Many thanks Hans. My tool is commoditizing only treated water from wastewater. In the world 90% wastewater is untreated although it is a resource for energy, treated water, phosphorus, polymers...etc...

I often struggled with the concept of a trading market for water, but the idea of trading in rights for waste water or treated waste water could vastly improve the treatment and reuse of various waste streams. But with any market you need buyers and sellers and a market need. Water scarcity is a global issue but in practice it's a local issue which results in a very fragmented market. The big question is how to tie local water needs into a broader trading market?
