Semitropic, established in 1958, covers an area of 220,000 acres serving approximately 140,000 acres having an irrigation demand of approximately 450,000 acre-feet per year Semitropic is one of eight water storage districts in California and is the largest in Kern County.. . It began as an irrigation district for the purpose of securing State Water Project supplies to reduce groundwater overdraft
Semitropic has developed and currently operates the worlds largest aquifer storage and most unique agricultural water delivery system on the planet. The District delivers water to nearly 300 customers for irrigation of approximately 140,000 acres for agricultural uses. Semitropic also supplies energy to its water users and provides groundwater banking and storage services for districts and companies from San Francisco to San Diego. Developed in the early 90s. Semitropic began its groundwater storage program in response to several challenges from the 1980s, including:
. • groundwater overdraft
• rising energy costs
• rising water costs
• water shortages
• poor agricultural economy
The development of the Semitropic Water Storage Bank was based on three primary objectives:
• Increase water supply reliability.
• Decrease the cost of water for irrigation.
• Correct overdraft in the groundwater basin.
Since its initial operation in the mid-1990s, Semitropic has received water for storage from banking participants approximately 1.5 million acre-feet in a groundwater storage bank with a permitted capacity of 1.65 million acre-feet and has recovered and returned approximately 800,000 acre-feet in drought years. The banking program contributes to meeting the drought-year needs of more than 20 million Californians at 15 to 20 gallons per person per day.
