Studies show that California has enough water-but where does it go? February 26, 2010

Dr. Peter Gleick, president of the Pacific Institute wrote an article about the amount of water wasted by California. As you probably know, California now has a mandate to reduce water consumption by at least 20% by the year 2020. While this seems like quite a reach, it is actually very easily attainable.
The way California could meet—and possibly surpass the goal—is by reducing wasted water. For example, over 50% of toilets today are non-efficient versions, wasting up to 2 gallons per flush. Also, more than three quarters of Californian crops are watered by inefficient irrigation systems. By retrofitting these fixtures, water use would be significantly use. The excess water saved by these methods could very easily be diverted and used by other Californian crops, to help boost the economy and provide jobs for the unemployed.
On a related note, building a dam (The Temperance Flat Dam) could cost over $3 billion. The resulting increase in water supply is estimated to be only approximately 200,000 acre-feet of water. The clincher is that it is estimated to cost only $2 billion to retrofit toilets and irrigation systems, with a savings of over 400,000 acre feet. The choice is yours, California. Choose wisely.
