As the world's largest, most productive, and potentially most controversial water system, [2] [page needed] it manages over 40 million acre-feet (49 km 3) of water per year. [3] Use of available water averages 50% environmental, 40% agricultural and 10% urban, though this varies considerably by region and between wet and dry years. [4]
The Metropolitan Water District of Southern California (the largest entitlement holder) pays $298 per acre-foot ($241 per 1,000 m 3). This basically means that cities are subsidizing the cost of farm water, even though the cities also provided primary funding for the construction of the SWP. [69]
The construction and application of a membrane bioreactors in the demonstration facility cost nearly $17 million dollars and the total cost of building the full-scale program will be $3.4 billion, resulting in an annual operation cost of $129 million, and water cost of $1,830 per acre-foot. [19]
By 2050, California is expected to lose between 4.6 and 9 million acre-feet of its annual water supply. In other words, by 2050 at the latest, Californians would lose access to a volume of water ...
One acre foot of water is enough to supply two families of four for a year. Of that, about 4.5 million acre feet are held in the State Water Project, a network of 30 reservoirs and storage ...
The CVP stores about 13 million acre-feet (16 km 3) of water in 20 reservoirs in the foothills of the Sierra Nevada, the Klamath Mountains and the California Coast Ranges, and passes about 7.4 million acre-feet (9.1 km 3) of water annually through its canals.
Opinion by Marek Warszawski: “One year’s worth of recharge won’t significantly raise the water table. But an extra 600,000 acre feet definitely doesn’t hurt.” California plans to divert ...
The cost of water from the plant will be $100 to $200 more per acre-foot than recycled water (approximately 0.045 cents per gallon), $1,000 to $1,100 more than reservoir water (approx. 0.32 cents per gallon), but $100 to $200 less than importing water from outside the county. [42] As of April 2015, San Diego County imported 90% of its water. [13]
