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 ...

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 ...

Two-Dimensional Numerical Simulation of Bed-Load Transport of a Finite-Depth Sediment Layer: Applications to Channel Flushing

Carmelo Juez Jiménez

Numerical modeling of bed-load transport in shallow flows, particularly oriented toward environmental flows, is an active field of research. Nevertheless, other possible applications exist. In particular, bed-load transport phenomena are relevant in urban ...

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 ...

Pathogens and pharmaceuticals in source-separated urine in eThekwini, South Africa

Tamar Kohn, Linda Strande, Kai Udert, Christa McArdell

In eThekwini, South Africa, the production of agricultural fertilizers from human urine collected from urine-diverting dry toilets is being evaluated at a municipality scale as a way to help finance a decentralized, dry sanitation system. The present study ...

Reservoir sedimentation management at Gebidem Dam (Switzerland)

Tobias Meile

The Gebidem Dam located on the Massa River intercepts annually around 400’000 m3 of solid material. These sediments must be evacuated by annual flushing of the reservoir over 4 to 7 days. A trend for silting in the flushing channel was observed during the ...

Influence of geometry shape factor on trapping and flushing efficiencies

Anton Schleiss, Sameh Ahmad Kantoush

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped a ...

Temporal dynamics of antibiotics in wastewater treatment plant influent

David Andrew Barry, Luca Rossi, Sylvain Coutu, Htet Kyi Wynn, Vera Wyrsch

A yearlong field experimental campaign was conducted to reveal time scales over which antibiotic fluxes vary in the influent of a wastewater treatment plant (WTP). In particular, sampling was carried out to ascertain the amplitudes of monthly, daily and ho ...

Impact Load Measurements in an Erosive Cavitating Flow

Ayat Karimi, Jean-Pierre Franc

Impact load measurements were carried out in a high-speed cavitation loop by means of a conventional pressure sensor flush-mounted in the region of closure of the cavity where maximum damage was observed. The sensor was dynamically calibrated by the ball d ...
