These show some of the processes going on in the soil, and the "live" nature of the soil that you referred to previously.

I agree with your statements. You are obviously very good & precise at expressing the proper soil-related terms.....I think it would be great if you could be the moderator of a thread on a topic of your choice that would benefit the forum on the issues we have been discussing online and offline.

thanks for your direction on this stuff that us non-soil experts just call "dirt" sometimes !

I am going to upload some pics to clarify some of the issues brought up and correct my previous mis-us of "profile".

I've developed some prototypes of a pit emptying device, see



This is not a universal solution, of course, but should work well in some places, and is certainly better then the poor men climbing down into the pit.

I've also developed a low water clog-proof toilet, see



I've used this for a while and it works well, though it needs some changes.

I'm also working on an above-ground latrine made of a barrel for high water tables, which can be emptied using something like the mechanism shown in



This one is still in the early stages of development, so I can't claim too much yet.

I have one question related to the "The Prohibition of Employment as Manual Scavengers (and their rehabilitation) Act, 2013".

On some of your flash cards it states that this law "prohibits manual cleaning and
emptying of pit toilets and septic tanks"

While at other cards the Twin-pit toilet is promoted as a good technology for the future (which I agree with, providing water source protection measures are in place). How does the manual scavengers act regard the manual emptying of twin pit latrine pits in your interpretation?

Thanks, I was aware of the DEWATS booklet by Sasse, et al. I find a bit unfortunate that they presented the formulas used in the spreadsheets as EXCEL code, rather than as the formulas they used to base the Excel code on.

Probably, a lot of the formulas that were used for this booklet are still valid. Though for colder climates some parameters (such as up flow speed)may have to be adjusted.

So we might say that the soils in a field were predominantly clay. This is shorthand, because soils vary considerably spatially.

But, (again!) unfortunately, soil classification is also the wrong term and refers to something else. And soils can be organic, if they are composed of a large amount of organic material. The point is that you don't use this triangle, because it is only relevant for mineral soils - other soils exist.

Again, I appreciate this sounds very technical and boring, but this is the way it is. Soil Science is more complicated than many think!

On the fertility point, I would say that David's sample would be hard to apply in amounts which would not give a negative effect on the fields he has to spread them on. Too much would likely have a negative effect.

But the main problem (other than the pH) is that those particular soils are already pretty high in nitrogen, so adding more is not going to be doing anything anyway. Crop growth is not going to be limited by nitrogen.

If there was really a problem with acid soils, then one would be better off using the lime directly on the soil rather than in the latrine (of course, this is not ideal given the need for sanitation, so there is a conflict).]]>

"The results indicate that the alkalinity was the limiting factor, which
controlled the application rate. The waste would have to be applied at 1/10” to prevent harm to existing soils. This application rate could continue for 20 years without harm to the soils."

At the very thin application of 1/10", it was obvious that the plants were not going to receive much nutrients. And in this case, it wouldn't harm the soil, because I limited restricted the application rate to 1/10". Another words, as an agricultural amendment, it was not beneficial]]>

Thanks for clarifying....I was limiting my statement to the extent of my knowledge of the triangle's use....this is what we used in Geotechnical Civil Engineering class for civil purposes..building roads, etc.

Glad to see the soil scientists use it also

My point in presenting the triangle was to show the three-fold aspect of soil, per this triangle, plus loam. I always found the graphic way of presenting this definition of soil, was useful in understanding what "soil is"]]>

Note also that this is not a soil profile, which is a different thing.

en.wikipedia.org/wiki/Soil_texture

I can define soil profile if anyone is interested.

But to reinforce, these are not only geotechnical terms, but are very much terms used by soil scientists to assess agricultural land. Geotechnics is the study of engineering properties of soil.]]>

These soil profiles are usually used to classify soils for their structural properties, not agricultural value, but it gives you another perspectives on what civil engineers view what "soil" consist of]]>

Re: Results based financing for sanitation – do the costs outweigh the benefits?

I look forward to joining this webinar next Wednesday even though (or because!) I know very little about results based financing for sanitation so far.

I welcome you all to use this thread to already now pose any questions you may have about this topic to the speakers and also to use it after the webinar to continue the discussion. Perhaps you would also like to share your own successful or unsuccessful projects with results based financing here?

The first question that I - as a novice - had, was "is results-based financing the same as output-based aid (OBA)?". The easy answer is: no.

In the Castalia report that Pippa mentioned above (www.susana.org/en/resources/library/details/2177), there is a nice overview on page vii with the definitions:

+++++

Results-Based Financing (RBF) is an aid mechanism where payments are made to service
providers upon verification of the delivery of desired outputs, or the performance of
desired behaviors.

RBF needed to be distinguished from three closely related mechanisms:
- Payment for Results (PfR): PfR provides loan disbursements to governments upon
verification of desired outputs. These disbursements are loans to governments, rather
than grants to service providers.

- Public-Private Partnership (PPP): Governments contract with private firms to provide
services, such as through concession or performance-based contracts for operations
and maintenance, and may pay for services provided under the contract.

- Viability Gap Funding (VGF): Donors provide upfront grant contributions to cover gaps
between what customers will pay and what providers need to be paid, instead of
providing output-based subsidies.

There are various types of Results-Based Financing. The three main types of RBF used in
WASH are shown below.

Type of RBF:

Output-Based Aid (OBA) - In OBA projects, service delivery is contracted out to a third
party—public or private—which receives a subsidy to complement or replace the required user contribution.

Conditional Cash Transfers (CCTs) - CCT projects provide cash payments to poor households
that meet certain behavioral requirements. Note: We had a discussion about CCT started by Madeleine here on the forum not long ago: forum.susana.org/forum/categories/164-fi...and-sanitation#11185

Voucher Programs - In voucher projects, a consumer receives a redeemable voucher from a Government or donor agency which can be exchanged for a specified good or service.

++++++

Another thing that I thought could be useful to point out is that some of these topics have Wikipedia pages already, for example:
Conditional Cash Transfers: en.wikipedia.org/wiki/Conditional_cash_transfer
Output-Based Aid (OBA): en.wikipedia.org/wiki/Output-based_aid
Payment by Results: en.wikipedia.org/wiki/Payment_by_Results

I can't judge whether these pages are good or not, as it's not my area of expertise and as I haven't read them carefully yet (I still plan to do so). Perhaps as part of this webinar process, folks could look at these pages and make improvements or state on the talk pages what improvements are necessary. Perhaps we could also insert here and there relevant sanitation project examples (with references to projects, and hyperlinks to sanitation) so that people reading up about these finance mechanisms are also pointed towards sanitation as a possible application area.

What do you all think about these suggestions?
