Resolution No. 60/2026 establishing the conditions for access, supply and use of desalinated water produced and/or distributed by the irrigation entity, Água de Rega (AdR, SA) in the Municipality of São Domingos, with a view to promoting the efficient and sustainable use of water resources.

This Resolution establishes a regulatory framework for the access, supply, and use of desalinated water in the Municipality of São Domingos, with the primary objective of promoting the efficient and sustainable management of water resources. It responds to increasing water scarcity driven by climate change and to the fact that agriculture consumes the largest share of national water resources. It aims to ensure an equitable and well‑regulated distribution system operated by the public irrigation entity Água de Rega (AdR, S.A.), while supporting the transition toward a modern agricultural economy based on efficient irrigation technologies such as drip irrigation. Its overarching goal is to minimize water shortages, reinforce resilience in agricultural production, and guarantee that the growing demand for irrigation water is met in a sustainable manner. In addition, the resolution seeks to safeguard long‑term agricultural productivity and food security by establishing eligibility criteria for users, defining the technical and contractual obligations for water use, and setting clear rules on consumption limits and monitoring. It emphasizes sustainable farming practices, efficient irrigation scheduling, and responsible fertilization, while prioritizing desalinated water for areas with poor‑quality or insufficient groundwater. The resolution also outlines economic mechanisms—including pricing based on production costs and potential subsidies—to encourage efficient use of desalinated water.
