Abstract

Construction industry can be known as one of the prominent natural resource consumers compared to all other industries. Among these natural resources, water can be identified as one of the major concerns worldwide at present. Especially in urban area water distribution for essential activities of human beings is also becoming a challenge in most of the countries. As the consumption of natural resource is considerably high in construction industry, moving towards sustainable construction has been recommended. The linear approach, which the construction industry has been practising for years related to all kinds of resources, has become a threat towards the sustainable construction. Construction sector accounts for about 30% of the world's freshwater consumption. In Sri Lankan construction industry, the focus on management of water is limited. Among the natural resources urban water holds a significant place. While highlighting the importance of urban water management, this paper aims to explore the key challenges in circular water management in Sri Lankan construction industry. 12 semi-structured interviews with industry practitioners and academic experts on circular economy were conducted and the data were analysed using manual content analysis. The findings revel that most of the challenges in implementing circular water management in the construction industry in Sri Lanka are due to lack of awareness, realisation, involvement, and commitment by both citizens and the government. Hence the paper has recommended 6R concept towards implementing circular urban water management within the Sri Lankan construction industry as the authors believe that managing urban water is one of the significant actions to be considered now before it becomes too late in achieving long term sustainability.
斯里兰卡建筑行业城市水资源循环管理面临的挑战
与所有其他行业相比,建筑业可谓是自然资源消耗大户之一。在这些自然资源中,水是目前全球关注的主要问题之一。特别是在城市地区,人类基本活动所需的水分配在大多数国家都成为一项挑战。由于建筑业对自然资源的消耗量相当大,因此建议采用可持续的建筑方式。建筑行业多年来一直采用的与各种资源相关的线性方法已成为可持续建筑的威胁。建筑行业的淡水消耗量约占全球淡水消耗量的 30%。在斯里兰卡的建筑行业中,对水资源管理的关注十分有限。在自然资源中,城市水资源占有重要地位。在强调城市水资源管理重要性的同时,本文旨在探讨斯里兰卡建筑行业在循环水资源管理方面面临的主要挑战。本文对行业从业人员和循环经济方面的学术专家进行了 12 次半结构式访谈,并采用人工内容分析法对数据进行了分析。研究结果表明,斯里兰卡建筑行业在实施循环水管理过程中面临的大部分挑战都是由于公民和政府缺乏意识、认识、参与和承诺造成的。因此,本文推荐了在斯里兰卡建筑行业实施城市水资源循环管理的 6R 概念,因为作者认为,城市水资源管理是现在就应考虑的重要行动之一,以免为时已晚,无法实现长期的可持续发展。
