many thanks for your suggestions.

We have created two new versions based on the pictures of the SuSanA flyer. We have also incorporated one of the pictures from the SuSanA meetings (the 20th meeting in Dakar). I liked that idea!

One version still has an UDDT. As it comes along with other pictures, I don't have the feeling that it reinforces the messages that SuSanA stands for EcoSan only, but I am happy to hear some feedback from others!

How do you like the selected pictures?

Best regards,

(on behalf of the SuSanA Secretariat)

Re: The project database on the SuSanA website - please help us to review and update the filter options - by: muench
Thanks a lot for your helpful comments about the filter options in the SuSanA project database. I will respond to them below.

Dear all!

By the way, we now have over 300 projects in the database, check it out here:

If you work for an organisation which is a SuSanA partner, how about adding your favorite projects into the project database? It is fast and easy for anyone who is part of a SuSanA partner organisation. If you don't know if your organisation is a partner or not, just check here:

This welcome package explains to you what you can do when you're a SuSanA partner:

Coming back to Sterenn's suggestions: she was referring to the project entry mask which looks like this when you are entering projects to the database (sorry, I have tried but I can't seem to get a clearer screenshot to insert here):

She said:

• I really like that the projects can be connected to Working Groups. I feel like there might be a lot of overlap with the "field of activity" and "working group" which could get confusing?

Yes, indeed, I am also not satisfied with that. How could we resolve this? Our problem was that some of the "fields of activity" don't exist as a working group.

• I found the tab “Resource projects” a bit confusing. Is it asking what part of the sanitation system you are working on, and also includes the enabling environment? I think it would help to have it in the order of the sanitation system (on-site sanitation, transport, treatment, etc.)

Yes, the title in the filter is a bit odd. Later for the user we have called it "Filter by kind of project" and we give the following choices:

- Resource recovery
- Processing technologies
- User interface
- Faecal sludge transport
- Enabling environment and others

It was meant to indicate in which area the project has its focus. These areas were set up with the Gates Foundation projects in mind (it was their projects which started the database), but this could be changed. A starting point could be to rename it to "Project focus area".

• I like that there is the general option of “FSM” under technology. I feel like the technology options could be more categorized. I would find it easier if they were sorted by on-site sanitation technologies, emptying and transportation technologies, treatment technologies and reuse options ? For example, you could select that you are generally working on treatment technologies and below that category there are more specific options of treatment technologies that you could select (e.g., drying beds, sedimentation tank, etc.).

We don't have the capability of doing double-filtering like you suggested. Also I wouldn't want to drill too deeply with the filters. Keep in mind that people can also use keyword searched for e.g. "sedimentation tank". Are there any broad technology options that are currently sorely missing?

• I would then remove "Filter by reuse" which seemed very specific compared to other categories.

It's true it's a bit specific but on the other hand, SuSanA has traditionally had a focus on reuse and some people some to us particularly for that reason. So it's handy for them to be able to filter by different reuse options.

• Filter by audience was a bit unclear to me. Is it the target audience of the project or who you are uploading the project for?

It is meant to be the audience of the project. How can we make it clearer? In the project entry mask we called it "Materials for".

I hope that more and more SuSanA partners will start to enter their projects, and then provide us feedback what is not clear during the data entering process. So please continue to provide your feedback and we'll consider it and try to improve it.

Introducing 3ie from India: A new partner organisation of SuSanA - by: secretariat 3ieimpact.jpg

We would like to welcome 3ie from India as a new SuSanA partner organisation!

The following text is taken from their application form and was written by the partner organisation themselves.

Description and Activities in Sustainable Sanitation:

3ie funds impact evaluations and systematic reviews that generate evidence on what works in development programmes and why.

3ie is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding and producing high-quality evidence of what works, how, why and at what cost in international development. We believe that better and policy-relevant evidence will make development more effective and improve peoplea??s lives.

Since its founding in 2008, 3ie has awarded over 200 grants (146 impact evaluations, 33 systematic reviews and 38 other studies) in over 50 countries, with a total value of US$ 84,225,205.

3ie has offices in New Delhi, London and Washington, DC. The three main funders of 3ie are the Bill & Melinda Gates Foundation, UKaid through the Department for International Development and the William and Flora Hewlett Foundation.

3ie manages two sanitation-related thematic windows; one funded by the Water Supply and Sanitation Collaborative Council, and another funded by the Bill & Melinda Gates Foundation. The former aims to generate evidence on the psychosocial effects of sanitation, and the latter, promoting latrine use in rural India.

