You Californians should blame your politicians. Saving stupid fish and shit. You have the ocean, create desalinization plants! Your not getting any more water from Colorado.
Cost of a 50 MGD desalination plant is ~$0.5 billion (the carlsbad one is $1 billion but it is the first large scale one in california).
Using LADWP, which supplies water to the City of LA as an example: LADWP bought ~220,000 AF of water from MWD in 2012. That's 220,000 * 325,000 gal/AF = 71,500,000,000 gallons per year or 195 MGD. To meet LADWP imported water demands, you'd need at least $2B worth of desal plants. Given that it is nearly impossible to build anything on the coast, I'd estimate the cost would be at least double.
So for every major city in California dependent on the state water project, expect to spend $2 billion each.
https://en.wikipedia.org/wiki/California_High-Speed_RailThe California High-Speed Rail Authority has estimated the project's year-of-expenditure cost at $68.4 billion (2011 estimate).[3] In July 2014 The World Bank reported that the per kilometer cost of California's high-speed rail system was $56 million, as compared with $1721 million per km in China and $2539 million per km in Europe.[4]
In Orange County CA where I live they have a Aquifier beneath the County that they draw water from including using imported supplies. Over a decade ago the Orange County Water District built a Ground Replenishment System. Previously treated wastewater was just dumped to the Ocean. Instead it undergoes further treatement to make the water drinkabled. They inject this water back into the aquifier. Purifying wastewater is about 1/3 the cost of current desalination processes. Right now about 20% of the water that refills the Aquifier comes from the treated wastewater program. They are in the process of exanding the system. Apparently LA wanted to do the same thing when Orange County was doing it but the resident's got all rilled up and called it toilet-to-tap and the program was shutdown. I think LA is taking another look at the process again.
We have to be smarter about how we use water in Southern CA. Right now I am working with my Gardener to come up with a design plan for re-doing my front yard and tear out all the grass and plants etc and put in climate correct vegetation. Trying to come up with a plan that my HOA will approve.

And this is a huge problem too. If the HOA insists on having green lawns there should be reclaimed water available to water it. And of course the problem isn't restricted to HOAs as there are many cities that have antiquated laws on the books concerning landscaping.Trying to come up with a plan that my HOA will approve.

At least LA is smart about that; DWP will pay $3/sqft if you replace your lawn with water-friendly landscaping.
Well we're the ones being yelled at to reduce usage.....
Thats cool about the aquafier, I agree about wise use of water. Through the ongoing problem I think we will see a lot of innovation come of it. I love dual flush toilets.

My water district offers $2/Sqft to tear out grass. Once I started this project and started really looking around I realized the small number of yards that really use climate correct vegetation. At least in my discussion with my HOA there is nothing prohibiting me from tearing up my grass and replacing it. I think some HOA's still require grass. The State Legislature was looking at a bill to block HOA's from requiring grass. The sponsor was stating that apparently some HOA's didn't get the memo that we are in a drought. I know my HOA used to require grass.
Small article in the local paper about drought tolerant landscaping.

You guys are concentrating on LA when you guys should really be concentrating on the central valley.
Ours does not but one of my neighbors put in fake grass and it looks pretty good. No watering and no constant mowing/trimming. Kind of appealing actually.
In some of the cities around here, it's not uncommon for $100/month water bills. What's the population that the LADWP would serve? Estimating 4million people, 2 billion dollars is $500 per person. Spread out over 10 years (120 months), that's a little over $4 per month per person. What's California waiting for??
edit: or if it's 10 million in Los Angeles County, then it works out to $200 per person, or $6.67 per month for a family of four, over 10 years.

I'd hope that it would be a public project as water is a requirement for life. But, you're probably correct to a degree if it were a private project. Sadly, a public project would still be rife with people trying to make some bucks out of it.Um, you forgot to add the PROFIT margin. It would be more like $75.00 per month for 20 years, just for a little PROFIT.
