Dear Cecilia,
by reading your matter, many thoughts run through my head, but one was a little scary - you talk about " the final product- potable water ". Normaly, the natural resource is (should be) already "potable water" ! So i´m not quite shure whether you talk about a business-model to earn money by purifing (waste)water or a supply-chain in the mood of a multi-barrier-system to keep resources unpolluted.

Dear Thomas, thanks for answering. You correctly write "should be". Many cases show us that both rainwater and groundwater in particular, need to be treated because they are polluted. In the case of groundwater, it could be saline through intrusion of seawater, or the soil is very permeable so that is polluted by chemicals from the ground (the case of pacific islands). Rainwater also, it is not safe itself, but also the ways of storage rainwater could be obsolete and pollutant. Nowadays, I think, we can not take for granted that water from natural resources is potable.
