Tagus Water Authority Upgrades SAIH for Enhanced Storm Management and Water Security

The Tagus Water Authority (CHT) is upgrading its Automatic Hydrological Information System (SAIH) to bolster water resource management and prevent natural hazards in the Tagus basin. The project, demonstrating its effectiveness in managing major storms in the first few months of 2025, solidifies the Tagus SAIH as a crucial infrastructure for water security in central Spain.

Spanning over 55,000 km2 and home to nearly eight million people, the Tagus basin's complexity demands advanced project management. The SAIH network comprises 222 stations, 30 water quality stations, 12 river gauging stations, and over 100 piezometers. The upgrade aims to enhance hydrological forecasting, anticipate pollution episodes, and promote sustainable resource use.

The project involves the Spanish Ministry for the Ecological Transition and the Demographic Challenge, the Confederación Hidrográfica del Tajo, and regional scientific and technological organizations. Idrica and Adasa Sistemas are collaborating, with Idrica leading the hydrological aspects. The upgrade involves corrective, preventive, and ongoing maintenance of equipment and IT infrastructure throughout the basin. It positions the Tagus basin as a benchmark in digital water management solutions.

The upgrade of the Tagus SAIH ensures water and hydraulic security for all users in the basin, facilitating real-time decision-making. By improving hydrological forecasting and anticipating pollution episodes, the project advances sustainable resource use in the complex Tagus basin, setting a digital water management standard for central Spain.
