Tenerife Faces €1.6 Billion Funding Gap to Secure Water Future and Flood Defenses

Tenerife faces a major financial and operational challenge to secure its water future. A new report by the Association of Construction and Infrastructure Concession Companies (Seopan) and the engineering firm TYPSA estimates that the island needs 1.685 billion euros by 2035 to modernize its water systems and protect against extreme weather.

The report, Strategy and Investments for Water Efficiency and Resilience in Spain, highlights a serious safety concern: over 11,200 residents in Tenerife live in areas at risk of flooding from heavy rain or overflowing rivers. To address this, the study suggests spending 38 million euros on flood defenses, including both structural improvements and nature-based solutions like restoring coastal areas.

Beyond flood protection, Tenerife’s water supply is under pressure from a projected 4% drop in rainfall and high demand from the tourism industry. The bulk of the required investment—1.423 billion euros—is earmarked for upgrading urban water systems. Another 161 million is set aside for climate adaptation, specifically to improve desalination plants for seawater and brackish water.

The proposed plan also allocates 32 million euros for irrigation, 27 million for environmental compliance (including sanitation projects in the port of Santa Cruz), and 4 million for monitoring technology. However, Seopan warns of a significant "execution gap," noting that about 30% of planned water projects fail to move from the drawing board to construction.

The report points to slow public tender processes, which often drag on longer than a single political term, as a major obstacle to managing droughts effectively. Julián Núñez, president of Seopan, emphasized that water scarcity is no longer a temporary problem but a permanent reality. He argues that Spain needs a stable, long-term financial strategy to address a national investment shortfall estimated at over 103.8 billion euros for the next decade.
