Love the simple UDDT design at the links (am going to build out a few for the experience:) but I think it will need the inclusion of the "frills" - seat, privacy structure, etc - to make it more acceptable to users

Otherwise it looks like a temporary "thing" that I think permanent residents will balk at (even now, a lot of the trouble with UDDT's seems to be the perception of them being inferior to a flush sewer or septic tank toilet - again, the marketing needs to be better!)

Great concept though - cheap, easy to make, easy to manage, but people being people, marketing and packaging is what will get them to aspire to it (and therefore want it and use it)]]>

Thanks for posting this very important topic that needs much more attention. It would be great for someone to do a thesis to bring together all the numbers on this, but it is clear the UDDTs have much to offer. In the following text from my blog, I mention some of the factors involved.

The Dry Toilet as a Weapon to Fight
Global Climate Disruption

We are all becoming more and more aware that our world's climate is getting messed up. It is not raining when, where and how it should ... and it is all due to what the human species has done, burning petroleum, burning forests, grazing cattle, and defecating in the water.

You may not have known about that last one, but it is a bigger factor than you may think.
Urine-diverting Dry Toilets (www.ecosanres.org, www.susana.org) have much to offer:

--If we mix everything in water, it ferments in the absence of oxygen and produces large amounts of Methane (Greenhouse Gas #2).
--The urine goes as straight as possible to the soil as fertilizer, thus keeping the feces drier and these also get covered in an absorbant dry material, like soil or wood ash. Some CO2 is produced as they decompose, but the plants that are fertilized absorb more CO2.
--Water consumption is greatly reduced and this almost always has petroleum or electricity invested in its pumping and treatment.
--The need for chemical fertilizers is greatly reduced, and these are responsable for emitting Nitrous Oxide (Greenhouse Gas #3) in their production and use. (And, of course, we have to start forgetting about chemical fertilizers, as they are all non-renewable resources.)
--We sequester carbon into the soil, improving its water-holding capacity.
--Less cement would be needed to build sewers.

It is clear that water scarcity will intensify with Global Climate Disruption and the spread of disease will become more unpredictable (class.coursera.org/warmerworld-001/lecture/41). So this is all the more reason to resolve our own problems productively, on our own, instead of dumping them into the global atmosphere.

The UDDT a key tool for adapting to ever scarcer water.

7. There was limited mention of the challenges involved in deploying this seemingly widely suitable design approach (other than the normal cost factors) - as things are never as easy as they appear, perhaps you can explain where the significant challenges are in simply deploying this approach on large scale in multiple peri-urban locations around the world?

This is my main point of thinking around sanitation.

onsite service models..... why don´t they take off?

This was the reason as well we linked it to the City Partnerships for Urban Sanitation Service Delivery thread. We do see it exactly as that...Urban Sanitation Service Delivery.
And the challenge is to convince the utilities to work with something they do not consider as "their" job. Most see only the sewer and (maybe) the treatment plant as their job. You have to get to the decision makers (first), but than down all the command chain to convince that a service for onsite saniation IS OBLIGATION AND MISSION of an urban service provider.

I am (almost) sure you did not mean that aspect with your question. But it has been our main challenge.

I guess you are asking for the "problem to convince people to use UDDT" as their might be a "culture problem"?
Look this problem is nonexistent (at least in our 800 cases in different climate zones). Once explained in a very clear manor the "bath room concept" - almost everybody who has a latrine (or nothing) goes for that solution.
Obviously you have to overcome a resistance about "this is new to me - can I trust that it works?" But that is for every new solution and my main point against the usual marked driven approaches without adequate promotion the solution. Coca Cola would not be in their position if they did not have marketing. So our market driven approach is different. What we do is, we do clear marketing for UDDT, when we go to the people we don´t say: would you like the black or the yellow lemonade! We say - take UDDT is the best solution for this and that reason. And if they don´t “buy”... no problem, the neighbor will buy. Today the settlements in Lima where we have been active, the people ask for this solution actively.
Problems are in:

  • money - as in our case they had to construct the superstructure on their own
  • what to do with the feces in an urban context

by the second we are back to the service model.
I hope this clarifies a bit of the main challenges.

Yours

For example:

1) Ostara has at least once availed itself of magnesium chloride sourced from a supplier in China (the procurement of which undoubtedly involved the use of fossil-fuel powered ships) [this could be mitigated in some cases by using locally derived bittern;

2) The production of lye (sodium hydroxide) is inherently unsustainable,

3) Ostara's reactor is designed primarily with legacy wastewater systems in mind;

4) Ostara's technology is heavily dependent on large sources of capital and large amounts of energy.

