Integrating public perception and policymakers' views on treated wastewater lagoon and reuse management in Qatar

ABSTRACT

Artificial lagoons are unique structures that serve as key reservoirs for surplus treated wastewater (TWW), presenting unique challenges and opportunities for sustainable urban water management in hyper-arid environments such as Qatar. Despite their important role, policymakers have been cautious with TWW reuse due to perceived public resistance, as public knowledge, awareness, and involvement in lagoon management remain limited, which may impact effective future management of such systems. Public perceptions and knowledge of artificial lagoons are addressed in this study using an online survey. Semi-structured interviews are used to explore policymakers' understanding and willingness to involve the public. Results reveal a public desire to have more knowledge about lagoon locations, water sources, benefits, and safety risks. Interestingly, while the policymakers' plans for the lagoons in Qatar are in transition, this study shows the public willingness for more TWW reuse, presenting an opportunity to transform TWW from a disposal challenge to a resource within a circular water economy. These findings highlight the critical role of informed public participation and policy alignment for sustainable urban water management practices in hyper-arid regions.
