Industriesammler Nord (ISN) dedicated industrial collector, a planned fourth treatment stage for micro-pollutants, new rainwater retention basins, and sludge treatment upgrades — explicitly to absorb the semiconductor industry ramp in northern Dresden. The company also operates outside its core franchise via a BMZ-funded operator partnership with the City of Lviv (co-led with Berliner Wasserbetriebe), environmental analytics for enterprise/municipal clients, and community-facing programs (Schülerlabor Aquamundi, Wasserwelten tours, Tag der offenen Tür attracting ~8,000 visitors). Technology differentiators are operational rather than digital: trenchless Inliner pipe rehabilitation extending sewer life ~100 years, a custom Super-Stauwagen high-pressure flushing vehicle, a UV+activated-carbon odor elimination system at the sludge loading area, and dedicated egg-shaped Faultürme digesters commissioned in 2012 to eliminate natural-gas sludge drying and odor.

Revenue model

1. Schmutzwassergebühr (Wastewater discharge fee): Charge per cubic meter of wastewater discharged to the public sewer network. Applies to all residential, commercial, and industrial users connected to the municipal system. Revenue is set by municipal fee statute and reviewed periodically (last adjusted effective 1 January 2026).
2. Niederschlagswassergebühr (Rainwater runoff fee): Charge per square meter of sealed/impermeable surface (roof, paved areas) connected to the sewer network, charged annually. Derived from property size and surface type.
3. Industrial wastewater treatment fees: Fees from industrial clients (e.g., semiconductor manufacturers Globalfoundries, Infineon, Bosch, X-FAB) for treatment of large-volume industrial wastewater. Industrial wastewater accounts for ~93% of Dresden's total industrial wastewater volume.
4. Service fees (technical services for municipalities): Operating and technical services provided to neighboring municipalities (e.g., Dohna, Müglitztal, Zweckverband Wilde Sau/Wilsdruff) under inter-municipal cooperation agreements.
