One lesson that everyone by now should have learned or at least starting to think very seriously about, "close the cycle" All I ever see is "taking" never ever "giving". Your water source is like your bank, first relies on deposits. You can't keep "taking", no over drawn accounts, without some means of a returning, or making up the deficit. (Re-Charge) Done properly in a co-operative you can raise operational revenues for water in and water out. The quality of service will deteriorate,  you will run out of cash, the well will run dry. So my friend before you can get some solutions to your request,, what actions have been considered to return some of that valuable water used back in to the aquifer, river, stream, sea, from which you withdraw. ? This will dictate much of any strategy at local or city level. Just an observation for now.
