About the water supply in Estepona
Estepona's tap water is certified as not safe to drink, with overall quality rated 9/10. The main concern is free chlorine, which affects 5 of the 7 networks, potentially impacting taste and safety for drinking. Other issues include hardness and aluminium, but these only affect some networks, so many residents may still enjoy good quality water in their homes.
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.
0 mg/L. Chlorine is legally required (minimum 0.2 mg/L) to keep water safe as it travels through pipes. Below the recommended minimum — disinfection could be insufficient for long pipe runs.

💎 Water hardness
Category: Hardness · Legal limit: no legal limit
2/10Needs 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
5.5/10Fair
45 µg/L — 45% 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.
