Environmental determinants of access to shared sanitation in informal settlements: a cross-sectional study in Abidjan and Nairobi

Jérôme Chenal, Vitor Pessoa Colombo, Jürg Utzinger

Background Universal access to basic sanitation remains a global challenge, particularly in low- and middle-income countries. Efforts are underway to improve access to sanitation in informal settlements, often through shared facilities. However, access to ...

Water and sanitation hub in Mali. Reasons for an architecture seminar

Riccardo Vannucci

What is the goal of a five-day seminar for the (architectural) design of a ‘water and sanitation hub’ in Mali? What does one want to achieve, or rather, what is the seminar meant to ‘disseminate’? To begin with, what is a ‘water and sanitation hub’? It is ...

Modelling quantities and qualities (Q&Q) of faecal sludge in Hanoi, Vietnam and Kampala, Uganda for improved management solutions

Magalie Diane Bassan, Linda Strande, Amédé Ferré

The importance of faecal sludge management is gaining recognition. However, methods are still lacking to reasonably estimate the quantities and qualities (Q&Q) that need to be managed, which makes the planning for and implementing of management solutions q ...

Safely Managed Hygiene: A Risk-Based Assessment of Handwashing Water Quality

Matthew Eric Verbyla, Timothy R. Julian

Sustainable Development Goal (SDG) Indicator 6.2.1 requires household handwashing facilities to have soap and water, but there are no guidelines for handwashing water quality. In contrast, drinking water quality guidelines are defined: water must be "free ...

High time-resolution simulation of E. coli on hands reveals large variation in microbial exposures amongst Vietnamese farmers using human excreta for agriculture

Ana Karina Pitol Garcia, Timothy R. Julian

Infectious disease transmission is frequently mediated by the environment, where people's movements through and interactions with the environment dictate risks of infection and/or illness. Capturing these interactions, and quantifying their importance, off ...

Virus inactivation in stored human urine, sludge and animal manure under typical conditions of storage or mesophilic anaerobic digestion

Tamar Kohn, Loïc Decrey

Viruses represent major disease transmitting agents carried by human excreta and animal manure. Understanding virus inactivation is therefore essential in preventing microbial spread due to inadequate treatment of these materials. Here, we investigated the ...

Reaction extents: A Divide-and-Conquer Approach for Kinetic Model Identification

Dominique Bonvin, Julien Léo Billeter

Obtaining reliable wastewater treatment process models is critical for the application of model-based design, operation, and automation. For example, Masic et al. (2014) explored the use of an observer designed for nonlinear processes to estimate nitrite i ...

Ammonia as an in-situ sanitizer: influence of virus genome type on inactivation

Tamar Kohn, Loïc Decrey, Shinobu Kazama

Treatment of human excreta and animal manure (HEAM) is key in controlling the spread of persistent enteric pathogens such as viruses. The extent of virus inactivation during HEAM storage and treatment appeared to vary with virus genome type, though the rea ...

Technologies for the treatment of source-separated urine in the eThekwini Municipality

Tamar Kohn, Linda Strande, Kai Udert, Bastian Etter

In recent years, a large number of urine-diverting dehydration toilets (UDDTs) have been installed in eThekwini to ensure access to adequate sanitation. The initial purpose of these toilets was to facilitate faeces drying, while the urine was diverted into ...

Virus inactivation mechanisms in human urine and fecal sludge

Loïc Decrey

Water, sanitation and hygiene interventions are among the most significant health interventions addressing the worldwide burden of diarrheal disease and environmental enteropathy. Sanitizing human excreta and animal manure (HEAM) is a critical step in redu ...