Based on the above, Ostara's "Reactor 2000" strikes me as a classic example of a "green" techno-fix; in other words, something that's being billed as "green" but which will not in the end solve the underlying problem that it purports to be tackling. And as a result this is not something that I would support given that as far as I'm concerned those scant public funds available should instead be going towards systems (like that being pushed by Rich Earth Institute) that will better stand the test of time (and, in particular, the low-water and low-energy future facing us). In marked contrast to Ostara's "solution", source-separation and reuse can be very easily implemented using locally sourced materials and facilitated, if need be, via horse-drawn (or even bicycle-powered) forms of transportation.]]>

I was just wondering what should be the term we should be pushing for when talking about these vehicles? I am asking because I want to do a bit of a clean up operation on Wikipedia.

You called it a "faecal sludge truck" in your card game. Did that come about after long deliberations? I would be inclined to call it a "vacuum tanker".

On Wikipedia I also see pages on:
Vacuum truck: en.wikipedia.org/wiki/Vacuum_truck
Honeysucker: en.wikipedia.org/wiki/Honeysucker_(truck)
Cesspool emptier: en.wikipedia.org/wiki/Cesspool_emptier

I would merge them all into one and then have re-directs from the other terms to the new page (and of course mention the other names on that page).

But I want to make sure that I use the right term that a majority of people from SuSanA would support.
I see that the Compendium calls it a "vacuum truck":
ecompendium.sswm.info/sanitation-technol...ansport?group_code=c

I guess it is not really a vacuum because something is simply pumped from A to B but it is the most commonly used term, right?

Re: Bringing Sanitation Innovations to Market (B-SIM) (WSUP, UK and Ghana, Zambia, Kenya, Bangladesh) - by: tgoodwin http://forum.susana.org/forum/categories/97-enabling-environment/4000-bringing-sanitation-innovations-to-market-b-sim-wsup-uk-and-ghana-zambia-kenya-bangladesh#10682 http://forum.susana.org/forum/categories/97-enabling-environment/4000-bringing-sanitation-innovations-to-market-b-sim-wsup-uk-and-ghana-zambia-kenya-bangladesh#10682
I'll answer on behalf of Andy. Overall, progress has been slower than we expected for several reasons:

First, we're dealing with an experimental technology initiative with a large and diverse set of actors. I’m sure everyone involved in the program feels both how exciting it is to be working with other great pioneers, and also recognizes the difficulty in trying to do so cohesively and effectively. We are in a particularly challenging position to handle this dynamic, as one of the only grantees currently working specifically on 'market activation.'

Second, as a new business unit within WSUP structuring itself to create startup businesses, and do so in the leanest manner possible, this grant (which is essentially to setup 4 new pilot business) required a lot of internal capacity development for us, with regard not only to new people, but also developing our business creation approach to be faster and more effective than in past cases (where we’ve developed new startup businesses in partnership with the various corporate innovation teams at Unilever — including their new business unit and open innovation department).

We're experimenting with an organizational structure to deliver the grant that aims to exit what we call the 'customer development' phase of commercializing these technologies as cheaply and quickly as possible. It's a delicate balance between hiring for fastest milestone delivery and hiring for the long-term sustainability of a fledgling social business.

To balance this, we work through extremely lean country teams and consultants to supplement these teams in places where there are capacity gaps. Orchestrating these teams in 4 countries at once has been our greatest challenge to date.

To hire our core country teams in Ghana, Zambia, Kenya, and Bangladesh we had to first find what we call 'Enterprise Leads’ --who are each responsible for piloting a business and ideally leading it up until the point it's ready for it's first management team. Finding local manager-level candidates with the level of experience, risk appetite, and vision for what we're trying to achieve -- while also not breaking the bank — is difficult.

In a traditional startup environment, you would find co-founders dedicated to the cause and willing to take reduced pay in return for equity. In this environment of intrapraneurship, you can easily find yourself with an unsustainable payroll structure from the outset if you don't hire skillfully. While working with visionary funders like BMGF helps in that we are able to fund staff more like a project than a sustainable business in these early stages, we are constantly thinking about how to best structure startup teams for both efficiency and a smooth path toward ultimately making each business self-sustaining and investable.

Ultimately, we must balance the cost of hiring for skills in difficult talent markets with the desire for strong team continuity through carrying a business to the point of investability. Since the end-game is investable businesses, if we make a model work but do so with an unsustainable team structure, the process of re-structuring the team for cost later on will pose a major threat to carrying forward any one of our models.

To discuss Bangladesh more directly:

The grant in Bangladesh is to “activate the market for on-site sanitation using new toilet designs in Rangpur, Bangladesh” — ideally by utilizing Gates RTTC designs (but this is not ultimately a constraint if we find other designs more suitable and market ready.

