I had a look at the TAF and TIP tools; unfortunately, it looks like this tool is better used to assess how a pilot should be planned, assess how that pilot goes, and then how further implementation should be approached. We are wanting to look at an even earlier stage than pilot testing; we're looking for a test plan that would be an example for assessing the technical aspects of a prototype technology prior to any introduction in the field. If you think of any other resources that focus on this earlier stage of testing, I would be interested to learn about them.

Thank you again for the introduction to the TAF and TIP tools, they are informative and could be useful for future projects.

All the best,
Jenelle]]>

I'm looking for an example test plan that has been used to assess new sanitation technology(ies). Ideally the test plan would be for assessing sanitation technology at the prototype phase, but any example would be appreciated.

Thanks!

Re: Criteria to assess the safety, sustainability and functionality of the feacal sludge management practice at household level - by: muench http://forum.susana.org/component/kunena/53-faecal-sludge-management/19130-criteria-to-assess-the-safety-sustainability-and-functionality-of-the-feacal-sludge-management-practice-at-household-level-cameroon#19592 http://forum.susana.org/component/kunena/53-faecal-sludge-management/19130-criteria-to-assess-the-safety-sustainability-and-functionality-of-the-feacal-sludge-management-practice-at-household-level-cameroon#19592 )

I like how you use the Forum to get inputs to your PhD research. In order to help you better, can you please clarify your question?
What kind of criteria do you mean? If you mean sustainability criteria, these have been discussed in various places on the forum (use the search field at the top right to find previous threads containing "sustainability criteria").
If it's something else then please clarify?

Advice on SFDs (shit flow diagrams) and informal sanitation chain in informal settlements (e.g. Nairobi, Kenya and elsewhere) - by: leftyrights http://forum.susana.org/component/kunena/53-faecal-sludge-management/19536-advice-on-sfds-shit-flow-diagrams-and-informal-sanitation-chain-in-informal-settlements-eg-nairobi-kenya-and-elsewhere#19536 http://forum.susana.org/component/kunena/53-faecal-sludge-management/19536-advice-on-sfds-shit-flow-diagrams-and-informal-sanitation-chain-in-informal-settlements-eg-nairobi-kenya-and-elsewhere#19536
I'm exploring where and how fecal waste flows in Nairobi's informal settlements, comparing 2 slums to capture some variations that may be missed in past SFDs (e.g., areas differing in their use of pit latrines, access to sewers, public toilets, or Sanergy's Fresh Life Toilets, and how disposal patterns vary during rainy season, at night etc.). I'm also interested in maintenance of toilets, with some gendered consideration of female/male residents who strive to keep these facilities clean. My aim is to reveal some of the spatial variations and informal practices that are often obscured SFDs, and I hope to map & explore these flows with local stakeholders like latrine-emptiers, community leaders, public toilet caretakers, etc. I plan to work with Kenya's slum-dweller federation, Muungano wa Wanavijiji, to build on their existing maps of toilets in these areas. In turn, I hope to generate some fine-grained information that may support future advocacy and behavior-change interventions.

If possible, can you recommend any publications, contacts, or projects that may be relevant? Here are some that I'm already aware of:
-SaniPath's recent work, including SuSanA videos from the 2016 SFD meeting in Stockholm
-the latest FSM work from WSP, which include SFDs with more detailed consideration of informal settlements' flows in Lima, Dhaka, etc.
-UBSUP in Kenya
-WSUP's project with emptiers in Kibera
-studies of 'modernized mixtures' in East African sanitation (by Letema, van Vliet etc.)
-work in Uganda on gender and sanitation maintenance (e.g. Kwiringira, J., et al. (2014). Gender variations in access, choice to use and cleaning of shared latrines; experiences from Kampala Slums, Uganda. BMC Public Health, 14(1), 1.).

If you know of other publications or contacts I could draw upon, I'd be very grateful. I have limited resources so I won't be able to conduct household surveys, unfortunately. But I'd appreciate any tips about how to sharpen the study, complement existing work, or make it more useful to practitioners or policymakers.

Thank you and all the best!

Realistically speaking on-site sanitation will stay the defacto standard in most places for the foreseeable future, therefore the need for FSM. But my impression is also that many engineers only prefer sewerage systems because that's what they learned in university, and often they also don't consider the necessary construction of a large sewerage treatment plant to be "part of the deal"...

The question which arises is what is the problem if septage remains in tank for long duration besides the fact that it starts hardening thereby reducing effective size of the tank.

Besides that it is a myth that many tanks are oversized (people don't sufficiently consider the necessary hydraulic buffer and that tanks are already technically full when the sludge & scum occupies some 2/3 of the available volume), you need to stop thinking of individual tanks and see it as a city wide problem. Then there is always quite a lot of tanks that would benefit from emptying. And of course if you want to avoid sludge hardening, emptying more often is also a good soluntion.

Regarding the frequency see comment about city wide scale above. Grey-water is basically not a major issue pollution wise as for most households it is a low-strength, low volume, few health issues problem.
For septic-tank effluents: The problem starts in the tank, the need to treat the sludge is actually a secondary result of the necessary emptying. Assuming a reasonably well constructed multi-chamber septic-tank additional secondary effluent treatment is only necessary in densely settled areas (with shallow ground water abstraction) or for environmental reasons to reduce the nitrogen/phosphorus pollution load.
However as soon as the tank is not emptied early enough (=FSM) this turns around and then (and only then) the effluents become a real pollution problem. And in addition any secondary effluent treatment system will be quickly overloaded and damaged.]]>

The book can be downloaded in the SuSanA library: www.susana.org/en/resources/library/details/2100

If your actual question is why it *should* be prioritized (but isn't), than that is easy: any sanitation coverage figure will tell you that globally much more people have on-site sanitation than are conected to a sewer system.

P.s. the purpose of such a home work is doing literature research, not asking other people to do the work for you

P.P.s.: if you are referring to effluent from a septic tank and not a sewer system, than again it isn't really. But I agree that this is probably a bit of an overlooked topic... but a full septic tank without good effluent treatment is much worse than an regularly empied one without.]]>
