What is considered a shallow well?

Shallow wells are typically defined as wells less than 50-75 feet deep, though some definitions extend to 100 feet. They tap into unconfined aquifers near the surface rather than deep bedrock water sources. In San Diego County, most residential wells are 200-500 feet deep—not shallow by industry standards.

Are shallow wells cheaper than deep wells?

Yes, when conditions allow shallow drilling. A 60-foot shallow well might cost $8,000-$15,000 vs. $25,000-$45,000 for a typical 300-500 foot deep well. However, most San Diego County properties don't have sufficient groundwater at shallow depths, making deep wells necessary.

Can I have a shallow well drilled in San Diego County?

It depends on your property's location and geology. Valley areas with high water tables may support shallow wells, but most inland hillside and granite-dominant areas require deep drilling. A professional site assessment determines if shallow drilling is feasible for your property.

What are the disadvantages of shallow wells?

Shallow wells are more vulnerable to contamination, more affected by seasonal droughts, may have lower flow rates, and can go dry during extended dry periods. They also have limited lifespans compared to properly drilled deep wells into bedrock aquifers.
