Inventor of the service chain graphic

Dear All
The service chain graphic attached herewith is ubiquitous; it features in most presentations and some publications related to sanitation and FSM in particular. However, I have seen it cited differently in these presentations.



Was wondering who really invented it and where was it first used?

Thanks
Paresh

Re: Inventor of the service chain graphic

Hi Paresh
This is a good question. I believe the first major publication describing the various linked components of the sanitation value/service chain was the so-called "Compendium" produced by EAWAG in 2008. A second revised edition came out in 2014.
To be found here: www.eawag.ch/en/department/sandec/publications/compendium/

Indeed the diagram was popularized by the Gates Foundation Re-invent the Toilet Challenge
www.gatesfoundation.org/What-We-Do/Globa...the-Toilet-Challenge

and the FSM conferences www.fsm4.susana.org/

Re: Inventor of the service chain graphic

Literature defining Sanitation value chain has been totally changed. Now, every literature and the online platform even all international organizations advocate for the same definition of sanitation: Capture--- containment---- empty. & transport ---- treatment and disposal

However, the definition of sanitation previously covered a broad framework, now, it is being narrowly defined, presented and mental model being created around FSM.

Sanitation now not being defined as : Capture --- Conveyance (sewer network) ---- treatment and disposal

Why is this happening so?
