Today, researchers and policymakers are always having brainstorming sessions to find new pathways to stimulate growth, and the rise of environmental issues such as food security, water waste, and energy-using problems, global warming, and climate change. There are many ideas to promote economic development while responding to climate change, loss of natural capital and resources, and addressing social or development objectives to have a vision to protect nature, especially water waste problems. Water is the core element of human beings in the last decades; it is known that freshwater resources have become scarce. There might be a crisis because of the many challenges, including a scarcity of fresh water. Considering the importance of better wastewater management in this study, we explore wastewater reuse percentages in selected OECD countries between 2015 and 2022. A multistage analytical framework was adopted to examine the determinants and dynamics of treated wastewater reuse. The study examines a detailed look at the most popular challenge to find new solutions. The purpose of this research is to build creative and innovative ways to guide future researchers. Finally, the aim is to try to create a vision for the Green Earth.
