“…Over the last two decades, the volume of water reused for all purposes has increased significantly: from 268 hm 3 in 2000 to 532 hm 3 in 2020 (see Figure 1). However, this increase has fallen short of initial expectations [28]. Current figures significantly deviate from the targets set by the 2012 National Water Reuse Plan, which estimated an annual reuse volume of 1403 hm 3 in 2021.…”

The water sustainability of the Segura River Basin (SRB), located in southeastern Spain, is being challenged as conventional available water sources fall short of meeting the authorised demands of the basin. In recent years, non-conventional water (NCW), such as desalinated and reclaimed water, has become part of the resource pool. However, it has not yet become crucial for irrigation water supply due to its relatively high cost and lower quality compared to conventional water. The new political framework in Spain, developed in the context of ecological transition, marks a notable shift for non-conventional water as a strategic resource for agriculture. This study examines the drivers and barriers influencing its acceptance through an analysis of farmers’ perceptions, conducted through interviews with twelve irrigation communities’ (ICs) representatives of the basin. Discriminant analyses of the data show that the farmers’ experience, along with factors pertaining to production, storage, and transportation costs, determines the acceptance and use of NCW.

“…Before calculating the traditional indicators, and in order to complete a detailed LCCA, it is also crucial to develop an initial cost structure based on the start-up costs that are needed for the constructed wetland (Bassi et al, 2022;Bolinches et al, 2022). For this survey construction and operational costs have been evaluated based on primary data.…”

“…Including costs to the economic analysis enhances the comparison of the benefits or savings against the expenses derived from the initial investment and its subsequent operation and shows if profits outweigh expenses and whether the project may provide a net benefit (Bolinches et al, 2022). Production costs in reference to the expenses involved in the useful life of the VFCW and may be fixed or variable.…”

Research background: The increasing water demand together with an unceasing production of wastewater worldwide has resulted in a situation where the scarcity and pollution of water resources are jeopardizing and depleting such a vital asset. Purpose of the article: In this context, Nature Based Solutions (NBS) such as Vertical Flow Constructed Wetlands (VFCWs) are key because of their capacity of channelling a waste into a resource. However, and notwithstanding their essential role, their financial benefits too often go unnoticed because of missing research that study them from an economic perspective and this article has covered this existing gap. The objective of this research is to analyse the economic consequences of using VFCW against its traditional alternative through a comprehensive economic assessment. Methods: After doing a Life Cycle Assessment (LCA), a combination of two approaches has been carried out. This research has developed a holistic approach where a Life Cycle Cost Assessment (LCCA) based on a Cost Benefit Analysis (CBA) along with an economic evaluation of cleaning environmental costs have been calculated for two different scenarios. For this monetary analysis, the environmental externalities derived from the use of cleaning the pollution caused by a public water supply and sewerage system and the VFCW have been quantified. Findings & value added: Results conclude that VFCW apart of being a cost-effective and profitable alternative for an investor, it has also valuable benefits for the society in general because of its meaningful and positive externalities and the high removal cost of the environmental pollutants of the traditional water supply and sewage system both contributing directly to the achievement of Sustainable Development Goals (SDGs). Furthermore, 4/5 environmental impacts derived from the use of traditional alternative pollute more than twice as much as the VFCW does. Lastly, the cleaning costs difference between both alternatives is 1,984,335?.

Hydrogels possess a strong water absorption capability and can release absorbed water in response to physical or chemical stimuli, making them promising materials for water recycling. To explore the concept of using hydrogels to recover water from wastewater, we synthesized and utilized poly(acrylic acid-co-acrylamide) (PAAM) hydrogels to extract water from solutions containing various organic pollutants and salt concentrations. The swelling ratio of PAAM hydrogels reached up to 510 g/g with a water recovery of around 44% and a water production rate of approximately 3200 L/kg/day. The removal rates of organic pollutants reached up to 89%, depending on the pollutant’s properties such as molecular weight, functional group, solubility, and charge. This confirms the potential of using hydrogels to recover water from various wastewaters, especially for those containing large molecular pollutants.
