Portugal’s Algarve Region Sets the Gold Standard for Drinking Water Quality
Southern Portugal is leading the way in water safety, earning global recognition for its exceptional tap water standards.
The Algarve—famous for its stunning coastline and tourism appeal—has once again proven its commitment to public health. Seven local water management entities have received the prestigious “Exemplary Quality of Water for Human Consumption” seal from Portugal’s Water and Waste Services Regulatory Authority (ERSAR).
A Decade of Excellence
Portugal is celebrating 10 consecutive years of outstanding performance in water safety. The country’s “Safe Water” indicator remains at an impressive 99%, with 2024 recording a 98.86% compliance rate. This achievement reflects a nationwide effort to ensure clean, safe drinking water for millions.
What Does ‘Exemplary’ Mean?
To earn this distinction, providers must meet strict criteria:
- 100% completion of scheduled water quality tests
- ≥99% compliance with health safety standards
- Zero harmful bacteria (including coliform and E. coli)
- Timely reporting of quality control programs
These benchmarks guarantee that consumers receive water of the highest quality.
Algarve’s Champions
Seven organizations in the Algarve stood out:
- Ambiolhão
- Municipal authorities in Albufeira and Lagos
- EMARP (Portimão municipal company)
- Infralobo, Inframoura, and Infraquinta (Loulé municipality)
Nationwide, 72 entities earned the seal, collectively serving over 50% of Portugal’s population.
Why It Matters Globally
Clean drinking water remains a challenge in many parts of the world. Portugal’s success story demonstrates how strong regulation, local accountability, and sustained investment can deliver long-term public health benefits.
The awards will be presented on November 18, 2025, at the National Meeting of Water and Sanitation Management Entities in Santa Maria da Feira.
Key Takeaway
Portugal is setting a benchmark for water safety that other nations can—and should—follow.
