To minimize water quality and quantity impacts, dug wells should be at least 3 m (10 ft) deep and sited away from surface water sources. Surface water can carry contaminants from the land surface into your well and the aquifer. Check with your local government about setbacks for construction of wells near streams, lakes and wetlands.

3.2 Dug Wells. Dug wells (Figure 7 and Figure 8) have large diameters (typically 600 to 1500 mm) and are usually relatively shallow (3 to 10 m deep), extending only a few meters below the water table. They were historically the most common type of domestic well because they could be constructed by hand without the need for heavy equipment.
well drilling. What Is A Dug Well? Wells that are less than 50-feet deep and are constructed above the bedrock are called dug wells. They are also referred to as shallow wells, wash wells or gravel wells. Digging an effective well depends on the soil type – they are often surrounded by sandy gravel. Shallow wells can be used for drinking ...
Dug and bored wells are large diameter boreholes that extend from the surface to some shallow depth. They are usually three or more feet wide and. less than 100 feet deep. They store water that seeps in from the water table and near surface materials. They are typically installed where no traditional aquifer is available, leaving them as the ...

The world wide popularity of hand dug wells is accounted for by the ease of construction without specialized equipment, the simplicity of water raising equipment (a bucket on a rope has worked for thousands of years), and the ability of the Dug well to hold a large volume of water in storage for times of peak demand.

Dug wells are usually constructed during dry weather when the water level is at its lowest, both for safety (less likely wet soils cause well collapse) and to determine the necessary depth of the Dug well to obtain adequate water supply. Details about how to dig and construct a hand dug well such as the Oaxaca hand dug well shown at left, begin at ...
The hazards of hand dug wells include poor sanitation (ground water and surface runoff easily enter the drinking water supply), and cave-ins during construction or injuries to tools dropped into the well during construction. We are particularly concerned about the safety hazards to children when a dug well does not have a child proof wall and/or co...
"Well safety" in the literature collapses two rather independent areas of concern 1. Safety of the well water - is the well water potable or safe to drink? discussed at DUG WELL POTABILITY TEST where we include additional resources on well water safety 2. Well construction safety - Safety for workers during well construction as well as safety again...

Water Well Basics. There are approximately 100,000 domestic water wells in New Brunswick. The two main types of wells found are drilled wells and the less common dug well. Historically, dug wells were dug by hand but today, they are usually dug with the use of a back hoe. Because they are shallow, dug wells are more vulnerable to contamination ...

To minimize water quality and quantity impacts, dug wells should be at least 10 feet (3 m) deep and sited away from surface water sources. Surface water can carry contami-nants from the land surface into your well and the aquifer. Provincial regulations require a well to be sited away from possible sources of contamination; at least 20 feet (6 ...
