Comprehensive Guide to Water Well Drilling: From Site Selection to Completion
2025-07-17
Site Selection
Drilling Equipment Selection
Drilling Process
Rotary Drilling:Uses high-speed rotating bits to cut through soil, suitable for soft formations with high efficiency.
Casing and Screen Installation
After drilling, casing and screen installation are critical to ensure well longevity:
Screen:Installed inside the casing, the screen acts as a filter to block sediment and ensure water clarity.
Well Development and Equipment Configuration
Cost Factor Analysis
Well drilling costs vary based on multiple factors; advance planning helps avoid overspending:
Geological Conditions:Hard rock formations increase drilling time and equipment wear, potentially doubling costs compared to soft soil.
Additional Expenses:Permits, surveys, and pump systems typically account for 10%-20% of the total budget.
It is advisable to reserve 10%-15% of the budget for unexpected geological issues or equipment failures.
Water well drilling is an engineering that "communicates with the subsurface." Each step from site selection to completion requires scientific decision-making and meticulous operation. For those without experience, professional teams are recommended—after all, a high-quality well can provide clean water for decades, making it a worthwhile investment.
