California has not built a single new reservoir in over 40 years despite their population doubling in size. Only an environmental extremist would think that is acceptable.
Think about this: If a husband and wife had a 30 gallon hot water tank in their home and then decided to have 2 or 3 kids, do you think they would get a bigger hot water tank?
The primary problem in California is not; 'Lack of water' it is lack of planning for the periods when there is a lack of precipitation.
On a side note I was consulting with one of the contractors involved with trying to get the Santa Barbara RO plant back up and running (after 24 years in mothballs). One of the issues was all the computer data was stored on 7" floppy discs!
I'm afraid that's not the case...
Diamond Valley Lake was started in 1995
Of course, this lake is fed by the Colorado River aquaduct, and virtually no water has been coming from that source for a few years now.
Don't have two or three kids here, but our home has two hot water tanks, one is a 100 gal tank and the other is a 40 gal tank. Reason for the 100 gal tank is a large Jacuzzi tub in the master bath.
