Deseasonalize the lack of water
Traditionally, it is in the summer when we want to live in old properties that, due to lack of water, are hardly habitable. The owners disinvest and end up putting them up for sale … “Farm for sale with olive trees, almond trees and carob trees with cistern” Empty water cistern.
When the area is close to the beach, the tourist demand justifies the investment and the houses are repaired and made livable with the indispensable hiring of water tankers.
In places where water is not abundant, normally the quality of the cistern water is not constant because the catchments are at their limit and the aquifers are salinized. In places like the one on the island of Formentera, you need to hire cheap water tankers for sanitary water and buy bottled water separately for consumption. The Balearic Government tries to find alternative solutions to the use of plastic packaging to reduce its strong environmental impact, but it is not easy because the tourist population spreads in the summer months and the consumption of mouth water is high in the llards and in the hospitality industry.
Thinking about the small or medium volumes for consumption that a house needs, there is a new technology to consider in terms of autonomy and sustainability:
Atmospheric drinking water generators
The water produced with atmospheric drinking water generators has a quality controlled by the user himself and generates virtually no waste. The equipment is easy to amortize if you compare it with the price of bottled water which is 10 times more expensive.
A water generating equipment only needs two things to work: air and electricity as a power source. If it is combined with a photovoltaic source, we can say that the generation cost of the liter once the equipment has been amortized is practically at zero cost and is sustainable.
