Drinking water in Catania
One supply zone, water supplier: ESM (Energie für Sie).
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.

ESM (Energie für Sie)Assigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 07/07/2025. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

Frequently asked questions about drinking water in Catania
- How hard is the water in Catania?
- ESM (Energie für Sie) publishes a total hardness of 0,84 mmol/l for the supply zone Selb - West / Entnahmestelle Bognerschule — that corresponds to 4.7 °dH. 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 Catania?
- ESM (Energie für Sie) publishes a nitrate value of 17,9 mg/l for the supply zone Selb - West / Entnahmestelle Bognerschule. The statutory parametric value is 50 mg/l; the measured value represents 36 % of the parametric value. Basis: Publication by the water supplier, retrieved on 11/07/2026.
- Who supplies the drinking water in Catania?
- ESM (Energie für Sie). The values shown here come from the supply zone Selb - West / Entnahmestelle Bognerschule 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.
