How much does irrigation well drilling cost?

Irrigation well drilling typically costs $20,000-$60,000+ in San Diego County, depending on depth, flow requirements, and pump size. Agricultural wells often require larger diameter casings (8-12 inches) and higher horsepower pumps (3-10+ HP) than residential wells. Cost factors include required GPM flow rate, drilling depth, geology, and distance from power source.

What flow rate do I need for irrigation?

Flow rate requirements depend on acreage and crop type. General guidelines: 10-15 GPM per irrigated acre for row crops, 8-10 GPM per acre for orchards/vineyards, 15-20 GPM per acre for high-demand vegetables. A 10-acre vineyard typically needs 80-100 GPM. Golf courses require 200-500+ GPM. We calculate precise requirements based on your specific irrigation plan.

Is irrigation well water cheaper than municipal water?

Yes, significantly cheaper for high-volume users. After initial drilling investment ($20,000-$60,000), irrigation well water costs only electricity to pump—typically $0.03-$0.08 per 1,000 gallons vs. $5-$15 per 1,000 gallons for municipal water in Southern California. For a farm using 1 million gallons annually, well water saves $5,000-$15,000 per year. The well pays for itself in 2-5 years for most agricultural operations.

Do I need special permits for an irrigation well?

Yes, irrigation wells require the same San Diego County well construction permit as domestic wells. Agricultural wells may have additional requirements depending on location and aquifer protection zones. Some areas restrict new agricultural wells due to groundwater management concerns. Water rights and usage reporting may be required. Your licensed contractor handles permit applications and ensures compliance with county and state regulations.

Can I use an irrigation well for livestock water?

Yes, irrigation wells can provide livestock water. Livestock water requirements: cattle 10-20 gallons/day, horses 8-12 gallons/day, sheep/goats 1-2 gallons/day. A 50-head cattle operation needs approximately 750-1,000 gallons daily. Most irrigation wells easily meet livestock needs plus crop irrigation. Water quality testing is important—high nitrates, bacteria, or minerals can affect livestock health.
