The Balearic Islands record the highest average water consumption for dispersed housing in Spain, according to several technical studies, including data from the National Statistics Institute. The research examines domestic water use in rural areas, outlying residential zones and isolated properties, taking into account factors such as climate, housing type and user behaviour.
Annual per capita consumption in these homes is estimated at between 60 and 70 cubic metres in the Balearics. The reports say this pattern reflects a combination of structural and environmental influences.
Housing across the islands is largely characterised by detached properties and chalets, many of them associated with residential tourism. These homes typically use more water than compact urban housing, particularly for garden irrigation, swimming pools and other outdoor needs. The Mediterranean climate, with its long, hot and dry summers, further increases demand, especially over extended periods. This effect is more pronounced where gardens do not feature native or drought-resistant plants suited to local conditions.
Similar trends elsewhere
After the Balearics, regions such as Cantabria, Murcia and the Canary Islands also report relatively high levels of water use, with average consumption exceeding 60 cubic metres per person each year. In Murcia and the Canary Islands, high temperatures and low rainfall make outdoor water use more necessary. In contrast, Cantabria’s higher consumption comes despite its wetter climate, reflecting traditionally elevated household use and a significant share of dispersed housing.
Moderate consumption inland
In inland regions including Castilla y León, Castilla-La Mancha, Galicia and Extremadura, average consumption in dispersed housing is lower, ranging between 50 and 60 cubic metres per person annually. Cooler or more humid conditions, along with lower tourism pressure and fewer outdoor amenities, help to limit overall water demand in these areas.
