The water industry is facing challenges because of population increases and the resulting development of agricultural operations. Alternative resources that balance the environment, the economy, and society while lessening the strain on limited water supplies will need to be adopted by farmers. One possibility addressing this dilemma is wastewater reuse. The adoption of Reg. (EU) 2020/741 necessitates a paradigm change by moving away from the “fit-for-all” strategy and toward the “fit-for-purpose” approach, which is now regarded as the foundation of the reuse supply chain. However, despite progress, appropriate rules that clearly and concisely outline the procedures to be followed are still needed. Thus, to establish an interdisciplinary and cooperative research agenda, this study tackles the potential and forces behind change by concentrating on tactics for long-term fixes. The need to look at consumer and farmer acceptability as well as the overall environmental advantages of carbon footprint reduction and wastewater fertigation are interesting research avenues. Nutrient-rich streams in agriculture may increase carbon absorption and reduce greenhouse gas emissions from the soil while simultaneously serving as a fertilizer substitute. The literature suggests that additional research is necessary to fully explore the significant economic potential.
