Our company is the prominent Borewell Drilling firm from Chennai has completed a large number of Borewells for domestic, industrial and agriculture requirements. We execute Drilling of Borewell by Hand Augur, Calyx, Rotary and DTH Methods.
• Drilling of Borewell by Hand Augur, Calyx, Rotary and DTH
Hand Augur is the most suitable for sandy and highly loose formation with probable occurrence in coastal areas where quality of water can be monitored while drilling and representative soil as well as water sample that can be obtained by constructing effective Borewells and Tube Wells.
Calyx Drills are used in sedimentary and clayey formation occurring mostly in river Alluvium or river banks. To develop a large diameter Tube Wells with gravel /graded pebble packing.
Rotary and DTH:
(Down the Hole Hammer) is perfect for highly compact sedimentary strata consisting of clay, compact clay, limestone, sandstone and common Gondowana sedimentary rocks up to a dept of 1300 ft. DTH drilling is adopted for drilling through weathered medium and massive hard rock formation rapidly up to 500ft.
• Drilling in Hard Rock up to 500' and Sedimentary and soil up to 1300'
Borewell can be drilled inside the open well with a diameter of 4.5 inch and 6.5 inches in rocky strata up to a depth of 300ft.
• Rotary Drilling
Aqua Equipment is a well-drilling company that offers the highest quality well-drilling for homes, businesses and agriculture.
• Rotary Drilling with Mud
In the rotary method of drilling, action is accomplished by Rotating a Drill pipe by means of a power driven Rotary Table or hydraulic powered top head drive, with a bit attached to the bottom of the pipe. The bit cuts and breaks up the material as it penetrates the formation. Drilling fluid for mud is pumped through the Rotating Drill Pipe and through holes in the bit. This fluid swirls in the bottom of the hole is picking up material broken by the bit, then flows upward in the space outside the drill pipe, carrying the cuttings to the ground surface and clearing the hole. The greater the fluid flow the faster the drilling. The drill pipe and bit move downward deepening the hole as the operation proceeds. At the surface, drilling mud flows into a ditch to a settling pit where the cuttings settle to the bottom. From the settling pit the fluid overflows into another pit from which it is picked up through the suction hose of the mud pump and re - circulated through the drill pipe. In the Rotary Drilling method, the casing pipe is not introduced until the drilling operations are completed. The walls of the hole are held in place by the pressure of the mud pump against the sides of the hole.
• Rotary Drilling with Air
Air Drilling is basically the same as Mud Drilling except that the mud pump is replaced by a compressor assembly including cooling system, air receiver and unloading system. The air line is connected to the swivel those at the top of the head drive. The air is forced down through the drilling pipe and out through the holes at the bottom of the Rotary Drill bit. A small stream of water is often introduced into the air system to help cool the drill bit and control the dust. The air serves to cool the drill bit and force cutting out of the hole and is collected at the top. Air is used principally in hard clay or rock formations, once the air pressure is turned off, loose cavy formations would cave-in against the drill pipe. This is not the case when mud is used.
Aqua Equipments has built a solid reputation within the Groundwater industry, and by maintaining a personal involvement in every well project, we have become one of the premier drilling companies in the area. All water wells are designed and engineered to meet specific needs of customers and made from the highest quality raw materials. We provide on-site well consultation to determine optimum location and answer any questions. Our company utilizes drilling contracts to inform you up front of the work we are to provide. We stay abreast of the latest technology and continuing education. Our modern fleet of drilling equipment and service trucks helps us to provide the most reliable service in the industry. These trained employees are courteous and understanding the needs of our customers. This enable by a large compressor which is mounted on a Rotary Drilling Rig. Our rigs are about 30 feet long, 8 feet wide and weight around 20 tons fully loaded.
The Air Rotary method of drilling uses compressed air to power a bit that works in a rotary motion. When down, pressure is applied to the drill stem, hammer, and bit (by large hydraulic pistons) the bit is compressed and begins to hammer many times in a second. This hammer/rotary motion chips or grinds away at the formation to gain footage. Water is also sent down the drill stem under pressure to help cool the bit and to wash the cuttings to the surface.
The actual drilling process begins by boring through loose and broken formation to find solid bedrock. Once solid bedrock is around, casing is installed to prevent contaminants from entering into the well and to insure the structural integrity of the borehole. Casing will not be required for the full well depth, only to solid rock. Bentonite is used at the bottom of the casing as well as the top 10 feet of backfill. This will form a protective barrier against contaminated waters entering into your well from the surface of undesirable aquifers.
A smaller drill bit is inserted inside the casing and the search for water begins. Once the desired amount of yield is obtained, the well is then developed in order to clean the well of drill cuttings and to circulate the water supply. After completion of the drilling and development of the well, then it is sanitized to insure that bacteria were not introduced during the drilling process. We then place a water-tight well cap on the top of the well casing to further protect your water supply.
A well log is completed to provide detailed information about formations encountered and water-bearing zones. Our technicians use this information to seize a pumping system that is specific to the parameters of your well and designed to meet your water usage demands. Once your water system has been designed, we will provide you with cost and also schedule an installation date.
• High Quality Materials
Brass or Plastic materials has no rusting of components. Other well drillers are still using galvanized fittings that may last only 5-10 years, depending on quality of water.
Submersible Pump--Pump is in well, making it more efficient and dependable than the jet pump. We typically install a 12 gpm pump for residential use. Pump size will vary due to application and depth of well.
Pressure tanks size are set according to system and needs. Typical pressure tank size: equal to a 40 gallon capacity/200 Ltrs.
• Repair/replace pumps.
• Repair well plumbing.
• Down-the-Hole Hammer Drilling (DTH Drilling)
I. Method 1: DTH Hammer
The Down-The-Hole Hammer Drill is a pneumatically operated bottom-hole drill that efficiently combines the hitting action, similar to that of cable tool drilling, with the turning action of Rotary Drilling. The pneumatic drill can be used on any standard rotary rig with an integral or auxiliary air compressor of sufficient capacity. It is applied for fast and economical drilling of medium to extremely hard formations. Fast penetration results from the air piston blows transmitted directly to the bit, so practically no energy is wasted in chewing up cuttings. A straight hole is assured by short, rapid blows that minimize the effect of dipping and broken formations. Down-The-Hole Hammer Drilling is by
