During the last decades, the shortage of a basic resource such as water is being accentuated in many territorial areas such as the Valencian Community, and this represents serious effects on our environment and our economy. In addition, according to current forecasts, global demand for water will exceed 40% of the available resources by 2030. Therefore, apart from adopting water efficiency measures, it is advisable to tackle the reuse of wastewater treated as a means safe and viable to increase the water supply by reducing the pressure on already overfished water resources.
It is required to reconsider our traditional focus on water consumption in order to adopt new strategies that make this vital resource reusable to the maximum possible. This change of paradigm means moving towards a circular economy approach in which wastewater is no longer seen as waste, but as a valuable resource in a context of water shortages. A combination of regulations, incentives and the intervention of all the actors involved will be key to transforming the water resources management criteria.
In turn, the reuse of water in agriculture also contributes to the recycling of nutrients by promoting a lower use of chemical fertilizers. These effects are especially relevant in the case of the Valencian Community. For all this, the promotion of the sector of the reuse of wastewater treated, should have a special role in the framework of the circular economy.
