Dear Kirsikka,
first of all thanks for the fast putting online of the presentations.
I started to go through some of the presentations, as I´m mainly interested in scale up I started to look in the section 2 TECHNOLOGICAL OPTIONS AND URBAN APPLICATIONS.
My eyes were drawn to "
How (not) to design and construct UDDTs - a comprehensive guide to functionality"
. The first part of the presentation is very interesting. I just don´t agree with the conclusion of the authors
"Need for a comprehensive manual on UDDTs which
highlights critical issues and provides dos and don’ts to avoid the errors."
Some two to three years ago that might have been right. In Latin America we developed a manual (the photo is in the material as well) which covers exactly that point of practical approach for different materials and situations for bench style UDDT. So one question to the authors would be (I know Lukas is reading the Forum), in you opinion what is lacking in the manual?

My question is not rhetoric, we tried to cover exactly the critics the authors had, so it would be interesting to have their view on that.
As I said from my point of view the main point is not the availability of manuals any more. I think the two other points stated in the paper as well are crucial:
o Engineers unaware of / underestimating important details and their implications
o Insufficient supervision during construction
It is simply very expensive to do supervision for each toilet. We came to the conclusion the only way is to train constructers and when they are good you keep on working with them, if they don´t deliver quality just change. For larger scale a quality list could be a solution.
There are lots of examples which are constructed with costs which are not replicable in scale, therefore "not valid".
But I´m close to be drifting to another topic,
my main aim in this post was to motivate people to write about the presentations they looked at, in order to see if we can by this have a quicker overview about interesting papers.
Yours
Christoph
