Social acceptance of water quality through decentralized greywater treatment using green wall system

BACKGROUND AND OBJECTIVES: Addressing water scarcity through innovative and sustainable solutions is crucial in regions like Jordan, where resources are limited, and community involvement plays a pivotal role in ensuring success. This study examines the social acceptance and readiness of university dormitory residents, specifically female students at Al-Zahra’a Dormitory, the University of Jordan, for implementing a decentralized greywater treatment system using green walls. The objectives of the current study was to explore the social dynamics surrounding the implementation of decentralized greywater treatment systems, with a focus on fostering public acceptance and ensuring sustainable adoption in urban contexts.METHODS: The study evaluated the technical performance of the greywater treatment system by analyzing the treated effluent quality against Jordanian standards to assess its suitability for reuse in toilet flushing and irrigation. Additionally, a structured questionnaire with 24 questions was distributed to dormitory residents and staff to explore social acceptance. Responses were categorized into four thematic groups: 1) Awareness and Understanding, assessing participants’ familiarity with greywater treatment; 2) Perceptions and Attitudes, evaluating opinions and concerns regarding the system; 3) Environmental Impact, examining perceived benefits and potential drawbacks; and 4) Participation and Support, measuring willingness to engage in operation and maintenance activities. This mixed-methods approach provided comprehensive insights into both the technical feasibility and social dynamics of system implementation.FINDINGS: The findings indicate that 90 percent of respondents are aware of water scarcity, with the majority strongly supporting innovative solutions like the green wall system. The study emphasizes the critical role of community participation in the success of sustainable systems. Notably, 82 percent of respondents expressed interest in training programs on the operation and maintenance of the greywater system, demonstrating a proactive attitude toward its long-term sustainability. Additionally, 87 percent supported expanding the system beyond the dormitory to other residential areas, signaling broad acceptance and potential for larger-scale application. However, concerns regarding potential issues such as odor and health impacts were noted, with nearly 50 percent of participants expressing discomfort.CONCLUSION: Overall, strong community interest and readiness for green wall-based greywater systems highlight their potential to address water challenges. Continuous monitoring, system optimization, and stakeholder collaboration are essential for long-term success. Clear protocols, training, and improved management can mitigate health and environmental concerns, fostering user trust. Expanding these systems to other areas with community involvement and outreach programs can amplify impact. Further research on social acceptance will refine strategies and support broader implementation of decentralized greywater treatment initiatives.
