Assuming no delays, not a drop of water will be produced before 2022. It takes astonishing time to build infrastructure.
Nice groundwater recharge project. What is the hold up on this one? Is funding the issue? The most common delay is environmental permitting - years for an EIR and related permits for anything major, and then a few lawsuits on top of that usually.
Let's be clear here, it's another great project, but this is not water independence. The project you linked to is trying to stop importing water for the purpose of recharging the groundwater. A lot of that goes to stop saltwater intrusion into the aquifer. They're importing 11,500 acre-feet, which is a drop in the bucket for that population.
I don't want to rain on your parade, these are all great projects, but let's get the numbers straight.
This graphic says it all - look at the south coast. The unimpaired water availability is much lower than the use. If they captured all the rainfall, the urban use would still have to drop in about half from what it is now. Those are two huge goals that are worth struggling for, but not likely to ever happen.
