I should have been more clear in saying that I am NOT trying to offset the costs with any sort of recovered value, but am rather looking into ways in which the costs are feasible, fair, and acceptable to all members of the system.

It wasn't correct of me to say "very few ways" because actually, in my particular context, there are "no ways". More correct would have been to say that I have not found any ways to make the system cost neutral, and very few ways to optimize the payments between the customers and providers, such that we can maximize use and minimize operating costs.

I will definitely keep you posted once my results are ready to share!

with regard to the increase in prices for "P", a look onto charts for the last decades and price development does not show an abnormal increase in these prices; rather, speculation spin-offs might play a bit, as with other raw materials.

www.indexmundi.com/de/rohstoffpreise/?wa...sphat&monate=240

unveils a bit of reality as opposed to hopes one might have for alternative sources for phosphate. The chart linked-in above displays prices for Moroccan raw material. A geologist's point of view: Morocco is leading exporter for phosphate, but not the only one. Significant resources can be found, e.g., in Spain and some other (north) African countries.

We should remain realistic with expectations, please. Collecting, transporting, processing and using urine in agriculture will, for the foreseeable future, remain dependent on low wages and low income in remote areas in -for the processing purpose- climatically appropriate regions.

You raised some very pertinent questions in you post on 20 May 2014. From the answer by David I draw my own conclusion that there is no full cost-recovery with the Sanergy model in Kenya yet. It is on the one hand a bit disappointing but on the other hand not surprising, i.e. why should they be the only one worldwide who have found a way to make sanitation provision for the urban poor be able to support itself, solely based on fees, and without any government subsidies (or, in their case, external donor support or some other form of long-term investment)? I think it is simply not possible and need not necessarily be our aim either, as we are talking here about a public good - sanitation, public health (just like education).

You wrote:
I've been doing some modelling for my own research about how a urine collection and transport system can be sustainable and regardless of the scenarios (that I run) I find very few ways in which the income exceeds the costs (especially considering increasing labour and fuel prices).


What are actually these "very few ways"? I asume things like the scenario that fertiliser (phosphorus) prices go up a lot compared to now? That's actually the only one I can think of right now.

(Related thread to this is the VUNA project thread:
forum.susana.org/forum/categories/98-res...12&start=12#7350)

Oh and there was also a post by Kris on Smart Sanitation Subsidies which nobody has picked up on yet:

I've been doing some modelling for my own research about how a urine collection and transport system can be sustainable and regardless of the scenarios (that I run) I find very few ways in which the income exceeds the costs (especially considering increasing labour and fuel prices). (A brief summary is available on the VUNA website: www.vuna.ch)

I would be so grateful to find out more about the breakdown of your (Sanergy) costs (labour, transport, manufacturing) and how you cover those, in terms of franchise fees, nutrient sales, etc. If you're not operating at a cost-recovering point yet, but see that as the goal, how long do you think it will take to get there (measured in terms of toilets or nutrient volume, etc.)?

Many thanks!

Thanks for the thoughtful piece on our new Fresh Life Toilet design. We appreciate the spotlight as well as the analysis of our work.

One point that we would like to clarify in response to the comment, "One disadvantage is that due to the production process (heat moulding if I remember correctly), the squatting plate now has to consist of two parts (because the urine section is so deep), which means they are joined, and that joint could be a weak spot in terms of urine stone deposits and clearning issues (my personal guess)."

While there are two parts to the squatting plate, the joint which connects the two parts is a shingle joint, which easily allows for liquid to flow over both parts.

However, as we have only in the last 6 weeks put the new design into circulation, it is still too early to tell about the exact wear and tear that the design will take.

David Auerbach]]>

Fresh Life Toilet in Kenyan slums - improved urine-diverting squatting plate (Sanergy in Nairobi, Kenya) - by: muench http://forum.susana.org/forum/categories/106-user-interface/8635-fresh-life-toilet-in-kenyan-slums-improved-urine-diverting-squatting-plate-sanergy-in-nairobi-kenya#8635 http://forum.susana.org/forum/categories/106-user-interface/8635-fresh-life-toilet-in-kenyan-slums-improved-urine-diverting-squatting-plate-sanergy-in-nairobi-kenya#8635
Many of you have heard of Sanergy, the impressive social business venture serving an ever-growing number of people in low-income areas in Nairobi, Kenya (also present here on the forum: forum.susana.org/forum/categories/52-mob...ry-loo-user-and-kiva).

Whilst they are not yet a grantee of the Bill & Melinda Gates Foundation, they are an important partner for the BMGF because quite a few of the other grantees are using Sanergy as a full-size testing ground (or "real life lab") for their R&D work. One example is The Climate Foundation with their pyrolysis reactor, see here:
forum.susana.org/forum/categories/98-res...-usa-and-kenya#8628.

For that reason, Sanergy was also invited to exhibit at the Reinvent the Toilet Fair in Delhi, India, in March 2014.

Here you can find some photos that I took from their exhibit:
www.flickr.com/photos/gtzecosan/sets/72157644699243384/

I had the pleasure of interviewing one of Sanergy's co-founders, David Auerbach. The focus of our conversation was their newly designed urine-diverting squatting plate - which simply looks awesome, see for yourself here in the photos and two videos:

Fresh Life urine-diverting squat plate by Sustainable sanitation, on Flickr

Urine-diverting and splash-reducing squat plate by Sustainable sanitation, on Flickr

See the interview with David Auerbach here (focussing on the new squat plate that they exhibited):



The second part of the interview, which describes the Sanergy approach and business model, as well as their collaborations with other grantees is available here:



The improved squatting plate has the following benefits:
  • Less splashing due to a "fin" which is also used in urinals, and due to a deeper urinal section.
  • Urine hole and faeces hole are closer together on a horizontal level, so that less horizontal shifting of the user is needed when they are doing both, one after the other (i.e. urination and defecation).

