How hard is the water in Postcode 01099?

SachsenEnergie Dresden publishes the hardness range weich for the supply zone Coschütz. The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: 25.02.2026, retrieved on 11/07/2026.

How much nitrate is in the drinking water in Postcode 01099?

SachsenEnergie Dresden publishes a nitrate value of 11 mg/l for the supply zone Coschütz. The statutory parametric value is 50 mg/l; the measured value represents 22 % of the parametric value. Basis: 25.02.2026, retrieved on 11/07/2026.

Who supplies the drinking water in Postcode 01099?

SachsenEnergie Dresden. The values shown here come from the supply zone Coschütz and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.

Drinking water in 01099

For this postcode SachsenEnergie Dresden publishes several supply zones. Which of them serves an individual address is not published — below are the values of the zone with the most documented parameters, the remaining 5 underneath.

How to read the share of the parametric value

12 % Share of the parametric value. The proportion of the permitted maximum that the measured value uses — here 12 %, so just over an eighth.

< 10 % * Below the limit of quantification. The substance was not detectable. The mark shows where the detection limit lies relative to the parametric value — the actual share of the parametric value is below that.

Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.

SachsenEnergie Dresden

Assigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.

No date is given for these values. The water supplier publishes the analysis without a sampling date and without a report date. When the water was examined is not apparent from the source — we do not add a date and we do not estimate one. What is stated is therefore only when we retrieved the document.

Trifluoroacetic acid (TFA)	2,5 µg/L	60 µg/l UBA guide value	4 %	Maximum · Source [2]

For trifluoroacetic acid (TFA), the German Drinking Water Ordinance does not specify a parametric value. The comparison is therefore made with the guide value of 60 µg/l issued by the Umweltbundesamt, which has replaced the earlier health-related guidance value of 3 µg/l. A guide value is not a legal maximum but a health-related classification.

Frequent questions about postcode 01099

How hard is the water in Postcode 01099?: SachsenEnergie Dresden publishes the hardness range weich for the supply zone Coschütz. The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: 25.02.2026, retrieved on 11/07/2026.
How much nitrate is in the drinking water in Postcode 01099?: SachsenEnergie Dresden publishes a nitrate value of 11 mg/l for the supply zone Coschütz. The statutory parametric value is 50 mg/l; the measured value represents 22 % of the parametric value. Basis: 25.02.2026, retrieved on 11/07/2026.
Who supplies the drinking water in Postcode 01099?: SachsenEnergie Dresden. The values shown here come from the supply zone Coschütz and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.
