Dresden's main treatment plant at Kaditz serves about 700,000 connected inhabitants and is sized for 874,000 population equivalents. Sludge digested on site yields biogas that is burned in combined heat and power units; a 275-metre channel carrying the cleaned water down to the Elbe drives a turbine whose generator feeds electricity back into the plant, and photovoltaic modules sit on the roof of the stormwater overflow basin. The utility also draws heat from the ground and from the wastewater itself.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →📊 Impact
The sludge-gas CHP units produce about 18,000 MWh of electricity a year — the annual consumption of about 6,000 households — covering almost 85% of the total energy demand of wastewater and sludge treatment at Kaditz, according to the operator's 2023 plant brochure. An earlier account by the same utility put three CHP units at about 70% of its energy demand. The rooftop photovoltaics and the outflow turbine add to this; neither carries a published rating or annual output.
🎓 Lesson
Two shares circulate for the same plant and they are not the same measurement: about 70% of the utility's energy demand in the earlier account, almost 85% of the energy demand of wastewater and sludge treatment at Kaditz in the 2023 brochure. Only the second is about this plant's own processes, and the difference is a denominator rather than a gain. The other two generators are named in every description and quantified in none — the solar array and the outflow turbine have no published capacity or yield, so "energy-autonomous" rests on the digester, and the digester rests on sludge the city would have to treat anyway.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
