Thank you so much for your comprehensive explanation , I am very interested in water recycled and reusing on bio remediation and wetland based but I am laboratory technologist as well as I teach material safety data sheet(MSDS) to university students (B.Sc.M.Sc and (Ph.D)
yes you work on grey water ,but today kitchen washing(Dish washing) and laundry washing manufacturers widely use of Enzyme and other strong chemical in their formulation which I wrote in my last mail are not biodegradable I believe for any waste water treatment in addition pathogen bio hazard ,chemical hazards determination must be lunched because their risk are higher(long term) than bacteria pathogen(short term) which I believe they will removed with considering growth log (limitation of nutrients ,competition with aerobic non pathogen bacteria) in water dam and wetland.
and yes the water dam is being to used for irrigations but we face with ecosystem chain ,Plants ,human being and animal so we must be assured of (integrated) total safety in waste water treatment although I am sure dam process reduces chemical hazard but in how extend?
In conclusion I congratulate you for your innovative design which I am very interested in it because of it wide applicable in water scarce region.
Thank you again for your mail.

pilot project on UDDTs and composting by GIZ in Benin - by: muench
Thanks a lot for informing us about your pilot project in Benin which has now come to an end and which involved 30 UDDTs (28 at household level and 2 at public level) and community-level composting.

I see that the SuSanA case study about this project and additional documents are now available here:

Dubois, A. (2014). Combined solid waste management and basic sanitation Lokossa, Mono region, Benin. Case study of sustainable sanitation projects. Sustainable Sanitation Alliance (SuSanA)

Some photos:

I really appreciate your openness, describing in detail in the case study all the problems and delays that you faced.

For example, you wrote:
Early withdrawal of the GIZ coordination team

The GIZ field coordination is due to be over in mid-August
2014, which is only 7 months after the launch of the
composting plant activities. Even though the departure of the
GIZ team has been postponed as much as possible (because
of the delays accumulated during the project implementation)
the withdrawal will come at an early stage. This may impact
the effective operation of the activities and therefore
jeopardize the sustainability of the project. The project’s
partners (especially the city council) are meant to take over
the GIZ coordination and monitoring activities, however it has
been observed during the temporary absence of the GIZ
coordination team in April and June 2014 that their
involvement was below expectations and that the group of
gardeners was more or less left on its own. Therefore a focus
is currently given on finding new partners who could in one
way or another support the project activities.

If we ask you questions on the forum now, please don't take this as criticism in any sort, it is just about learning from your work (it is always so easy to criticise what other people have done, but doing it better oneself is more difficult!).

You mentioned in the case study:

A year later (October 2013), after an evaluation of the
implemented activities and the potential of the project, BMZ
has assigned an additional budget to scale up the project,
which has led to a reinforcement of activities.

My questions:

What sort of up-scaling plans did you have or do you have?

What would be the best case scenario for the future of this kind of work in this city?

What would be the worst case scenario?

If things were to fall into disrepair, where do you see the biggest risks? In the UDDTs no longer being used? Or in the UDDTs only being used until they are full? Or the faecal matter being taken out but not composted safely?

Are UDDTs becoming quite common in Benin, like in other countries in the region (e.g. Burkina Faso)? What about composting, is it quite well known in Benin?

I am very impressed with the level of documentation you have done for this project and encourage anyone to browse through the various documents available in your post above or here:

Thanks a lot for telling us about this interesting project.

Re: A grey water dam for the treatment and reuse of grey water for single and multiple households - by: Ababu
Thank you for your interest in the grey water dam. Yes quality and characterizing the possible health risk is part of our research concern. We believe the grey water dam set up provides a better barrier against pathogen compared to the vertical grey water tower because the grey water tends to get soaked up in the vertical grey water tower from my experience. We are not including fecal and urine wastes in the dam. We are using grey water. We do not therefore anticipate heavy metals, pesticides, urine products such as endocrine disruptor, hormones, etc as some thing to worry about assuming of course grey water that is being used in the grey water dam comes from the kitchen, baths and washing and some control is exercised although cross contamination is possible. The effect of BOD/TOC is indirect in the sense that bacterial count may increase with availability of organic matter in grey water. However, there are not many documented cases of effects of chemicals on grown plants from grey water application although i do not mean to discount that. How much of these chemicals ends up in the plants is another question because the risk is in eating the plants unlike drinking water and this risk might be low because plants do have barriers. While some control on what should be taken to the dam is necessary and while pretreatment might be considered to improve the water quality going into the grey water dam, we, however, think that our main concern in relation to the grey water dam should be pathogen risk (bacteria, virus, protozoa and helminth) because grey water might contain pathogen although to a lesser degree compared to fecal waste. The grey water dam can be considered as a form of restricted irrigation and the WHO guideline of achieving 3-4 log reduction of E.coli ( 99.9 and 99.99% removal)within the soil in addition to <1 helminh/egg per 100gm of soil with an infection risk of 1 in 1000 might be the appropriate guideline to apply. The most probable risk is in our case direct ingestion of the soil containing pathogens in the course of dealing with harvesting plants and maintenance or contamination of plants by the soil and here proper hygiene also plays a role. There are reports of 2-7 log removal of ecoli by soil depending on how fine the soil is and in this connection we would like to see how the mixture of ash, manure and fine/coarse mixture we used fares in terms of pathogen removal.There is a need to establish the effectiveness of the grey water dam soil as a pathogen barrier.]]>

