“…In the EU, the reuse of reclaimed water is considered a possible alternative water supply, with the advantages of negligible effects on food production and income of farmers [70]. In a previous study in Santiago de Chile (Chile), it was estimated that graywater reuse would ultimately decrease the consumption of fresh water by hundreds of liters per month if additional permission for graywater reuse is obtained [71]. The importance of graywater reuse has also been reported in other studies [72,73].…”

The exacerbation of the global water crisis due to an increase in global population, industrialization, urbanization, and agricultural activities, along with global climate change and limited water resources, makes water reuse inevitable in all continents. By 2030, global water consumption may grow to ~160% of the currently available volume. This study reviews recently published articles (2019–2021) to explore global case studies of water reuse and discusses future perspectives by country based on a literature survey on water reuse. There are 17 obstacles reported worldwide regarding water reuse (e.g., the properties and low amounts of treated water, regulations, financial challenges, etc.) and 10 advantages of utilizing reused water in various fields (e.g., overcoming the global water crisis, improving the economy, benefiting the industrial sector, etc.). The concept of reusing water has been accepted by countries in almost every continent (e.g., Australia, Europe, Asia, Africa, South America, and North America); the technical findings from different countries are summarized in this study. The water reuse scenario is not restricted to countries with limited water supply and can be applied to those with sufficient water resources (e.g., Canada and Brazil have also implemented water reuse policies). Water reuse can be utilized by human beings via indirect and direct potable recycling, as well as in agriculture, textile, construction, hotel, groundwater recharge, and aquaculture industries. However, a standard guideline for the application of reclaimed water at a global scale is unavailable. Several perspectives have been suggested for the future utilization of reclaimed water worldwide as an effort to secure and ensure the sustainability of existing natural water resources. Lastly, water reuse may be considered a potential alternative for reducing the burden on water resources in the future.

“…A recent study [136] analyzed the potential capture of greywater reuse using existing research on consumer preferences, taking Santiago, Chile as a case study. Their study concluded that there is a need to use advanced mathematical models that bring together economic theory and behavioral underpinnings from psychology.…”

Water scarcity is a problem of global relevance that is affecting more and more people in the world. Latin America and the Caribbean (LAC) have around 35% of the world’s renewable water resources. However, the management of water resources and inequality in access to water has made water scarcity a problem of growing interest in the region. The reuse of water could be an efficient measure to reduce the demand for water resources in the area. In particular, the reuse of greywater is a simple and decentralized method of water reuse, which would mitigate the impact of the lack of water in isolated or difficult-to-access areas. Using the Aquastat database, water consumption in the world and water availability in LAC were studied. In addition, the regulatory framework for water in LAC countries was studied, with an emphasis on water reuse and greywater legislation. Agriculture is one of the most demanding of water in the world, particularly, in LAC, which demands around 70% of renewable water resources. Furthermore, in LAC, the availability of drinking water in rural areas is lacking, with seven countries having less than 80% access to healthy drinking water. The water regulation in LAC is quite heterogeneous. The most general regulation around water is found in the political constitutions of each country. Some constitutions explicitly indicate access to water as a human right, while other constitutions do not include information in this regard. Although some countries have specific regulations on the reuse of wastewater, there is a general lack of regulations related to the reuse of greywater. In most cases, the term “greywater” is not even defined in the general water and wastewater laws. As of the date of this article, only Chile, Peru, and Brazil have bills to regulate the reuse of greywater, of which only the Chilean is approved. The reuse of greywater could help reduce water demand for non-drinking uses. However, the implementation of greywater treatment systems represents a cost that is difficult to cover, especially in the poorest countries of the region. Countries must improve their public policies to improve the management, use and reuse of water to mitigate water scarcity that severely affects human consumption in the region. The relevance of this study lies in providing a general framework of the water situation in LAC for studies and public policies focused on promoting water reuse as a measure to mitigate water scarcity.
