I think the use of water is a key factor here. My colleague interviewed some people at evacuation camps who would rather wait to go to the toilet than to defecate without using water. Unfortunately it would be difficult to change such behavior in emergency situations.

Re: A product development framework for emergency excreta disposal (PhD research) - by: yokepean
Thanks for your thought-provoking questions!

When I said "Indonesians must use water", I was referring to anal cleansing. However, pour-flush toilets are the norm in Indonesia so I am unsure whether users would be willing to change their behavior.

There has been some research on the acceptability of dry toilets:

But I am not aware of any real attempts to implement UDDTs in communities here, so we don't really know whether it would be successful. Certainly I think that it is possible, but more research is needed.

With regard to the benefit of UDDTs over open defecation, problems include convincing users that open defecation is unsafe and that it is okay to handle fertilizer that originates from faeces. Community-led total sanitation is implemented by the Health Department but I don't know how successful it really is.

This write-up by the WSP on the factors associated with achieving open defecation free communities in East Java in Indonesia may be useful:

I'm actually from Singapore but have been in Indonesia for two years. I also did a few projects in Indonesia, Sri Lanka and Myanmar prior to starting my PhD.

Re: Handbook for Plumbers on Household connectivity - by: rahulsharma
Thanks a ton for the nice words.

The handbook has been prepared keeping in mind the direct target group (plumbers. As you rightly said, we made sure that the handbook is clear, concise and at the same time detailed for field use. We also tried to keep the language as simple as it could be.

I feel glad to say that we have received positive response from many stakeholders.

Through an iterative process, We (GIZ) have prepared a detailed Manual for Plumbers on Household sewage connectivity and a Training of Trainers Manual on the same subject. The plumbers’ training manual is designed to provide three days refresher training to the plumbers registered with municipalities and it can also be linked with existing plumbing courses in vocational training institutes. GIZ will be supporting its partner states / cities as deemed necessary.

Take care.

Re: A product development framework for emergency excreta disposal (PhD research) - by: canaday
When excrement is mixed in water, the volume of dangerous material keeps getting bigger, whereas with a UDDT the danger is contained and its volume gets progressively smaller.

I invite you to read this interview about the downfalls of flush toilets:
... and this one about the advantages of UDDTs:

Among the advantages of the UDDT is that they can be close to people's homes, thus improving privacy, ease and dignity, compared to Open Defecation. They also eliminate the need for piped water, which can be especially important in an emergency.

Good luck with your study.

100,000 latrines built in Cambodia - single or twin pit? - by: BlakeMcK
I have been asked by Elisabeth:
I thought the 100,000 latrines built ("Easy Latrine") were single pit latrines, but in your last post you said you are now going to twin pit latrines? (You said: "The current approach is to install a second pit, and seal the first one"). I am confused now: Is a significant proportion of the 100,000 latrines in fact twin pit latrines?

The Easy Latrine is designed to work either as a single pit or a twin pit. It is up to the customer, so both options are included in that 100,000 count. The majority of customers initially buy a single pit initially and then add a second pit if/when the first is full, simply to spread the cost out.

Hope that helps

Re: A product development framework for emergency excreta disposal (PhD research) - by: muench
What did you mean by:
most Indonesians must use water

--> did you mean water for anal cleansing or did you mean "they must flush away the faeces", i.e. they "must" always use a pour flush toilet?

If you meant they have to use water for anal cleansing, then this is not a deterrent for UDDTs. We have discussed this here on the forum for example:

If you mean that they "must flush" then you might be interested in checking out this thread about the situation in Cambodia where some people have asked if UDDTs could be an option in order to simplify the faecal sludge mangement system:

Also it could be interesting to read in this thread about UDDTs in Bangladesh which has some similarities to Indonesia - ample water available, Muslim population. I think one selling point for UDDTs there is that they are more suitable for flood-prone areas.

What did you mean by:
I'm not sure that Indonesians would see much benefit in using the UDDT over open defecation

Surely they would see that there is a significant difference as the UDDT would be a safe form of containment of the faeces, and even treatment for reuse?

It's actually great that we hear a bit about the situation in Indonesia from you. We haven't had much on Indonesia on the forum yet!
Which country are you from if it's not Indonesia?

Kind regards,

WERF Decentralized Systems Planning Tool including Spreadsheet for costing options - by: jonpar
Decentralized Systems Performance and Costs Fact Sheets

Small community leaders and planners have a critical need for information and tools to help make good decisions concerning local wastewater management.

