Q: How deep and in what soil types is the Village Drill effective?
The Village Drill is designed to drill up to 90 meters (270 ft.). The Rig includes 50 meters of drill string. The average depth is 45 meters. It will drill through almost all water bearing soil types, including sand, silts, medium/hard grade rock, coral and clay.
Q: How do I learn to use the Village Drill?
A: Learning how to operate the Village Drill only takes a couple of hours. General drilling principles like where to drill or how to install a pump is best done with a local experienced artisan. Operational training is available upon request. Various training materials and videos are included with every drill.
Q: How long will it take to drill a well with the Village Drill?
A: In many cases, just one day. In ideal conditions, the Village Drill may average 40 meters (120 feet) or more per day. In harder formations depths of five meters (16 feet) a day may be common bus.
Q: Where is the Village Drill Manufactured?
A: The Village Drill is currently manufactured in Mombasa, Kenya and in Utah, USA.
Q: How much does the Village Drill cost?
A: The costs with all tools and commercial drilling components to start your drilling activities is $18,000 USD, plus shipping and various taxes (based on destination).
A: What is the drilling method?
A :The “cable tool” method that has been around for thousands of years, uses a rope and tripod to raise a heavy bit and then drops the bit to pound the earth. The typical Auguring system uses a drill style bit that you manually turn and you then lift the cuttings out of the hole. The Village Drill is a rotary, “wet drill” process. This technology allows us to bore into the ground very quickly and remove the cuttings as we are drilling. Cable tooling and auguring have long been replaced in the drilling industry by the more efficient and effective wet rotary method.
Q: Where will it work?
A: The Cable tool and Auguring methods can only drill effectively in a fraction of the environments that the Village Drill can drill, where the Village Drill can drill faster and more efficiently in every condition that the cable system and Auguring systems can work.
Q: How is the efficiency?
A: You have heard the saying “go pound sand”. The cable tool and Auger system is very inefficient in really soft soils like sand, in muck like sticky mud and in hard surfaces like rock or hard clay. The Village Drill thrives in all these environments.
Q: How do you get the cuttings out of the hole?
A: The Village Drill method of removing the cuttings from the borehole is a huge advantage. The Village Drill removes the cuttings as it drill’s, as part of the drilling process. The auger you have to lift every bite section completely out of the ground and cable you have to pound and cut the ground and then change tools to remove the rubble and then go back to pounding. This is a very slow and arduous process by comparison.
Q: Will all drilling reach the water aquifers?
A: Ironically, one of the Achilles heels of cable and auger drilling is water. Typical cable and auguring techniques cannot pass through “ground water” levels to reach aquifer levels. The problem with ground water is it is still commonly shallow and is still contaminated from runoff and two, groundwater is prone to drying up in the dry seasons. The Village Drill has the capability to pass right through groundwater levels and can easily reach aquifer levels which are typically pure from biological contaminates and much less susceptible to dry season variations.
Q: What is the cost to drill a well?
A: To actually “drill” a well, the cost between a Cable Tool system an Auguring system and the Village drill is virtually the same. Though the Village Drill has the advantage of being able to always drill a standard 6-8” borehole that will accommodate nearly all power and hand pumps on the market. With a smaller borehole that is often necessary with a cable tool or an auguring system you become very limited on what pumps you can use.
Q: Is the diameter of the borehole wide enough to install a submersible solar powered pump?
A: The Village Drill uses commercial bits and the largest one included creates a 7" borehole which will take just about any style pump. The most common hand pumps are India Mark II and the Afridev (they usually cost between $600-$900 USD). Most submersible pumps, whether solar or electric are 3" to 4" in diameter and as long as you use the proper size casing available, you won't have any problems with either (submersible pumps usually go for between $200-$400 USD).
At the end of the day we suggest that groups use whatever is common for their area so replacement parts are easy to come by. And again, the actual hole size the Village Drill drills is the same as the big rigs, so whatever pumps the big trucks are installing will typically be great for the Village Drill boreholes as well.
