eSOS Toilet: An Answer To Kenya’s Sanitation Challenge

eSOS Toilet: An Answer To Kenya’s Sanitation Challenge. Interesting Engineering, January 3, 2018. esos

The smart sanitation solution provides the basic hygiene to those who need it the most.

In the time of emergencies or following a natural disaster, the availability of proper sanitation facilities is always a concern. Undeniably, poor sanitation can often kill as many people as the disaster itself.

This becomes a critical issue, particularly in the temporary camps during the recovery process. Temporary toilet facilities are also responsible for pathogens spreading through a high groundwater table or flooding.

To improve this situation, IHE Delft, the world’s largest international graduate water education facility located in the Netherlands, has developed an emergency Sanitation Operation System (eSOS).

It is a holistic, sustainable and affordable sanitation solution for countries like Kenya, where open defecation is still in practice and also during the aftermath of a disaster.

As a matter of fact, eSOS toilet had a successful test run in the Philippines and its second prototype will soon be tested in Nairobi, Kenya.

What is eSOS? Let’s Take A Deeper Look

Reinventing emergency toilet and treatment facilities, eSOS uses information and communication technology (ICT) to cut down the expenditure of the entire sanitation management chain.

These new and innovative toilet systems can enhance the life quality of the people in proper sanitation need and also reduces the health risks.

Desalination in humanitarian situations

Dear Colleagues:

We were asked to compile a bibliography on this topic and have set up a shared google document.

The search results were kind of disappointing so please let us know if you have other studies or resources to add and we will try to keep an ongoing bibliography of the latest studies on desalination.

We also received requests to prepare bibliographies on the role water utilities in humanitarian situations so that will be the topic of the next biweekly update. Just let us know of any other topics that you are interested in.

Where are the evidence gaps in the water, sanitation and hygiene sector? Evidence Matters, December 12, 2018.
Going forward, there is still a lot we don’t know and, beyond looking at new, innovative technologies, there are a few gaps (or opportunities) the sector needs to look at if we want to achieve the Sustainable Development Goals (SDGs): More studies on vulnerable populations: We found no studies that looked at (or even captured information on) people living with a disability. We found one rigorous impact evaluation focusing on people living with HIV, two on refugee camps, and one on people living through, or in the immediate aftermath, of a humanitarian crisis.

Fecal Sludge Management (FSM) in Humanitarian Situations – draft, November 30, 2018

News

Gates Foundation and Global Partners Announce Commitments to Advance Commercialization of Disruptive, Off-Grid Toilet Technologies. Gates Foundation, November 2018.
“This Expo showcases, for the first time, radically new, decentralized sanitation technologies and products that are business-ready,” said Bill Gates during the opening plenary of the Reinvented Toilet Expo. “It’s no longer a question of if we can reinvent the toilet and other sanitation systems. It’s a question of how quickly this new category of off-grid solutions will scale.”

Emergencies headlines from around the world. Oxfam, November 2018.
Bangladesh – Our industrial scale sewage treatment plant is open for business. It has the capacity to take 40 cubic metres of human waste per day (thus catering for 150,000 people),and is the largest ever such system to have been built in a refugee camp. Built to a German design it took seven months to construct, but the initial outlay will be more than paid back by the low operational and maintenance costs. It represents a big step forward in our ability to deal with fecal sludge in situ rather than carrying it away, and we expect to be replicating it in future crises.

Events
5th International Faecal Sludge Management Conference, February 17-22, 2019, Cape Town, South Africa – This conference will provide the opportunity for sector professionals, governments, policy-makers, utilities, development partners, investors, industries and service providers to coordinate, develop and share learning to provide affordable and workable solutions at scale. This conference will focus on practical solutions to sustainably manage the whole non-sewered sanitation service chain, covering the toilet, containment, emptying, transport, treatment and reuse, as an essential component of city-wide urban sanitation services.

FSM In Humanitarian Situations
Preparing to Be Unprepared: Decision Making and the Use of Guidance on Sanitation Systems and Faecal Sludge Management in the First Phase of Rapid-Onset Emergencies. HIF-Elrha, BORDA, WASTE and Solidarités International, March 2018.
The first section investigates and compiles what options have been proven for applications in the emergency context. The second section discusses the driving forces behind the decisions made on fecal sludge disposal in first phase emergencies at the field level.

