Low-cost sanitation for emergencies - Aerosan in New Delhi - by: muench http://forum.susana.org/forum/categories/106-user-interface/3425-low-cost-sanitation-for-emergencies-tested-in-haiti-aerosan-usa-and-haiti?limit=12&start=12#8312 http://forum.susana.org/forum/categories/106-user-interface/3425-low-cost-sanitation-for-emergencies-tested-in-haiti-aerosan-usa-and-haiti?limit=12&start=12#8312
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.

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)?

Kind regards
Dorothee]]>

However this seems to be an example of the small size of the company holding back the overall idea. I hope the exposure through these kind of events will interest someone with more financial reserves to speed up development and bring it to scale.

Find attached the interview that SuSanA did to us during the Reinvent The Toilet Fair in India.

It was amazingly motivating being there. We get great connections from visitors, but also potential partnership and alliances with other exhibitors -plus the quick learnings and feedback that you can harvest just during the fair-. I will not say more, since I am sure that after playing the videos comments and questions will come!





Thanks SuSanA team for this!

Prototype's final cost and other associated costs (as housing and restrooms accesories -urinals, sink, greywater pipes-) are still under research and development.

To supply the units or let the users doing it by theirselves is a good question. Critical Practices is now working on developing Injection-molded units because it is the most cost-effective way to manufactur the toilets, but the alternative of working in drawings and manuals for a "do it by yourself" is something that I know its under analysis.

The expectation would be that the unit's cost, Ex-Factory, would be between $100 and $200 depending on the prototype (Chuck can explain further about this). Then users can decide on superstructure and accesories, as well as installation. However, we are also developing easier and cost-effective approaches to the superstructure and accesories. One goal -thinkign in the Latin American context-, is that we could have a complete unit, including the Earth Auger toilet, accesories, superstructure, reainwater collection system and greaywater+urine irrigation system for less than $700; that could mean that users do a downpayment of aprox $80 and then monthly payments of $15 to $20 for 3 years. Of course a simpler alternative could be less than $500, including superstructure and basic accesories. We are approaching local MFI's in Ecuador and will have more information during the year.
