摘要

达卡是孟加拉国唯一的特大城市,由于无规划的城市化和缺乏可持续的水资源管理方法,达卡正面临着水资源紧张的问题。城市水资源综合管理的两个重要组成部分,即雨水收集(RWH)和废水回用,在达卡几乎没有实施。为满足中等收入群体的居住需求,达卡正在建设一个新城镇,这为整合这两个系统提供了机会。然而,这种整合要么缺失,要么缺乏可持续性考虑。本研究采用结构化问卷调查的方式,探讨了 256 名受访者(受益人和职能部门)的看法,以确定在不断发展的乡镇中整合农村用水和污水处理系统的机遇和挑战。通过问题探讨了受访者的意识、知识水平、意愿和主要需求。不同年龄段的受访者对回用水和废水再利用的总体认识水平分别在 30% - 62% 和 34% - 42% 之间。约有 70% 的受访者缺乏有关实施监管方面的知识。除经济方面的见解外,约 64% 的受访者愿意将其纳入城市水需求管理。要抵消这两部分的不被采纳,关键在于全面提高意识、强制执行和简化整合过程。

Social perception on rainwater harvesting and wastewater reuse: Opportunities and challenges of a fast-growing township in Dhaka

Dhaka, the only megacity of Bangladesh is facing water stress due to unplanned urbanization and lack of sustainable water management practices. The two important components of Integrated Urban Water Management, i.e., rainwater harvesting (RWH) and wastewater reuse are hardly practiced in Dhaka. A new township is growing in Dhaka to meet the dwelling needs of middle-income groups with the opportunities to integrate both the systems. However, the integration is either missing or lacks considerations of sustainability. This study explores the perceptions of 256 respondents (beneficiary and functionary) to ascertain the opportunities and challenges of integration of RWH and wastewater of the growing township using structured questionnaires. The awareness, level of knowledge, willingness and key necessities have been explored through the questions. The general awareness level on RWH and wastewater reuse ranges between 30% - 62% and 34%- 42% respectively for different age groups. Around 70% of the respondents lack knowledge on regulatory aspects of its implementation. Apart from economic insights, the perception reveals around 64% willingness towards its integration for urban water demand management. Complete awareness generation, enforcement of compliance and streamlining the process of integration are the key imperatives to offset the non-adoption of both components.
