Collaborative Bibliography on FSM in Humanitarian Situations

Dear Colleagues:

We have made a quick start on a FSM bibliography at the link below, and since such this is such an important topic, we hope to update it regularly with the latest research, news, studies, etc. Please contact us if have other studies and resources that should be added.

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.

WSUP – The bottom line: understanding the business of sanitation

This game was produced by Water & Sanitation for the Urban Poor (WSUP) as an exploration of some of the challenges around involving the private sector in sanitation service delivery in cities. wsup-logox2

In the fictional African city of Bafini, 80% of residents have no access to a sewer connection, relying instead on toilets with pits or septic tanks.

This creates a need for better faecal waste collection services, and a market opportunity for a smart entrepreneur.

You run a waste management business in Bafini, and have just decided to expand into faecal sludge management. You have a positive cash flow, which you will need to maintain.

Play the game.

We make fake poo in a laboratory – to improve sanitation in Bangladesh

We make fake poo in a laboratory – to improve sanitation in Bangladesh. Phys.org, July 12, 2017.

Across the world, almost three billion people do not have the luxury of a flushing toilet. Instead they rely on static sanitation systems, like pit latrines to deal with their waste. As these are not often connected to a sewer, they require manual emptying and disposal.

Poor understanding of the risks involved means that untreated sludge is often thrown into nearby fields and rivers. The impact of this can be devastating.

Yet is is estimated that every dollar invested in better sanitation returns up to US$5.50 in social and economic benefits. These come through increased productivity, reduced healthcare costs and prevention of illness and early death.

A crucial part of improving sanitation lies in researching and developing simpler, more efficient ways of treating sludge in places where a sewerage and centralised waste water treatment is not available.

My research is part of a partnership with the engineering firm Buro Happold (BH) who were asked by WaterAid Bangladesh to find a sludge treatment technology which was effective, practical and affordable.

After considering options which included biogas and pit additives – products used to try and reduce sludge volume – the company opted for unplanted drying beds. They are simple in design and make use of the reasonable amount of sunshine in Bangladesh.

4,900 days from now, in 2030, the Sustainable Development Goals will expire.  If that feels like a long time, consider the work ahead.  And by work, I dare not attempt to wrap my head around all 17 goals; I refer specifically to the WASH goal – SDG #6 – and even more specifically to the sanitation targets.

From my admittedly invested perch – I run a sanitation company – the most exciting thing about transitioning from the MDGs to the SDGs is the belated inclusion of treatment.  There’s finally recognition that “improved sanitation” without treatment is not improved sanitation.  The WASH community’s new mandate: “halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally” (SDG 6.3).  But consider that the urban population still requiring “safely managed sanitation” today stands at 3.214 billion [1]. Serving them entails expanding safe management, i.e., some form of treatment, to 625,000 people each day for the next 4,900 days.  That’s basically a city a day.

How can we achieve such a massive expansion of safe fecal sludge and wastewater management?  For starters, let’s stop building treatment plants. Heresy? There’s a better way.

The Ifakara Health Institute (I.H.I) in collaboration with Bremen Overseas Research Development Association (BORDA) in Tanzania, have come up with an innovative human waste treatment and management technology that finally makes human feces a risk-free resource for producing fuel and fertilizers. fecalsludge

The brains behind this human feces treatment project are Dr. Jacqueline Thomas and Mr. Emmanuel Mrimi from I.H.I and Ms. Jutta Camargo from BORDA. It is an innovation that has come at the right time, and badly needed by cities like Dar es Salaam and Nairobi. In a big way, this project promises a sanitation challenge solution Mathare valley and Dar es Salaam residents can benefit from.

“With the significant reduction of pathogenic microorganisms”, Mr. Mrimi reassures you, “the treated human waste is safe. Users of these products do not put their health on the line.” The innovative Decentralized Waste Water Treatment Solutions (DEWATS) project is treating human waste in three different areas in Dar es Salaam. The project is supported by a grant from Human Development Innovation Fund (HDIF) which is part of an overall investment in innovation in Tanzania by UK Aid.
