Hardness, nitrates, pH, sanitary compliance: the real tap water quality in Schiltigheim (moderately hard water), with official Hub'Eau data updated monthly.
✓ Compliant with sanitary standardsSchiltigheim water reaches 24.8°f — a moderate level reflecting local geology. Limescale is visible on shower glass and taps but has no impact on sanitary water quality. Standard dishwasher tablets, regular regenerating salt and periodic coffee maker descaling are the only routine precautions needed. Official sanitary tests declare it compliant with current standards across all monitored parameters.

Sanitary compliance summarises adherence to French regulatory limits across all analysed parameters (bacteriology, chemistry, radioactivity). Compliant water can be consumed directly from the tap without additional treatment.
The TH (titre hydrotimétrique) measures calcium and magnesium concentration, expressed in French degrees (°f). The higher it is, the harder the water and the faster limescale deposits on surfaces and in appliances.
Nitrates come mainly from agriculture and waste water. The French regulatory limit is 50 mg/L; below 25 mg/L, the level is considered low.
pH measures water acidity. Regulations require a value between 6.5 and 9: outside this range, water may encourage pipe corrosion or affect taste.
Free chlorine is added to disinfect water and prevent bacterial growth in the distribution network. High levels can produce a perceptible taste or odour, without health risk at authorised levels.
Turbidity measures water clarity, in NTU (nephelometric turbidity units). A low value indicates clear water with few suspended particles.
Conductivity reflects overall water mineralisation, in µS/cm. It has no strict sanitary threshold but indicates the dissolved mineral salt content.
Maintenance budget: ~£69/year
For 2 persons, water at 24.8°f deposits around 1.2 kg of limescale per year in your appliances. Estimated cost in descalers, salt and filters.
Calcium: ~40 mg per litre
Your water provides 40 mg of calcium/L, which is 4% of the recommended daily intake.
Filter jug: cartridge every 5 months
At 24.8°f, replace the cartridge every 5 months. An under-sink filter lasts 6 to 12 months.

Schiltigheim ranks 76th out of 91 cities in the department in our database.
Tap water in Schiltigheim has a quality index of 5.1/10 (average quality) in our database, calculated on nitrates, PFAS, pH, free chlorine and turbidity. This is a comparative reading of Hub'Eau data, not an official rating.
Tap water hardness in Schiltigheim is 24.8°f (French degrees), making it moderately hard water. The average is 23.5°f in the Bas-Rhin department and 22.1°f across our entire database.
Moderately. At 24.8°f, water in Schiltigheim is moderately hard: limescale traces appear over time on surfaces that aren't wiped down, but not a daily problem with regular maintenance.
Not necessarily. At 24.8°f, regular antiscale maintenance is often sufficient; a softener is worth considering mainly if deposits become bothersome daily.
Yes. In the last available official sanitary analysis (10 June 2026), water distributed in Schiltigheim was declared compliant, meaning it can be drunk directly from the tap. Official conclusion: "Eau destinée à la consommation humaine conforme aux limites et aux références de qualité réglementaires pour les paramètres analysés." This is a point-in-time sample, not real-time monitoring.
The pH measured in Schiltigheim is 7.4. Regulations require a value between 6.5 and 9: the water is within this range.
Compare tap water quality in other cities of the Bas-Rhin department, ranked by quality index.
Methodology: the quality index compares each city against the 4806 other cities in our database on 5 parameters (nitrates, PFAS, pH, free chlorine, turbidity) and averages its relative position on each. This is not an official rating, only a simplified comparative reading of Hub’Eau data.
