Dug Well vs. Bore Well — What's the Difference?
By Tayyaba Rehman — Published on January 27, 2024
A Dug Well is a shallow, manually excavated water well, while a Bore Well is a deep, narrow well created using drilling machinery.

Key Differences
Dug Wells are traditional water wells created by manually digging up the earth until groundwater is reached. They are typically shallow and have a wider diameter. Bore Wells, conversely, are constructed using drilling machinery to create a narrow and deep well, often reaching deeper groundwater layers.
The construction of a Dug Well is less complex and requires basic tools, but it can be labor-intensive. The depth is limited to how far a person can safely dig, usually not exceeding 30 feet. Bore Wells require specialized drilling equipment and can reach depths of several hundred feet, accessing deeper aquifers.
In terms of water quality, Dug Wells are more susceptible to contamination due to their shallowness and open nature. Bore Wells, being deeper and often sealed, are less prone to surface contamination, offering better protection against pollutants.
Maintenance of Dug Wells is more demanding, as they can easily be affected by surface runoff and require regular cleaning. Bore Wells, with their deep and enclosed structure, require less frequent maintenance but can be more challenging and expensive to repair due to their depth and construction.
The water yield of a Dug Well is generally lower and can be affected by seasonal changes in the water table. Bore Wells, tapping into deeper aquifers, often have a more reliable and consistent water yield, though they are more susceptible to depletion and geological changes.

Compare with Definitions
Dug Well
Prone to surface contamination.
Their dug well required frequent testing to ensure water safety.
Bore Well
Lower maintenance but complex repairs.
Repairing the bore well's pump required specialized equipment.
Dug Well
A manually excavated shallow water well.
They dug a well in their backyard to access groundwater for irrigation.
Bore Well
A deep well drilled using machinery.
They drilled a bore well to reach the deep aquifer on their property.
Dug Well
Affected by seasonal water table fluctuations.
The water level in their dug well dropped during the dry season.
Bore Well

The bore well was over 200 feet deep but only a few inches wide.
Dug Well
Typically wider in diameter.
The dug well was wide enough for a person to climb down for cleaning.
Bore Well
Offers consistent water yield.
Despite seasonal changes, the bore well consistently supplied water.
Dug Well
Requires regular maintenance.
Cleaning the dug well was an annual task to prevent algae growth.
Bore Well
Less prone to contamination.
Their bore well provided cleaner water due to its depth and casing.
Common Curiosities
How deep can a dug well be?
Usually up to 30 feet deep.
Can a dug well be used for drinking water?
Yes, if the water is tested and treated for safety.
How long does it take to drill a bore well?
It varies, but it can take a few days to several weeks.
How do you maintain a bore well?
Regular checks and maintenance of the pump and electrical systems are needed.
Can bore wells dry up?
Yes, especially if the aquifer is depleted.
Can dug wells get contaminated easily?
Yes, due to their shallow depth and open nature.
Are there legal regulations for drilling bore wells?
Yes, many regions require permits and compliance with environmental guidelines.
Is a dug well cheaper to construct?
Generally, yes, due to its simplicity.
What is the lifespan of a bore well?
It can last for decades if properly maintained.
Can you manually clean a bore well?
No, due to its depth and narrow diameter, specialized equipment is needed.
Can bore wells improve water access in arid areas?
Yes, they can provide water in areas where surface water is scarce.
Are bore wells environmentally friendly?
They can be, if managed sustainably and responsibly.
Do dug wells require a pump?
Not always, but pumps can be used for easier water extraction.
How do you know where to dig a well?
It often involves surveying and understanding the local water table and geology.
Do dug wells affect the landscape?
They can, especially if not properly managed or secured.
