Climate Change Impact on Water Well- Latrine Distance

It is known that the distance between a water source (well) and location of latrine is influenced by the soil gradient contours and soil texture, among others.

Climate change is becoming a increasingly important topic, with each passing day. I would like to know, whether the climate change will influence the distance between water source and the location of latrine.

Re: Climate Change Impact on Water Well- Latrine Distance

Indeed, climate change is a depressing thing that's happening right now with very scary consequences on many levels. :(

About your question:

I would like to know, whether the climate change will influence the distance between water source and the location of latrine.

The safe distance is influenced by many parameters around hydrogeology. We had a good discussion about the checklist of Working Group 11 here:
forum.susana.org/193-groundwater-polluti...f-sanitation-systems

Wolf, L., Nick, A., Cronin, A. (2015). How to keep your groundwater drinkable: Safer siting of sanitation systems - Working Group 11 Publication. Sustainable Sanitation Alliance
www.susana.org/en/resources/library/details/2155

So I would say that if climate change leads to more rainfall in a certain area and more flooding, then you would probably need to increase the distance of the well to the pit latrine. If climate change leads to less rainfall and droughts in certain areas then you can perhaps reduce the distance.

What would you (and others) say?

Dear Elisabeth,

You say:

If the distance is worked out under drought conditions, what happens if there is heavy rainfall?

Re: Climate Change Impact on Water Well- Latrine Distance

On the subject of climate change, I think, it will be helpful if Susana develops guidance manuals on impacts of climate change on sanitation and water supply facilities, and how to deal with those impacts (adaptation and building resiliency).

Susana may contact some German universities, or London-based WEDC, Loughborough University, etc, for developing the guidance documents.

Re: Climate Change Impact on Water Well- Latrine Distance

Dear FH Mughal,

At pS-Eau we've initiated some work on WASH and climate change since COP21. We produced a document on WASH services and climate change, based on the reflections from a working group. This document aimed to 1/ characterize climate hazards affecting water ressources and services 2/ identify the risks on water and sanitation services 3/ draw some courses of action for adaptation.

The work is still ongoing: we presented this document at several events including COP22 and we plan to gather our working group again before COP23, in order to answer the comments and feedbacks we received, and further reflect on the solution chapter.

Attached is the working document (in English and French) :

and you can also find it on our website : pS-Eau web page : WASH and climate change . If you have some comments on the document, you're welcome to drop me an email at genevaux[at]pseau.org.

Best regards
Colette

Re: Climate Change Impact on Water Well- Latrine Distance

Dear Ms. Colette,

That is a interesting document. As this is a working document, I suggest, you send it to the Asian Development Bank, the World Bank, and UNEP, for comments. Over a period of few months, I think this will become a major guidance document.

Yes, I have some comments, which I will sent you at your personal email, as you say.

Regards,

Re: Climate Change Impact on Water Well- Latrine Distance

Dear Mughal,
Regarding your call for SuSanA to develop guidance manuals on impacts of climate change on sanitation and water supply facilities; I just want to inform you that SuSanA WG3 (Renewable energies and climate change) is leading a paper on linkages between sanitation and climate change. This aims at providing some general guidance on how sanitation can help address climate change. The initial drafting of this paper has been supported by the SuSanA Phase III project and by a group of students from the Cranfield University. Later this year I expect that the draft paper will be shared on the forum to receive comments and feedback from Forum members.

I can also recommend having a look at the factsheet from WG3 'Links between sanitation, climate change and renewable energies' that provides some useful orientation.

All the best,
Kim

Dear Kim,

That is nice and interesting. Could I know, when the final study would be ready; and how we can access it?

Re: Climate Change Impact on Water Well- Latrine Distance

Dear Mughal,
According to the preliminary time plan, the draft discussion paper on linkages between sanitation and climate change will be shared with a broader audience at the end of August, in connection with Stockholm World Water Week 2017. Signing up as a member of WG3 is one way to be kept in the information loop!

Best regards,
Kim

Re: Climate Change Impact on Water Well- Latrine Distance

Dear all,
Sorry for the silence in reporting back about the progress on this factsheet/discussion paper on linkages between sanitation and climate change, that I mentioned a couple of months ago. We have deviated somewhat from the original timeline. We are still working on a initial version, that we aim to have ready to share on the forum for feedback, linked to the COP in Bonn in November. Please see the presentation from the 24th SuSanA meeting in Stockholm, 26 Aug 2017, which provide a background to the paper and an overview of proposed content. See:
www.susana.org/files/Susana-meeting-August-26_EC.pdf
Of course we are happy to receive any comments on this first idea of structure of the paper. But we especially look forward to your feedback and potential contributions when we have the first draft of the paper in the beginning of November.

All the best,
Kim
