Spain's Reservoirs at 51.29% Capacity Amid Water Conservation Push
Spain's reservoirs are at just over half capacity with slight declines, prompting government advice on household water savings.
- • Reservoirs in Spain are at 51.29% capacity as of November 7, 2025, holding 28,745 hm3 of water.
- • There was a 165 hm3 decrease in water levels compared to the previous week, a 0.29% drop.
- • Regionally, Catalonia has the highest reservoir capacity at 70.92%, Murcia the lowest at 22.97%.
- • Miteco recommends water-saving measures at home, like using low-consumption dishwashers and phosphate-free detergents.
Key details
As of November 7, 2025, Spain's water reservoirs hold 51.29% of their total capacity, with 28,745 hectometers cubed (hm3) of water stored out of a total capacity of 56,041 hm3. This reflects a decrease of 165 hm3 compared to the previous week, marking a weekly percentage drop of 0.29%, according to the Peninsular Hydrological Bulletin from the Ministry for the Ecological Transition and the Demographic Challenge (Miteco).
Compared to the same period last year, when reservoirs were at 50.03% capacity holding 28,035 hm3, the situation remains concerning for Spain's water supply. Regionally, reservoir levels vary significantly: Catalonia has the highest capacity at 70.92%, while Murcia reports the lowest at just 22.97%.
Miteco has issued recommendations to encourage water savings at home, particularly in the kitchen. These include washing dishes using basins, choosing low-consumption dishwashers that use less than 10 liters per cycle, and using phosphate-free detergents. The Ministry also warns against disposing of used cooking oil via the sink to prevent pollution.
These data highlight the ongoing challenges Spain faces in water management, emphasizing the need for household conservation practices to help maintain reservoir levels vital for daily life and various industries across the country.
