About the water supply in Estepona

Estepona's tap water is certified as not safe to drink in one of its seven networks. While the overall quality is high, with a score of 9.1/10, hardness is a significant concern affecting 5 of the 7 networks, which may impact appliances and taste. Other issues like trihalomethanes and aluminium also affect some networks, but overall, the water is generally safe for daily use.

How to read these scores: 10 = perfect, 0 = at or over the legal limit. A score of 0 does not necessarily mean the water is unsafe — it means that specific parameter is at its maximum legal level. The official SINAC certification (APTA / NO APTA) is the authoritative safety indicator. Only readings from the last year are included — older data is excluded to keep scores current.

💎 Water hardness
Category: Hardness · Legal limit: no legal limit
2/10 Needs attention
411 mg/L CaCO3 — classified as extremely hard. Very hard water — significant limescale buildup on appliances. Water softener or filter recommended for kettles and washing machines. Safe to drink but has a mineral taste. There is no legal limit for hardness as it poses no health risk.

🛡️ Trihalomethanes (THMs)
Category: Safety · Legal limit: 100 µg/L
4.7/10 Needs attention
53 µg/L — 53% of the 100 µg/L legal limit. Trihalomethanes form when chlorine (used to disinfect water) reacts with natural organic matter. They are safe at these levels but are a reason some people prefer to filter tap water. Moderate level — within legal limits but noticeable to sensitive people.