Climate Change Impact on Water Well- Latrine Distance - by: KimAndersson Regarding your call for SuSanA to develop guidance manuals on impacts of climate change on sanitation and water supply facilities; I just want to inform you that SuSanA WG3 (Renewable energies and climate change) is leading a paper on linkages between sanitation and climate change. This aims at providing some general guidance on how sanitation can help address climate change. The initial drafting of this paper has been supported by the SuSanA Phase III project and by a group of students from the Cranfield University. Later this year I expect that the draft paper will be shared on the forum to receive comments and feedback from Forum members.

I can also recommend having a look at the factsheet from WG3 'Links between sanitation, climate change and renewable energies' that provides some useful orientation.

All the best,

What we have done so far in WG7 around MHM - by: muench
Thanks for posting this information (would it have a higher readership if this thread was placed in the sub-category on MHM? Maybe. If you think yes, we could move it to there).

To give it more attention, I wanted to point out that in the publication that you mentioned, the following four cases deal with MHM:

Case 5 India, Kenya, Bangladesh - Raising Awareness on Menstrual Hygiene Management / WASH United
Case 6 Uganda - Promotion of Locally Made Washable Pads / Days for Girls
Case 7 Tajikistan - Ecological Sanitation for Rural Tajikistan / ASDP Nau & WECF
Case 8 Kenya - Menstrual Cup Distribution and Health Education Program / Ruby Cup & Golden Girls Foundation

Secondly, I was wondering which wiki page you are referring to when you said:

or you find them in the SuSanA Wiki searching for MHM


Even though I know the SuSanA website like the back of my hand, I had trouble finding that.

I found this section (but only after logging in), is this the part that you meant?:,_rural_and_schools_(with_gender_and_social_aspects)

I only found it via going to , then Resources, and then Akvo Sanitation Portal and then logging in, but this doesn't seem the right way of getting there.

Assist NGO's & Municipal entities in developing sustainable Operation & Maintenance Plans for Rural sanitation - by: WayneB
Firstly, I would like to introduce myself, I am Wayne Birkholtz, Rural Water and Sanitation Specialist dealing in on-site disposal methods. I was a key member of a pilot project that received foreign funding to develop a “franchise” based approach to the O & M of sanitation at schools and municipalities. I have approximately 10-15 years of experience in the sanitation sector, and have assimilated a vast amount of information, as to what works and what does not work!
Should there be any NGO’s or municipal services that require assistance with the different forms of sanitation that they are using, or advice, please feel free to contact me.

Best Regards

Clearing trash from pit latrines-A new device - by: dandreatta
Their solution was to use two devices, one for the trash and one for the more liquid contents. I don't think their liquid content device is ready to share yet, but I really like their trash pickup device. They call it "the crabtrap" because it looks like something you could also use for fishing for crabs, and I suppose you could with the right bait. A link to a youtube video is below, and I attach a few still photos to get people interested.

This device picks up bottles and similar objects, as well as just about any other kind of trash. I would have to think that the current "fishing" devices used to clear trash from pits work well on bags and rags but have great difficulty in picking up certain types of trash, such as bottles. Reportedly, such fishing devices are very dirty, particularly when getting the trash off the hooks.

The device you see here is a prototype, the final device would need to be more rugged and have some other small design changes. A finer screen might be an improvement to keep the condoms and small trash in the crabtrap. I told the students to assume the smallest possible squatting hole, a keyhole of 10 by 18 cm. Squatting holes that were even a little larger would allow a larger device which would be easier and faster than seen in the video. The size of the device could be set to match the smallest squatting hole locally. Some recent postings from Chiposa, Holm, et. al, suggest that squatting holes are usually much larger than seen here, at least in Malawi.

Public cassete dry toilet in Kiev - by: Ecowaters Don't let the crates fill too high or they will be very heavy to remove, even after composting, I know this from experience.
I suspect this system will emanate odor.
Worms do not like the ammonia (or something else) of urine, but if they can get away from it, it can work.
I imagine you'll want a more enclosed system with a leachate drain.
I would install active ventilation.
Let us know how it's working in one year.]]>

What can we reliably say about pathogen removal with vermifilters? - by: muench

Hi Elisabeth,

I think the first thing to make clear is that we do not see the main purpose of the Tiger Toilet to be the production of compost for use on soil. In fact we have deliberately tried to minimise production of vermicompost so as to reduce the amount of maintenance for the user. Our current estimates are that it will be 8-10 years before any removal of vermicompost is necessary and the amounts involved will be quite small and not very useful to a farmer. Our oldest systems are over three years old and have not yet been emptied. The whole purpose of the Tiger Toilet is to provide safe, effective and low maintenance treatment of faecal waste for low income households ….we are not promoting re-use with this system.

We agree that there could be helminths present in the vermicompost and therefore would not advise using it as a soil conditioner without some kind of further treatment.

Kind regards,

Developing Markets for Sanitation: A Blog Series - by: campbelldb Sanitation Updates .

