Abstract

In the context of growing urbanization, sanitation in many cities is in acute crisis with severe social and environmental consequences. The Sustainable Development Goal (SDG) of sanitation for all by 2030 is increasingly elusive. Municipalities have been experimenting with a range of lower-cost sanitation solutions. Simplified Sewerage Systems (SSS) have emerged in different cities as one response, but with mixed results. This paper evaluates an SSS project in an informal settlement in Dar es Salaam, Tanzania. Drawing on a combination of a survey and focus group discussions, the paper examines the social and economic impacts of the SSS and identifies a set of key concerns for future urban sanitation interventions: affordability, maintenance and governance. We conclude by considering the implications for future research and practice on urban sanitation, including the limits of technology-based approaches and the necessity to focus on the diverse needs of residents in place.

达累斯萨拉姆的卫生挑战:简化污水系统的潜力

在日益城市化的背景下，许多城市的卫生设施面临严重危机，造成严重的社会和环境后果。到2030年人人享有卫生设施的可持续发展目标(SDG)越来越难以实现。市政当局一直在试验一系列成本较低的卫生解决方案。简化污水处理系统(SSS)作为一种应对措施在不同的城市出现，但结果好坏参半。本文评估了坦桑尼亚达累斯萨拉姆一个非正式定居点的SSS项目。根据调查和焦点小组讨论相结合的方法，本文考察了SSS的社会和经济影响，并确定了未来城市卫生干预措施的一系列关键问题:可负担性、维护和治理。最后，我们考虑了对未来城市卫生研究和实践的影响，包括基于技术的方法的局限性以及关注当地居民多样化需求的必要性。

期刊介绍： Environment and Urbanization aims to provide an effective means for the exchange of research findings, ideas and information in the fields of human settlements and environment among researchers, activists and non-governmental organizations (NGOs) in low- and middle-income nations and between these and researchers, international agency staff, students and teachers in high-income nations. Most of the papers it publishes are written by authors from Africa, Asia and Latin America. Papers may be submitted in French, Spanish or Portuguese, as well as English - and if accepted for publication, the journal arranges for their translation into English. The journal is also unusual in the proportion of its papers that are written by practitioners.