Re: faecal transplants - by: Carol McCreary Mother Jones magazine is an article on the current regulatory environment for fecal transplants for C diff [Clostridium difficile] in the US and likely developments at the federal level.

Should We Regulate Poop As a Drug? The future of fecal transplants, and a bevy of entrepreneurs, hinges on how the FDA decides to regulate the

There is definitely progress in this area. Last year the National Institutes of Health (NIH) and the federal Food and Drug Agency (FDA) agreed physicians could perform the procedure albeit with lots of permissions and paperwork. Alternately, two companies have proposed pre-packaed and stabilized enemas, that are currently undergoing clinical trials with the. But is approval as a drug appropriate for something like feces, which varies so radically from person to person?

A few weeks after the meeting at NIH, the FDA changed its approach. Fecal transplants would still be regulated as a drug, but to keep them moving (at least until a treatment was finally approved), the agency said it would exercise "enforcement discretion"—meaning health care providers could go on administering transplants for recurrent C. diff patients without filing paperwork for new drugs.

In February 2014, the FDA issued a second draft of its guidelines. The Infectious Diseases Society of America, a 10,000-member organization of doctors and scientists, offered a blanket endorsement of the FDA's position.]]>

Re: SanMark-CITY: Intelligent Design in Urban Sanitation Marketing- quick glimpse - by: JKMakowka
I am just a bit concerned that the choice of technology options will limit the analytical outcome of this; it looks like it will be a case of comparing apples with oranges as the systems are so different in their method of operation, costs and level of development.

For example the tiger-toilet is (as far as I know) still quite early in development and only a hand full of working examples exist. The functioning principle of the Enbiolet seems to be based on what is also sold microbial pit-additives and sanitation expert opinion is that this is largely a scam (i.e. no need to empty is unrealistic). I can't really comment on the biofil as too little info is given, but the Sun-Mar seems way out of reach in regards to affordability for the targeted Bangladeshi urban slum inhabitant.]]>

Re: WASH and Nut research project: Impact of Household WASH package to nutrition program in Chad. - by: JKMakowka
It might not actually show a lower prevalence of diarrhea though as those on/off heavy events are often caused by other reasons than polluted water, and hygiene is never perfect.

For water treatment you seem to be planning to use chlorine tablets or a combined product like PUR? Have these been pre-tested for acceptability (smell and taste of chlorine) and effectiveness (not too high turbidity)?]]>

WASH and Nut research project: Impact of Household WASH package to nutrition program in Chad. - by: carlottadenis
I would like to inform you about a research project Action contre la Faim (ACF) will be conducting in the next months, called Benefits of a household WASH package to Community Management of Acute Malnutrition (CMAM) program in Chad.

The ‘WASH in Nut’ strategy for Sahel led to the introduction of a list of specific WASH activities for CMAM beneficiaries aiming at protecting malnourished children against worsening of their nutritional status, and potential relapses caused by WASH related infections. ACF now considers crucial to evaluate the effect of this package in a Sahelian context characterized by high prevalence of severe acute malnutrition, through a research project.

This research project will start in September, 2014 in the Kanem region in Chad, where ACF is already intervening in WASH and Nutrition. It will consist in assessing the benefit of adding a “home WASH package” (water treatment and hygiene kit + hygiene promotion) to nutritional rehabilitation of children under 5 suffering from Severe Acute Malnutrition (SAM) without medical complications receiving OTP (Outpatient Therapeutic Program) treatment.

The study design is a Randomized Controlled Trial with a total of 2500 children in 10 different areas: 50% in the control group (receiving OTP treatment) and 50% in the intervention group (receiving OTP treatment + the household WASH package).

Household Wash package is composed of a household water treatment and hygiene kit (water container, water disinfection consumables, soap, cup, hygiene promotion leaflet), hygiene promotion sessions to the child caregiver at health center level (hygiene kit and water treatment demonstrations, hygiene related care practices messages), and a household visit during the treatment (inclusing a hygiene refresh training).

