The global sanitation workforce bridges the gap between sanitation infrastructure and the provision of sanitation services. Sanitation workers provide an essential public service but often at the cost of their dignity, safety, health, and living conditions. They are some of the most vulnerable workers. They are far too often invisible, unquantified, and ostracized, and many of the challenges they face stem from this fundamental lack of acknowledgment. Sanitation workers are exposed to serious occupational and environmental health hazards risking illness, injury, and death. This report presents the findings of a study that examined nine case studies of sanitation workers in low- and middle-income countries, predominantly focusing on emptying pits and tanks, providing transportation of fecal sludge, and performing sewer maintenance. It is an initial analysis into a growing body of work on sanitation workers, but already the findings highlight several action areas to ensure that efforts in reaching Sustainable Development Goals (SDG) 6.2 and 6.3 do not compromise the dignity, health, and rights of the workforce. Collecting data from literature and key informant interviews, the nine cases provide an overview of the key challenges sanitation workers face. The report also addresses good practices and suggests areas for action.

This report focused on a numerical modelling assessment of the possible effects of greywater reuse on the freshwater lenses in South Tarawa, Kiribati. Conceptual models and 2D cross-sectional numerical models of selected transects of Betio, Bairiki and Bikenibeu Islands were developed based on available field data. Simulations then were used to assess greywater transport and its effects on freshwater lenses in current situation and future scenarios. The modelling results show that adding the greywater discharge increases notably the freshwater thickness compared to the baseline scenario where greywater discharge is neglected. Eight scenarios were simulated to test the influence of rainfall dynamics and groundwater abstraction rates on the contribution of greywater disposal on freshwater lens thickness. The report then provides recommendations for future work to enhance the outcomes of future modelling efforts and the feasibility of indirect greywater reuse.

Lose yourself in the vast sewer networks that lie beneath the world's great cities - past and present. Let detailed archival plans, maps and photographs guide you through these subterranean labyrinths - previously accessible only to their builders, engineers and, perhaps, the odd rogue explorer. This execrable exploration traces the evolution of waste management from the ingenious infra-structures of the ancient world to the seeping cesspits and festering open sewers of the medieval period. It investigates and celebrates the work of the civil engineers whose pioneering integrated sewer systems brought to a close the devastating cholera epidemics of the mid-19th century and continue to serve a vastly increased population today. And let's not forget those giant fatbergs clogging our underground arteries, or the storm-surge super-structures of tomorrow.

Poor sanitation and hygiene practices remain a significant challenge for Cambodia. The purpose of this study is based on a request of the Ministry of Rural Development (MRD) to identify the behavior change gap as illustrated in fecal sludge management (FSM) in rural areas theory of change. Thus, the main purpose of this research study is to understand current practices of pit emptying and sludge reuse in the rural context of Cambodia and to find drivers and barriers of these pit emptying and sludge usage behaviors. The study is designed with a purpose to track the aspirations, motivations, and barriers impacting such practices in the rural context. Findings from this study is to produce a set of recommendations that can be an informed choice for the MRD to design a rural FSM national guideline. The findings from this study will also provide a key input for water, sanitation, and hygiene (WASH) sector of Cambodia with a comprehensive information and analysis as a catalyst to understand the views of FSM behaviors and practices from stakeholders, individual households, and private sectors for developing innovative solutions to address issues of FMS management and practice in the rural context.
