Yeah, don't forget the leaks that are losing 25% of the water, lack of a grey water capture network (we have this in the US ffs!), as well as the fact desalinization plants make the water toxic at the outflow à la Red Sea style.

It's an epic mismanagement and I think there is a water war brewing. Although BCN has so far denied it, everyone knows that the water of the Ebro is on the table and BCN can be quite ruthless as far as pillagign the south.
