specific definition of a "safely managed pit latrines" according JMP ladder for sanitation and guide how to detrmine it in practice

Hello,
I am looking for a specific definition of safely managed pit latrine according to JMP sanitation ladder and practically useful instructions how to assess/determine safely managed pit latrine. Materials which I found through the JMP website are too general.
I am looking for this for our survey in rural Ethiopia where we exepect that (almost) all latrines will be simple pit latrines (dry) with on-site management of fecal waste. Often, they are located in the middle of agri fields.
Thanks,
Josef Novotny

Re: specific definition of a "safely managed pit latrines" according JMP ladder for sanitation and guide how to detrmine it in practice

Hi Josef,
I agree this is a tricky issue in practice. I find the defintion relatively clear, but the monitoring difficult.

For the definition, there are two parts:
1) Improved sanitation facility: "Improved sanitation facilities are those designed to hygienically separate excreta from
human contact, and include: flush/pour flush to piped sewer system, septic tanks or pit latrines; ventilated improved pit latrines, composting toilets or pit latrines with slabs"
2) Safely managed: "Use of improved facilities which are not shared with other households and where excreta are safely disposed in situ or transported and treated off-site"

So a safely managed pit latrine is a toilet that is not shared, has a slab, and where the extreta either is never emptied (a new latrine is built when the pit is full) or the content emptied is transported to a treatment facility.

On the JMP Website ( washdata.org/monitoring/methods/core-questions ) you find a link to recent MICS questionnaire, which in principle should be the answer: mics.unicef.org/files?job=W1siZiIsIjIwMT...sha=fce95f666dcb67c0

There are three questions:
- WS11. What kind of toilet facility do members of your household usually use?
- WS12. Has your (answer from WS11) ever been emptied?
- WS13. The last time it was emptied, where were the contents emptied to?

The first question is supposed to allow to understand if the toilet is "improved" or "unimproved". For pit toilets, the options given are:
- PIT LATRINE WITH SLAB
- PIT LATRINE WITHOUT SLAB / OPEN PIT

I found this one difficult in practice. What can we count as slab? Does it need to be cement or do wooden planks or adobe also count as slab? What if there is a slab but the toilet is very dirty? etc.

The second and third part should allow to understand if it's safely managed (either pit is never emptied, or empied and content safely treated). I have no experience how that works in practice.

I think the JMP is still working on revising the recommended core questions for monitoring, but I'm not sure if they will come up with anything more precice than the MICS questions.

Best, Florian

Re: specific definition of a "safely managed pit latrines" according JMP ladder for sanitation and guide how to detrmine it in practice

Hi Florian,
thanks for your response. As in our previous survey in Ethiopia, I think we would be able to distinguish improved pit latrines based on a solid slab (in the context of our research site slabs are mostly of wood and mud, rarely cemented). However, what may represent a safely managed pit latrine in that context comes quite unclear to me....
Best regards, Josef

Re: specific definition of a "safely managed pit latrines" according JMP ladder for sanitation and guide how to detrmine it in practice

Hi Josef,

Interesting discussion to ask about "safely managed". In your scenario in Ethiopia, are those latrines every emptied? If they are never emptied then this counts by definition as "safely managed". If they are emptied then you'd have to look at how are they emptied and where the fecal sludge is disposed of or treated? Do you already have any information on that?

It will be interesting to see how the definition of "safely managed" will evolve in practice.

Regards,
Elisabeth

Re: specific definition of a "safely managed pit latrines" according JMP ladder for sanitation and guide how to detrmine it in practice

hi

for me 'safely managed' includes:
  1. a slab which prevents people from falling into the pit or having contact to its contents;
  2. a slab which can easily be cleaned preventing people from carrying faeces with their feet to elsewhere, i.e. wooden planks covered with soil I would not consider safe (the distribution of ascari eggs can go this route);
  3. safe emptying of pits, generally they should not be emptied but if it's done it should prevent spillage on workers and into environment (and of course safe transport, treatment and reuse);
  4. latrine pits (and soakaways of septic tanks) should only be built in areas where the percolation of the effluent does not affect the groundwater otherwise people will get into contact with their excreta via the shallow wells or boreholes which provide them with (drinking) water (probably the cause of the recurrent cholera outbreaks in Lusaka/Zambia). Pit latrines which contaminate groundwater are not safely managed.

Re: safely managed sanitation system in rural area

What sort of sanitation systems (technology options) can be recommended for rural areas to achieve safely managed sanitation systems as defined by JMP definition? Does pour flush toilet with twin pits (with bottom unlined) serve as a safely managed sanitation system in rural area?

Re: safely managed sanitation system in rural area

Hi All Members
Toilet with unlined bottom or any leach pit toilet ( single or twin pit) should not be considered as safely managed sanitation system particularly for the areas having high ground water table and / flood affected as there is severe chance of ground water pollution from such toilets. In most of the rural areas, ground water is the only source of drinking water, such toilets may result in severe health hazards.
Such toilets with properly slab cover and water seal may be suitable for the areas having very low ground water table. In some states in India , where water table is very high and there is annual floods, leach pit toilets are not a suitable option.

Re: safely managed sanitation system in rural area

thanks for all replies.

To Elisabeth, based on our previous experience we expect that latrines in our Ethiopian research site (Sidama Zone, SNNPR, Ethiopia) are simple pit latrines which are not emptied.

Regarding the Hajo´s comment nm 2, I expect that many or most slabs in the research area are made of "wooden planks covered with soil". Your point is clear but I assume that this type of slab (if solid) still doesnt prevent a pit latrine to be considered as "safely managed" latrine according to JMP classification. As for the comment nm 4, this is also clear but to assess whether the location of a latrine is "safe" or not may obviously be tricky. We will probably use the 15 metres threshold from a well or hand-pump as suggested in one of the JMP advice sheets, although I think that the safe threshold may be quite context-dependent.

Regarding Pawn´s comments, water-seals are not common in our research site where almost all pit latrines are supposed to be dry latrines.

I have one more question related to location. Although the location of latrines with respect to water sources are commonly discussed, I have not found much on other potential risks related to location. For example, in our case, we assume that many pit latrines in our research site are located in very direct proximity of vegetable paths or agriculture fields. Does it pose any specific risks and should this be considered when assessing whether a latrine is safely managed or not?

Re: safely managed sanitation system in rural area

Hi everybody
One can maintain 15 meters distance from toilet to own well or hand-pump. But quite difficult to maintain such threshold from neighbours well or hand-pumps. In India to maintain 15 meters distance in most of the rural areas is impossible due to very high population density.

With regards to agricultural fields the rule of thumb could be "the closer the toilet the better" - this is with regards to the reuse potential that you have here. We have many impressive photos showing how well banana plants do in proximity to a current or formerly used toilet pit!

Re: safely managed sanitation system in rural area

It is important to define the type of crop in proximity to human waste. Bananas are okay but salad greens are not! Food crops that are cooked might be okay too. Reuse of either solid or liquid contents from pit latrines should be viewed with extreme caution. The biggest problem with pit disposal is concentration. There is no getting around that, whereas properly treated wastewater could be dispersed via irrigation and be environmentally sustainable.

I would also add that a single pit cannot really be emptied safely in practical terms, but a twin pit can. I think it is illegal in India now to handle sludge from a pit, but decomposed humus from a twin pit is okay.

Re: safely managed sanitation system in rural area

Thanks, my worries concerned vegetables in the very proximity of single pít dry latrines. But have not seen any study on this
