Why DIY Shallow Well Drilling Isn't Recommended for Irrigation

Drilling a shallow well for a lawn sprinkler system may seem like a cost-saving project, but it involves significant technical challenges and risks. This article explains why professional installation is strongly advised.

The Scenario

A homeowner in North Florida with sandy soil and a water table at 16–20 feet wants to drill a well to about 40 feet for irrigation. They consider using a hose-based drilling method but are unsure about the process, screen installation, pump hookups, and other details.

Why Professional Installation Is Necessary

• Complex variables: Soil composition, water quality, aquifer characteristics, and local regulations all affect well design and performance.
• Equipment and expertise: Proper drilling requires specialized rigs, casing, screens, and development techniques to ensure adequate yield and prevent contamination.
• Pump sizing and installation: Matching the pump to the well's yield and the irrigation system's demand is critical for efficiency and longevity.
• Legal and safety concerns: Many jurisdictions require licensed well drillers. Improper construction can lead to aquifer contamination or structural failure.

Recommended Approach

Contact a licensed well drilling or pump company for a site evaluation. They can assess the feasibility, obtain permits, drill and develop the well, and install the appropriate pump and controls. Some companies may allow the homeowner to assist with certain tasks to reduce costs, but the critical steps should be performed by professionals.

Investing in a properly constructed well ensures reliable water supply for irrigation and protects groundwater resources.
