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

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