3 hypotheses will guide the study:

1) Children affected by Severe Acute Malnutrition receiving OTP treatment and benefiting from a “home WASH package” have a lower prevalence of diarrhea during the course of their treatment.

2) They have better outcomes in terms of weight gain during treatment.

3) They are less at risk of relapse after successful treatment.

Please do not hesitate to share your comments on this study or to share other similar studies you might know about.

Re: SanMark-CITY: Intelligent Design in Urban Sanitation Marketing- quick glimpse - by: esthapit
Title of grant: SanMark-CITY
• Subtitle: SanMark-CITY: Intelligent Design in Urban Sanitation Marketing - Fostering Adaptation and Evolution
• Name of lead organization: ICCO Cooperation
• Primary contact at lead organization: Leonard Zijlstra
• Grantee location: The Netherlands
• Developing country where the research is being or will be tested: Bangladesh

Short description of the project:

The Water and Sanitation Program (WSP) report 2012 of the World Bank highlights the continuing corrosive effect that poor sanitation and public health has on the Bangladeshi economy. Health-related losses are estimated at over 4 billion dollars, the equivalent of 5% of GDP. (Economic Impacts of Inadequate Sanitation in Bangladesh, WSP 2012), and human waste still drives forty-nine distinct disease vectors throughout Bangladesh.

Most of the existing sanitation interventions in Bangladesh have been based on pit latrines and septic tanks. It appears that some households were offered little choice in terms of the type of system that was installed. Neither of these technologies are particularly sustainable from a technical point of view in the absence of good faecal sludge management systems. A survey of several sanitation projects in 2010 showed that in many cases pit filling and operation and maintenance were concerns for households. Further, in crowded slum areas there may not be sufficient space to install latrines and service their emptying. This report highlighted the lack of sustainable sanitation options for slum areas, and high-water table and flood-prone districts.

Technology and business driven solutions have a major role to play in helping to deliver better sanitation for the poor in Bangladesh. This project includes to explore the potential of four toilet technologies to overcome some of the challenges faced in delivering a sustainable impact on this problem. It takes a market-led approach, and will focus on the role of the private sector to develop commercial ventures which are sustainable and scalable as the implementation vehicles. In line with lessons learned about inclusive innovation, it recognises that development and implementation requires collaboration with a number of partners including NGOs, research organizations, government authorities, and building on existing service providers.

Drawing on its growing thought leadership in combining sanitation technology, ICCO Cooperation along with two other implementing partners i.e. International Development Enterprises (iDE) and Dushtha Shasthya Kendra (DSK) proposes to “adapt and evolve” four promising SanTechs similar to those developed through the Gates Foundation’s Reinvent the Toilet Challenges (RTTC) and Grand Challenges Explorations (GCE) to the realities and market systems of urban Bangladesh through the “Sanitation Marketing for Urban Onsite Sanitation in Bangladesh”, or “SanMark-CITY” project.

SanMark-CITY will explore critical gap that currently exist in introducing, adapting, and sustaining affordable sanitation technologies at scale for slums in urban Bangladesh and will inform key stakeholders in the public, private and nongovernmental sectors on how best to support the diffusion of such technologies for maximum impact.

The project has four objectives and through achieving these objectives, it would be possible to provide alternative toilet options to the poor slum dwellers of Bangladesh, which are affordable, environmentally sound, hygienic and approved by the institutes like Bangladesh University of Engineering and Technology (BUET) and Department of Public Health Engineering (DPHE). Through the business promotion interventions of the project, tested and approved toilets would be easily available in the market, which will enable the slum dwellers to get access to those. Besides, through direct involvement of DPHE in the project, it would be possible to make the toilets available at the Municipality level throughout the country in future.


The overall objective of the SanMark-CITY project is to successfully adapt and develop commercialization channels for 4 improved on-site sanitation technologies for urban areas of Bangladesh.

These sanitation technologies are (for details see flyer in post above):


1. To test four selected toilet technologies and localize design to demonstrate their potential to meet the sanitation needs of urban poor communities in Bangladesh in sustainable, affordable way
2. To develop business model of viable toilet technologies
3. To explore and identify the commercial capacity and supply chain in Bangladesh to meet the demands of consumers, suppliers and large-scale sanitation programs
4. To facilitate knowledge management, dissemination and roll-out on a large scale

Start and end date: 1 January 2014 and 30 June 2015

Grant type: Global Development Grant Number OPP1097054

Size: USD 699,587

Research or implementation partners: International Development Enterprises (iDE) and Dushtha Shasthya Kendra (DSK)
