... however not conserving water as a means of making a statement about the contradictory messages we get from various government entities in reality doesn't hurt them in the least, let alone cause them to stop building. ...
That's not entirely true. A lot of the S50 approvals and objections are tied to the water rights and how much we currently use versus how much is still available under Folsom's rights. Our water savings have directly resulted in them being able to avoid finding a new water source. While they would no doubt find another way to screw us, not saving water would make it more difficult for them. While it would hurt in the short term (using too much water this year may mean trouble in a few months), in the long run, the current population using 100% of the allocated water vs the current population + S50 using that same amount of water results in the same amount of water being consumed, but with the consequence that we would REALLY be screwed when we have another drought after S50 is built out and Folsom's allocation has a mandated reduction (which I think our legal allocation has already been forced to be less the last couple of years, it just happens to still be more than we use). Then all of us would be forced to save a lot more than we are now or the taps run dry even more dramatically than they could now.
