ABSTRACT Slum populations are commonly characterized as having poorly developed water and sanitation systems and may access services through informal channels. However, there are limited representative profiles of water and sanitation services in slums, making it difficult to prioritize interventions that will make services safer for residents. This cross-sectional study examines the quality of and access to water and sanitation services in government-defined slums across Dhaka, Bangladesh. Access is generally high but is subject to quality issues related to safety, reliability and liability. Services are often operated by informal middlemen at various stages of provision.

达卡贫民窟的水和卫生设施：服务提供的可及性、质量和非正规性

摘要 贫民窟人口的普遍特征是供水和卫生系统不发达，可能通过非正式渠道获得服务。然而，贫民窟的供水和卫生服务的代表性资料有限，因此很难优先考虑使居民的服务更安全的干预措施。这项横断面研究调查了孟加拉国达卡政府定义的贫民窟的供水和卫生服务的质量和获取情况。访问率通常很高，但会受到与安全性、可靠性和责任相关的质量问题的影响。服务通常在提供的不同阶段由非正式中间人经营。
