Dug Well vs Bore Well: Key Differences, Costs & Best Uses Explained
A dug well is a wide, shallow water source excavated by hand or machine down to the first permeable layer, typically 15–30 ft deep, lined with brick or concrete rings. A bore well is a narrow, deep hole drilled 100–600 ft (or more) using rotary rigs to tap confined aquifers, cased with PVC or steel.
People confuse the two because both supply groundwater and neighbors casually say “we’re digging a bore well” even when they’re actually hand-digging a shallow pit. Contractors muddy things further by advertising “bore well digging,” mixing the vocab of manual labour with drilling jargon.
Key Differences
Dug well: 3–6 ft diameter, 15–30 ft depth, yields 500–2,000 L/day, suited for gardens and small homes. Bore well: 4–6 in diameter, 100–600 ft depth, yields 1,000–10,000 L/day, needs submersible pump, ideal for multi-story buildings or irrigation.
Which One Should You Choose?
Pick a dug well if your water table sits within 25 ft and you want low-cost, DIY-friendly supply. Choose a bore well if the table is deeper than 40 ft, demand is high, and you can invest ₹25,000–₹100,000 plus ongoing power costs.
Examples and Daily Life
A village homemaker draws 15 buckets daily from her brick-ring dug well for cooking and cattle. Two streets away, a café owner runs a 2 HP submersible on a 250-ft bore well to keep espresso machines and dishwashers humming all day.
Can a dug well be converted into a bore well?
No. The wide shaft can’t be deep-drilled; you’ll need a new bore hole drilled nearby.
Which option is safer during drought?
Bore wells tap deeper aquifers, so they usually keep flowing when shallow dug wells run dry.
Do both need government permission?
Rules vary by state, but bore wells often require a groundwater clearance; dug wells rarely do.
