Groundwater Exploration & Exploitation Geophysics and Geology, in the past few years, has reached at the zenith for the scientific development and protection of the world's precious groundwater supply. Geophysical investigations of the buried strata can be made either from the land surface or in a drilled hole in formation.
Selection of Site Using Electrical Resistivity Survey We select the site for both Borewell and Dugwell purely based on the principles of Geophysical Investigation using Electrical Resistivity Meter. Exploration for Groundwater involves the investigation of areas for the proper location of wells. Electrical Resistivity investigation offers highly applicable and useful aid in discovering Groundwater resource and quality Groundwater. The depth of water table can also be determined from resistivity soundings. Resistivity Survey is used mainly to determine the subsoil lithology and to assess the potential of Groundwater in the area being investigated. The Investigation will also provide us with probable depth at which water is available to drill accordingly. We also do the drilling based on the water divinity principles. Our experienced Geologists and crew are available round-the-year for this purpose. If the client wishes, traditional water-divining techniques too can be employed.
In most cases, water well is needed to reach the aquifer where ground water is found. Today, most wells are made by drilling into the rock layers using drilling machines (rigs) to access water deep beneath the surface. In most cases electric pumps are used to raise the water to the surface.
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.
Rotary and DTH Rock up
to 500 ft. and Sedimentary and soil up to 1300 ft. 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 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 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
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.
Quality of Water
The quality of water from wells can be influenced by:
The quality of water from wells can be influenced by:
Natural factors, such as the type of rock, gravel, sand or soil, or by
pollution, for example, from poorly managed agriculture, inferior septic
systems or community waste disposal sites.
Public education about contamination, and community involvement in
protecting aquifers, can help ensure safe drinking water throughout the
United States.
It should be located and constructed in a manner which meets all the
codes and guidelines. Proper construction and location is of most
importance, to help ensure safe drinking water. Your County health
officers, local code enforcers and ground water contractors can give you
advice on proper well location and construction
If you plan wisely, good, dependable water well can supply you with all
the water you need now and in the future. A rule of thumb is to allow
for between 75 and 150 gallons per person each day. You need to take
into account the peak demand, for example, when there may be extra
guests.
The amount of water expected for domestic supply is usually 4-10 gallons
per minute. However, with an adequate storage tank, a well producing as
little as one gallon per minute can be sufficient for domestic needs.
In many wells, several hundred gallons of water are already stored in
the well column. For every foot of a 6 1/2" inch diameter well below the
water level, there are about 1 1/2 gallons of water.
High Quality Materials
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.
Full Service- Repair/replace pumps.
- Repair well plumbing.
- Down-the-Hole Hammer Drilling (DTH Drilling)
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.