Developing Markets for Sanitation: A Blog Series

In response to the growing prevalence of market-based approaches to sanitation, the Bill & Melinda Gates Foundation convened a meeting between three leading sanitation development practitioners—iDE, PSI, and Water for People—to discuss their experiences in building supply capacity and demand for sanitation products and services, and possibly develop a joint understanding of the process. The result of those discussions are presented in this four-part blog series.

Public cassete dry toilet in Kiev - by: BPopov
No, this is no-flush direct drop system. We will try with worms and see how it works. I haven't try to use the worms before but I know that others succesufully used them in the dry toilets.

Directing hand-washing grey water might be a good idea if we will need to do so in terms of flushing the urine our of crates a bit . However I'd keep the total effluent volume to the minimum or put a secondary filter down below before the soil infiltration.]]>

How do you get households to connect to existing sewer networks? - by: issantos
Connections are called regular when the following four conditions are identified, according to Brazil's national and local legislation:

1 - Sewage effluents are being layed in public sewage system;
2 - Rainwater is not been layed in public sewage system;
3 - Household is not using a septic tank;
4 - Household has a grease tank (trap) according to standards established in technical norms.

Whenever any of these situations above is not identifyed by the agents, it is considered irregular. Once notified, users have two weeks to resolve it. In case they don’t, municipal environmental agencies take other measures (notification) related to their responsibilities. No fees are established.

I'd be glad to know the results of your review. Thank you]]>

Sphere revisions; The deadline is looming! - by: jonpar
Attached are the 2 standards that are probably of most relevance to SuSanA community; namely :

i) Excreta management standards; and
ii) WASH Hygiene standards

There are also other standards that many of us will be interested to review related to:

i) Vector control, solid waste management, water supply, and drainage; as well as
ii) Standards on WASH and nutrition, and WASH and health.

You will see the overall layout of the standards in the diagram in the file : "Changes in WASH standards" which compares the proposed standards with the previous ones.

Overall there is a lot to review but when broken down like this, there is not so much if we choose just to focus on 1 or a couple of standards to scrutinise.

Also attached is the information about the review process and the feedback form.

I am hopeful that those of us who are working in the humanitarian sector with a focus on disaster risk reduction, emergency preparedness and response, will find to review and submit comments in the next few days.

The alternative is for members of the working group on Emergencies and Reconstruction Situations (WG8) to put forward their comments on the Forum to allow for some discussion prior to submission.

best regards,

A public urinal for women that is also a beautiful flowering garden - by: canaday
Thank you for these questions, which I will answer below and hopefully resolve any doubts.

1) Would location be a problem?. How far would this women's urinal have to be from for instance a restaurant or a bus terminal?

It could be right next to a restaurant or in an open space within a bus station, since there would be no smell and there just has to be enough room for the plants that form the privacy walls. If hedges are used, more space would be needed than trellises with vines.

2) What about smell from this urinal when the weather is inclement or overcast?

There would be no smell in any weather, since the urine goes down a hose to the bottom of the tank, and the air that comes out of the tank has to filter through the soil of the flower planter, which would absorb any smell. In addition, since there is no roof, the wind would quickly whisk away any minor odors. Furthermore, Nadia Andreev, in Moldova, is working out ways to do fermentation with lactic acid bacteria in such urine tanks, which would acidify the urine and prevent the formation of smelly ammonia, which also makes it better fertilizer for plants (and more pleasant to spread on fields).

3) Where are they going to wash their hands (as women usually wipe themselves after urinating)?

There is a TippyTap in the design for handwashing and the water would sprinkle the plants in the flower planter. If there is running water, a pedal-operated valve would release water in a similar way. Paper and sanitary pads would go into the trash bin, which could also be a larger duct, in sites with lots of visitation.

4) Would Wurinatus attract male sex offenders?

No, this is actually one of the advantages of this design, since they can be located in highly visible, public places, and women would not have to go farther away from safe zones in order to find sufficient privacy. In fact, they could placed right next to homes, schools, businesses, bus stations, busy avenues, shopping centers, etc. Where possible, they could be located in clear view of places where guards and police stand (without being right next to them). These should be safer than conventional restrooms, since passersby and police can easily hear if there are unusual sounds coming from within.

5) Could you give more details on the Uritrottoir male urinal for sidewalks?

This was designed by the Faltazi company in France. It has a beautiful flower planter on top, while below there is a box of wheat straw or sawdust that absorbs the urine and is periodically taken to a composting facility. I would suggest that we could do something similar to the Wurinatu for men, only it would be simpler. Here is a very simple model:

Please let me know what you think ... and if you want help to make a Wurinatu.

Best wishes,
Chris Canaday]]>