We hired the Bangladesh Enterprise Lead about 6 months ago. He is a young diaspora Bangladeshi from Texas, who moved from a Mongolian VC to work with us. He was the only candidate of such a profile that made it into the hiring funnel, and our fortune to find him was only through personal connection.

Other candidates were all Bangladeshi nationals with a "career-NGO” background. Few had ever worked for private companies — almost all had about 15-20 years of project management experience, with no career progression toward bigger projects or more responsibility. While this would be ok for hiring more of a project administrator for a set initiative, it presents huge challenges for a program that includes designing a business model from scratch and building a responsive team that can iterate and evolve the business.

In 6 months, progress has been steady, but slow. First, we originally intended to launch in Rangpur, a small city in the Northwest. However, after initial visits, we determined it wasn't an appropriate foothold market for RTTC. There were a number of active toilet subsidization programs, and residents were too poor to be in the market for upgrading beyond basic sanitation.

Shifting cities required a fresh evaluation of some of Bangladesh's urban areas, and making inroads with the various local city corporations to get an early indication of how supportive the local government actors would be for a program like this. We found the sanitation-as-a-business approach to be very difficult to grasp for many city leaders here, as the poor are not perceived as willing to pay for it, and Bangladesh has a long history of large NGO subsidization programs for latrines. Subsidization, of course, was a huge step in curbing open defecation here over the last 15 years, but it makes the idea of paid sanitation a tricky one.

Toeing the line of social business here is particularly challenging, because if you want to operate as an NGO, it requires a set of approvals and promises of very specific coverage targets agreed with the bureau. However, if you want to operate as a business, city officials may not see any reason to offer important collaborations, such as land concessions or allocation of engineers. Businesses are stereotyped as cutthroat and necessarily corrupt — the practice of paying to get things done is common and accepted.

We ultimately decided to launch our pilot in Chittagong, Bangladesh's second city. The people here benefit from a higher percentage of formal employment than other areas, due to the RMG and shipping industries located here, and basic community improvements in low-income wards have been made by the excellent work of a 10 year UNDP Urban Partnerships for Poverty Reduction program.

The idea of selecting pilot markets is interesting for RTTC, because you’re generally looking for favorable conditions that are still mostly representative of how the market will develop over the long term, rather than looking purely for suitable pilot conditions.

UPPR built roads, water wells, and communal latrines and created a effective community organization structure that we'll be able to build on in marketing sanitation. The prevalence of basic latrine access for most of the population means the low-income market is in prime position to continue moving toward better sanitation as families decide to trade up to more private solutions.

We expect to be able to build on this structure as the UPPR program is retired next year, and believe RTTC toilets could be an appealing offer for this market. In particular, offering toilets with better waste containment and collection service would be invaluable in communities that suffer from heavy monsoon flooding and poor drainage.

Waste treatment is also an attractive path as Chittagong does not feature any functional waste treatment facilities, and 0% of fecal sludge is currently disposed safely. Combined with the fact that many people bathe-in and drink surface water from local ponds, people are very concerned with increasing the overall hygiene and surface water quality of their community.

To date, we have wrapped up a period of intense market research looking across household economics, current sanitation choices, regulatory environment, and reactions to RTTC toilet concepts. We are now conducting design research to build on these market insights and develop technology-independent business concepts. However, several Gates portfolio technologies look attractive as hardware options.

In the coming months, we'll be creating a plan for government capacity development, using a 'collaborative projects' approach we've been developing in Zambia over the last few months. This approach toward identifying areas of alignment between the expected business activities and government stakeholders' priorities will hopefully shift the dynamic between sanitation actors and the government toward a more win-win scenario. From there, our aim is to begin selling new toilets on a free market basis (as the grant describes) in 2015.

Biggest successes so far:
Hiring a solid core team and bringing in the right supplemental expertise to develop and begin testing new approaches to B-SIM.

Main challenges / frustration: Getting up to speed on BMGF project and partnership universe, and making sense of 4 very diverse markets at once.

Links and further readings related to this project: None

To what extent have you achieved the goals already? Market research and consumer insights work either finalized or coming soon in each country. Approach to capacity development defined in Zambia, currently being transferred to other countries. Final pre-pilot business planning and financial modeling underway in Zambia, and coming soon in other countries.

What have been enabling factors? Willingness of people to participate in the research process. In each country, both consumers and stakeholders are eager to be part of developing solutions, and that is critical to designing approaches that work.

When can your technology be brought to scale and under which conditions? N/A

Where do you see its biggest niche or application area? N/A]]>

As Florian said water is not safe or pathogene free, the first chamber just retains suspended and floating solids. Now the water table depth at 1.5 - 2 m seems quite superficial, and in case of heavy rain it may flood specially if soil infiltration rate is low.

Under this conditions a two pit latrine may not be the best solution.
