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,

F H Mughal

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

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.

Dear Elisabeth,

You say:

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.

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

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:

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?

Elisabeth

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.