One disadvantage is that due to the production process (heat moulding if I remember correctly), the squatting plate now has to consist of two parts (because the urine section is so deep), which means they are joined, and that joint could be a weak spot in terms of urine stone deposits and clearning issues (my personal guess).

You can barely see that joint on this photo, almost at the very base of the deep urinal section:

Questions and comments are welcome, I am sure that David or one of his team members will be happy to answer them here on the forum.

Kind regards,
Elisabeth

Some further information about Sanergy's current work:

Some more information from a recent blog post of Sanergy:

A Fresh New Look for the Fresh Life Toilet
saner.gy/archives/4592

An excerpt of their recent blog post:

Through a partnership with MCAD Technologies and Dassault Systèmes SolidWorks Corporation, a computer-aided design software company, Mike was able to bring the new Fresh Life Toilet to life through 3D modeling, structural simulation of parts, as well as renderings and manufacturing drawings to communicate designs with vendors and field experts.

During initial user testing it was very clear that women were subjected to splash-back when they used the toilet. The new urine-diverting squat plate has a unique form with a deep urine bowl and a splash-eliminating ‘fin’. The squat plate is made from a hard and glossy plastic that is easy to clean and lasts longer than previous squat plate designs.

Key information:



Fresh Life Toilet

In African slums, Fresh Life makes hygienic sanitation
accessible and affordable for everyone, forever. We
franchise a dense sanitation network of clean toilets,
collect the waste, and convert it into valuable byproducts.
As of January 2014, 12,000 residents in
Nairobi’s slums are using Fresh Life Toilets every day
with a projected 200,000 in 5 years. Sanergy’s franchising
creates financial opportunity while solving a critical
social and environmental challenge.

Toilet Design

The Fresh Life Toilet is based on a continuous customer
feedback loop and related user research suggests that
a clean, comfortable and friendly sanitation experience
dramatically increases uptake. The Fresh Life Toilet
delivers an enjoyable experience by leveraging features
such as an easily cleaned tile floor and an ergonomic
splash reducing squat plate for women, men, and
children. A durable concrete modular construction,
coupled with powerful community-driven branding –
in partnership with Wash United - makes Fresh Life
preferred sanitation option for all slum residents.

Thanks for your post, good to see you back on the forum! These two videos are well worth watching, I think you have some very nifty, low-cost design ideas there for light-weight mobile toilets for emergency settings (trialled in Haiti). I really admire your enthousiasm which comes out clearly in the videos - and boy, was it a hot day! We were sweltering in that heat in March in Delhi (no shade!).

For those without access to Youtube, I provide here some photos from the exhibit.

Cheers,

My interview about project story (questions asked by Elisabeth):



In this video you can see me giving a guided tour of our exhibit (it was a hot day with little shade!!):



Short description copied from Technical Guides (susana.org/lang-en/library?view=ccbktype...p;type=2&id=2001), page 5:

Aerosan: Low-Cost Sanitation
for Emergencies


Aerosan has developed a four-toilet array as well as a
separate single-unit cubicle. Key to the design is the
use of enhanced passive ventilation for both control of
odors and also drying of excreta. The material can be
subsequently composted. The low-cost construction
approach using re-purposed vinyl billboard fabric allows
for a large plenum (a space provided for air circulation
and venting), which, driven by a Venturi is able to move
more air through the system than would normally be
available in a typical 4” (100 mm) vent pipe. The design
puts the outlet of the plenum 15’ (4.3 m) above the
ground, so odors are released at a higher elevation than
typical vented toilet cubicles.

Several units have been deployed for field testing in Haiti
and are operating at a high level.

The unit shown at the Delhi toilet fair is fully functional
and will be an improved design from the one shown
at the first toilet fair in Seattle in 2012. Design
improvements have focused on reducing the weight, cost,
and improving the wall and plenum structures. Also,
the whole design will be available in kit form for use in
emergencies.

How it works

The primary technical feature of this toilet is the design
of a passive ventilation system which draws more air
than is necessary for simple odor control. In this way,
a degree of drying takes place which reduces volume
accumulation of excreta and thus increases the number
of users that can use the system per maintenance
period. Ventilation is both wind and solar-driven, but all
passive.

Those are all questions that we will be able to answer with more precision at the end of the year or by july 2015.

We are analyzing everything: toilet, transport, inputs, fixing, replacements, etc. But we are starting the process of reducing costs through different approaches: materials, suppliers, etc. We are also approaching the local MFI's and realizing alternatives.

The same for the value chain, we are just studying the different and more cost-effective ways to do it. We can now speculate on panoramas, but we will know at the end of the year or by July 2015. Several approaches are under research; we are also developing audio-visual toolkits for installation and for O&M.

We promise you more information in the future!]]>

Is the 700 US$ how your are calculating arriving at 5 cents per use (e.g. 5 people, 4 uses/day) over the 3 years?
Are you expecting any O&M costs -> e.g. for the mechanics of the “flush” system?

In the pre-fabricated units: will the “flushing” system be already installed and pre-assembled or is this something users would need to montage them self after delivering. Or are you thinking of working with a intermediate actor responsible for the “do-it-your-self” (e.g. certified artisans offering toilet installation)?
