Reuse of Water for Sustainable Irrigation of the “Irailaren 23” square in Erandio, Spain

The European Water Charter, proclaimed by the Council of Europe in Strasbourg on May 6, 1968, was a statement of principles for proper water management in which it was stated that “freshwater resources are not inexhaustible” [1]. To speak of Responsible Consumption is to address the problem of hyper-consumerism in developed societies and powerful groups in any society, which continue to grow as if capacities were infinite. To this end, at the Johannesburg summit in 2002 [2], the following was pointed out: “15% of the population living in high-income countries are responsible for 56% of the world’s total consumption, while the poorest 40% in low-income countries are responsible for only 11% of consumption”. On the other hand, the Royal Society’s report of 2000 [3] noted that current consumption trends are unsustainable, that there is a real need to reduce consumption and that “to preserve human well-being in the long term, people need to move towards new ways of meeting human needs, adopting patterns of consumption and production that maintain the Earth’s life-support systems”. It is therefore necessary to apply the three R’s rule: Reduce, Reuse and Recycle.
