(Water) Well Digging

Found a good "Well Digging" link? Let Us Know!

Water Wells Tutorial. Folks, I couldn’t believe my eyes when I saw this site. It is absolutely amazing! This tutorial shows new drillers how to construct safe water wells. There are also technical details and instructions for experienced drillers. You can even print out and disseminate the tutorial with their permission!

Wells Hand Dug Wells Construction: Hand Dug and Hand Drilled. Most of the materials, tools, and methods covered in this manual are applicable throughout the world in a variety of local situations. The techniques are designed to be useful in the rural areas of most developing countries. Step-by-step plans outline construction materials and techniques to be used where skills may be limited. Although all potential situations cannot be covered, this manual provides enough background to allow workers to assess unusual situations, and determine what available techniques might be useful.

Ground water: Wells There's a good chance that the average Joe who had to dig a well in ancient Egypt probably did the work with his hands, a shovel, and a bucket. He would have kept digging until he reached the water table and water filled the bottom of the hole. Some wells are still dug by hand today, but more modern methods are available. It's still a dirty job, though!

EPA Private Drinking Water Wells > Basic Information > Dug Wells Dug wells are holes in the ground dug by shovel or backhoe. Historically, a dug well was excavated below the groundwater table until incoming water exceeded the digger’s bailing rate. The well was then lined (cased) with stones, brick, tile, or other material to prevent collapse...

UNDERSTANDING WATER WELLS By William Ashe. This paper tells how to dig a well that provides safe drinking water for human consumption. Wells for animals and irrigation can be constructed to a much lower standard.

Shallow Wells Field Manual - Dig the Hole for the Well A pictorial manual with little text but fairly self-explanatory graphics.

Don't dig down In a twist to the usual practice of digging deep bore wells in search of water, Mohammad decided to try scouring for water horizontally. His success at this unusual method has earned him the nickname 'adda-bore', and many satisfied clients. Shree Padre reports.

HOW TO DIG AND TAKE CARE OF WELLS [PDF] When centralized water supply is absent, provision with water, first with drinking water, is very important. Dug and drilled (artesian) wells are used for extraction of drinking water from water-bearing layers...

Well Digging: Modified Chicago Method. For making hand dug wells safely, cheaply and better. The original Chicago Method was developed in order that deep foundations could safely be excavated by hand to depths in excess of 40 meters in clay soils having no significant water-bearing inclusions. This modified method is suitable for water wells in lateritic and clayey soils where the water is expected to accumulate by seepage from the lower part of the excavation. Great article!

Sinking a Drive Point Well. Interesting. Only good down to 100', though.

Sludger Technique (Nepal) Sludging is used extensively in many parts of Asia to bore holes of 25mm to 150mm in diameter to depths of up to 60 meters. The water table must lie within 6.5m of the surface and the strata must be soft alluvial deposits such as those found in the river flood plains of Bangladesh, Nepal and northern India.

Well-Jetting Technique (Nigeria) Well-jetting is a simple technique for inserting small diameter wellscreens into shallow sandy water bearing aquifers. Unlike conventional boreholes which require heavy drilling equipment, well-jetting is carried out by hand using just one or two portable engine pumps to produce a powerful jet of water.

Hand Dug Village Wells (Uganda) Water from the ground has many advantages for rural people in developing countries. It is usually free from the bacterial contamination associated with surface water in regions where sanitation facilities are not common. Hand dug wells are another source of water being developed in the Kabarole district of Uganda...

FM 5-484 / NAVFAC P-1065/AFMAN 32-1072 Military Well Drilling Manual This manual is a guide for engineer personnel responsible for planning, designing, and drilling wells. This manual focuses on techniques and procedures for installing wells and includes expedient methods for digging shallow water wells, such as hand-dug wells.

Forager Drill Cable percussion (cable tool) drilling is the oldest, simplest, and most reliable technology available of water well drilling. It will drill any material and is completely self contained - requires no mud, mud pits, pumps, chemicals, compressors or hammers, yet will drill through rock.

Hand Powered Percussion Drill (Liberia) The percussion drill is one of the oldest known tools for making holes in the ground to get water. Records show that it was used by the Chinese in 1100 BC and it still is a very popular method of drilling today. The early percussion drills used strips of bamboo tied together with a heavy metal weight on the tip.
