A recent report highlights that 60% of water usage in Madeira remains unbilled, raising concerns about resource management. Despite improvements since 2020, significant volumes remain untracked, particularly in Machico.

A staggering 60% of the water usage in Madeira is not being billed, according to a recent report by Diário de Notícias Madeira. This revelation underscores ongoing challenges in water resource management on the island, a concern for both residents and local authorities.

The report indicates that the percentage of unbilled water has decreased from 69.7% in 2020 to 60.1% in 2025. However, approximately nine million cubic meters of water still remain outside the billing system. This issue is most pronounced in the municipality of Machico, which records the highest level of unaccounted water among the five municipalities managed by the public water company, ARM.

Water management is a critical issue for Madeira, an island reliant on its natural resources to support both its local population and its thriving tourism industry. The inefficiencies in water billing not only represent a financial loss but also pose environmental concerns, as they may indicate potential leaks or unauthorized usage.

Efforts to improve the situation have been ongoing, with ARM implementing various measures to enhance water tracking and billing accuracy. However, the persistent high level of unaccounted water highlights the need for more robust strategies and perhaps new technologies to address the issue effectively.

For tourists visiting Madeira, understanding the island’s commitment to sustainable resource management can enhance their appreciation of the local environment and its challenges. Meanwhile, residents continue to call for increased transparency and efficiency in water management practices.
