Drinking water in 45549
For this postcode the responsible water supplier 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 11 underneath.
How to read the share of the parametric value
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.

Frequent questions about postcode 45549
- How hard is the water in Postcode 45549?
- Gelsenwasser publishes a total hardness of 7.7 °dH for the supply zone Verbundwasserwerk Essen; Entnahmestelle: Trinkwasser Essen nach UV Ltg. Überruhr, WAA 2 (00-0350) (hardness range weich). 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: Publication by the water supplier, retrieved on 11/07/2026.
- How much nitrate is in the drinking water in Postcode 45549?
- Gelsenwasser publishes a nitrate value of 9,2 mg/l for the supply zone Verbundwasserwerk Essen; Entnahmestelle: Trinkwasser Essen nach UV Ltg. Überruhr, WAA 2 (00-0350). The statutory parametric value is 50 mg/l; the measured value represents 18 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Postcode 45549?
- Gelsenwasser. The values shown here come from the supply zone Verbundwasserwerk Essen; Entnahmestelle: Trinkwasser Essen nach UV Ltg. Überruhr, WAA 2 (00-0350) 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.
