Community Awareness of the Application of Floating Treatment Wetlands Improving of Polluted Canal Environment

Canal pollution poses a persistent environmental challenge in Ho Chi Minh City (HCMC), Vietnam, requiring innovative and sustainable restoration approaches. This study examined residents’ perceptions of the structure, functions, and benefits of Floating Treatment Wetlands (FTWs)—a nature‐based solution implemented in the Hang Bang Canal to enhance water quality and urban landscapes. Data were collected from a survey of 202 residents and visitors between March and April 2024 using questionnaires that assessed demographics, perceptions of canal pollution, and evaluations of FTWs. Results indicated that most participants were aware of the FTW system through direct observation, with 36.6% visiting the site daily. The majority (86.6%) appreciated its landscape function, and 61.9% recognized its role in water filtration. Plants were the most favored component (78.7%), followed by environmentally friendly materials such as bamboo (58.7%). Furthermore, 80.2% identified landscaping and 64.3% identified improved water quality as the main benefits of FTWs, while 17.8% expressed concern about mosquito breeding. Awareness of canal pollution was higher among younger and more educated respondents. Overall, 82.2% were willing to recommend FTWs, and 62.4% showed interest in participating in their management—mainly through garbage collection (87.3%). Logistic regression analysis confirmed associations between awareness and demographic factors, including age, education, and occupation. The findings highlight FTWs’ potential for urban water restoration and underscore the importance of integrating community education and participation to enhance public support and ensure long‐term sustainability.
