Tenerife Water Reserves Rise Despite Regional Disparities
Tenerife’s water storage has increased to 43% of total capacity, though the island faces a significant geographical disparity as southern reservoirs undergo essential maintenance.
As September begins, Tenerife’s water management presents a mixed picture: while overall water storage has improved compared to last year, there is a significant gap between the north and south of the island. According to the Tenerife Island Council (Cabildo de Tenerife), the island’s reservoirs currently hold over 2.1 million cubic meters of water, reaching 43% of their total capacity.
This is a positive shift, with 420,089 cubic meters more water stored than at this time last year—a 4.2% increase. However, this average hides a clear geographical divide: northern reservoirs are at 49.3% capacity, while those in the south are at just 29.6%.
Valentín González, Councilor for the Primary Sector, explained that the southern shortage is due to several factors. High summer demand has put pressure on reclaimed water supplies, and the Valle San Lorenzo reservoir has been temporarily taken offline for essential repairs. Crews are currently re-waterproofing the reservoir’s lining to ensure it remains efficient and leak-free.
The Council expects the Valle San Lorenzo facility to be fully operational again by the end of September. This should help boost storage levels in the south and balance out the island’s water distribution.
This situation highlights how much the island relies on both stable infrastructure and careful management, especially as reclaimed water becomes vital for local agriculture. Despite the current challenges in the south, the Council confirms that the island’s overall ability to manage water supplies has improved compared to 2025.