Compendium of Sanitation Technologies in Emergencies. EAWAG, 2018.
This Compendium compiles a wide range of information on tried and tested technologies in a single document and gives a systematic overview of existing and emerging sanitation technologies. In addition, it gives concise information on key decision criteria for each technology, facilitating the combination of technologies to come up with full sanitation system solutions, all linked to relevant cross-cutting issues.

Development of a Field Laboratory for Monitoring of Fecal-Sludge Treatment Plants. Water, August 2018.
In urban humanitarian-aid operations, safe treatment of fecal sludge is highly important. While currently field-deployable fecal-sludge treatment plants are being developed, field-ready analytical equipment for process-control and public health monitoring is missing. Within the Microbial Sludge Quality project, a field laboratory was developed.

Chemical disinfectants. GWPP, November 2018.
Safe water, sanitation, and hygiene provision and promotion are critical elements of emergency response to ensure human safety, health, and dignity. Disinfectants, such as chlorine, are widely used in emergency response to treat water for drinking. However, excreta is rarely treated in emergencies; the current focus of response activities is to provide safe, clean, and private sanitation facilities. In this chapter, we provide a summary of knowledge on disinfection of excreta in emergencies and recommendations for future research.

A pilot-scale microwave technology for sludge sanitization and drying. Science of The Total Environment, December 2017.
Microwave-based technology is promising option for treatment of faecal sludge, septic sludge and waste activated sludge. It is rapid and efficient in sludge sanitization (pathogen reduction) and drying (volume reduction up to 96%).

Low-cost Bangladeshi innovation at Rohingya refugee camp saves lives. CGTN, March 2018. The organization experimented with a simple filtration system, through which fecal sludge is collected mechanically using suction pumps and discharged through a series of filtration chambers to separate liquids from solids.  “The effluent is finally treated by a natural process in a ‘constructed wetland’ through the roots of Canna indica plants. After a month, the digested sludge converts to become compost,” Jahan explained.

JOURNAL ARTICLES

Individual and Household Risk Factors for Symptomatic Cholera Infection: A Systematic Review and Meta-analysis. J Infect Dis, November 2018.
We identified potential risk factors for symptomatic cholera infection including environmental characteristics, socioeconomic factors, and intrinsic patient factors. Ultimately, a combination of interventional approaches targeting various groups with risk-adapted intensities may prove to be the optimal strategy for cholera control.

Global Cholera Epidemiology: Opportunities to Reduce the Burden of Cholera by 2030. The Journal of Infectious Diseases, September 2018.
While safe drinking water and advanced sanitation systems have made the Global North cholera-free for decades, the disease still affects 47 countries across the globe resulting in an estimated 2.86 million cases and 95,000 deaths per year worldwide.

Household Water Treatment and Cholera Control. J Infect Dis. 2018, Sept 2018.
Overall, a moderate quality of evidence suggests that HWT interventions reduce the burden of disease in cholera outbreaks and the risk of disease transmission. Appropriate training for users and community health worker follow-up are necessary for use. Barriers to uptake include taste and odor concerns, and facilitators include prior exposure, ease of use, and links to preexisting development programming.

Surprise (or not)! Toy-in-soap intervention increases handwashing among kids in emergency contexts

Surprise (or not)! Toy-in-soap intervention increases handwashing among kids in emergency contexts. FHI360 Research, October 2018.

There is nothing more satisfying in life, for me, than being able to say: I never thought of it that way. The most game-changing innovations can often have seemingly common sense solutions, and we see these solutions popping up everywhere in peer-reviewed literature. soap.png

One of those published solutions jumped out at me this week as I read a Crowd 360 blog post about innovative hand hygiene interventions to celebrate Global Handwashing Day. Researchers from LSHTM, Save the Children and their partners published new evidence showing toys inside soap can increase handwashing among kids in emergency humanitarian contexts.

Studies have examined handwashing with soap in a variety of ways over the years – with adults, with young kids, and with older kids; with health-based messages, with nudges, and with motivational messages; in school-settings, and in stable, non-emergency settings. The new toy-in-soap study, however, is the first evaluation of its kind. Here I summarize why the study is different, what the authors found and why those findings matter.