The spreadsheet tool provides planning level cost estimations of different decentralized wastewater management scenarios commonly used in small communities. Initial capital costs as well as long-term maintenance and energy costs are included. Users can take advantage of the default unit cost values provided based on national data or use better, local information when available.

The information on this page is not intended to serve as a design manual, but rather to provide small community decision-makers the information necessary to work with engineers, soils professionals, construction managers and financial personnel to get the best wastewater solution for their community.]]>

Re: A product development framework for emergency excreta disposal (PhD research) - by: yokepean

I think it would be difficult because most Indonesians must use water, except perhaps in certain regions where it is very dry. Also, I'm not sure that Indonesians would see much benefit in using the UDDT over open defecation, which would be much more convenient.

However, I should note that I'm not Indonesian so I might not be the most qualified person to answer this question.

forum en français ou en anglais - by: ostoupy2
Merci de nous informer de cette réflexion.
Pour moi aucun problème de poster dans le forum "anglais", soit en français soit en anglais.

Il me semble qu'il y a tout à gagner à avoir un seul fil d'information (ou alors plusieurs fils mais à ce moment là plutôt thématiques que linguistiques).

Bien à vous,

Book on Ecological Sanitation from 2004 - by: mwaniki
Looking for a particular book the other day in our library of sorts I accidentally came across this 2004 edition of 'Ecological Sanitation' which had been commissioned by Sida in the late 90's and published by Stockholm Environment Institute.Its been co-authored by many over the years but the 2004 version has been edited and co-authored by Uno Winblad and Mayling Simpson-Hebert.

See here:;type=2&id=487

The 141 page book (ISBN 91 88714 985)is permissioned to freely revised,abstracted,reproduced in part or whole provided one acknowledges the source of material and is not used for commercial purposes.

Has this book got any relevance to the new 'Compendium of Sanitation' which has recently been released by the forum? The purpose and style of the former looks identical to the description of the latter so the query.

Kind regards / Mwaniki]]>

Re: Training sessions with pit emptiers in Mombasa, Kenya, using the Gulper: resources or educational materials we might use in our trainings? - by: rsklar
Here in Mombasa, emptiers are already using up to 100 gallons of water to remove deeper, drier, and more compacted sludge at the bottom of the latrine. Furthermore, much of the population is muslim washers, so the sludge is quite wet anyway.
We are working in collaboration with a municipal WWTP and our dewatering system is effective at removing solids from their incoming flows that are 0.1 % solid. It is unlikely that watered latrine sludge will be diluted to a level much higher than this so I don’t think water is going to be a particular issue for our operations.

Transporting sludge that has been excessively hydrated will be a major challenge in developing our business model as it will require additional and expensive resources such as more/larger containers, larger trucks, or more trips per empty. The goal of our initial sourcing trial is analyze the cost/benefit ratio of various combinations of sludge removal, hauling, and transportation schemes in delivering the quality and quantity of sludge necessary to drive net gains for our company and the emptiers.]]>

TR: De la section française de Susana Forum - by: Jainil
1. Pensez-vous que cela serait regrettable si la catégorie française « disparaissait » du forum et si les messages en français étaient inclus dans les autres catégories thématiques avec les messages en anglais ?

=> Non, cela ne me semble pas regrettable à ce point, la fusion fait sens, au regard de ce que vous avez mentionné dans votre email.

2. Lisez-vous ou mettez-vous des messages dans la catégorie française ? Si non, pourquoi pas ?

=> Non. Le WG est en anglais, beaucoup de documents scientifiques et donc en anglais 99%...

3. Si nous effectuons ce changement, est ce que vous continuerez à poster des messages en français ou bien plutôt seulement en anglais ?

=> Je ferais les deux…

Hope it helps some !

Re: Training sessions with pit emptiers in Mombasa, Kenya, using the Gulper: resources or educational materials we might use in our trainings? - by: rsklar
Thank you for the warm response. I am in touch with Sherina and her team in Kampala is helping us get a fully assembled gulper 2.0/rammer prototype to Mombasa.

The reasons we chose to go with the gulper 2.0/Rammer over the excravator are the following:

1.Capital cost- The Rammer has significantly lower capital costs ($300 USD for materials and manufacturing). The Excravator run from $1,000 to $3,000, not including the cost of fuel.

2. Accessibility and proximity of prototypes in Kampala and a relatively low shipping cost to our site Mombasa.

We should be receiving the equipment in the coming weeks so I will make sure to update the forum on our experience using the equipment.
