Water Well Drilling

PYRAMID Geo-Engineering & Construction Ltd. is one of the largest water well drilling contractors in Afghanistan. A fleet of 4 drill rigs of varying size and up to 500M vertical drilling capability insure that the company is prepared to meet practically any drilling challenge.

  The year 2012 marked 8 years of our successful experience in Water Well Drilling and Geotechnical Investigations in Afghanistan.   Water wells for domestic and agriculture use are our main focus, and we have the knowledge, experience and equipment to help you get the most out of the ground that Mother Nature laid down. Our drillers have been called on to help with difficult drilling projects in Afghanistan.

  You select the type of material for your wells, we will supply and install it for you; from PVC casing and screens to carbon black steel casings, and Johnson Screens are all available.

~       Cleaning and Developing Water Wells.  

 

Geophysical Survey:

  Wise using conserves underground water resources. In other words extraction and using of groundwater like other natural resources require prospecting, exploration development, exploitation and sound management; otherwise, it may lead to the waste of time and resources.  

  Geophysical Survey is an electrical method resistivity survey performed on site before drilling operations to determine the depth of aquifer layers, thickness of ground layers, extend of layers and to estimate the depth of the well according to the aquifer locations. 

 

   

 Bore Well Logging:

  The well logging is very essential to determine the geological formations of the borehole and aquifer layers of ground. This helps in sealing the salty layers, selection and correct installation of screens in the well and getting more fresh and healthy water from the ground.

  The log may be based either on visual inspection of samples brought to the surface called (geological logs) or on physical measurements made by electrical instruments lowered into the hole (geophysical logs). The types of instruments used in well logging are quite broad. The first logging measurements consist of basic electrical logs (resistivity) and spontaneous potential or self potential (SP) logs, introduced by the Schlumberger brothers in the 1920's. We can perform the geophysical logging as (resistivity-Res, Self Potential-SP and Gama) under the supervision of professional geophysical engineers.

 

Expert Drillers:

  The Pyramid Company recognizes that the success of its operations rests largely on the drillers operating in the field. Pyramid has an experienced team of drillers, whose skills and knowledge ensure safe, efficient and productive field operations.

 

Maintenance Staff:

  The Company recognizes that the success of its operations also rests on our maintenance staff. The drilling equipment is maintained in excellent working order to reduce the risk of breakdowns in the field. Our maintenance staff are qualified mechanics and available to give immediate back up support to the drilling operations.

 

Importance of Underground Waters & Protection:

  Groundwater is one of Afghanistan's most valuable natural resources, which is not efficiently used it is ignored like other natural resources, even though most provinces get their water from surface sources such as ditches, lakes and rivers, it is estimated that there is ten times as much fresh and high quality water below the land surface than in all the lakes and rivers combined. Groundwater is a far safer water source than surface water because it is protected by impermeable grounds like clay or rock, and is not so easily contaminated.

 

Groundwater Protection, How?

  Groundwater is one of the world's most important natural resources, yet most of us do little to protect it. The fact is, a great many of us rely on groundwater for drinking, domestic, agricultural and industrial uses. Our natural environment, such as streams, fish, and wildlife also depend on groundwater.

 

How Can It Get Contaminated?

  Groundwater is very susceptible to contamination, unless protected by a low permeability layer such as clay. Potential sources of contamination include:

~       Malfunctioning household septic systems

~       Careless disposal of cleaners, oil and antifreeze

~       Improper application of fertilizers and pesticides

~       Leaks from oil and chemical storage tanks

~       Industrial leaks and spills

~       Improper animal manure storage

~       Landfills and garbage dumps


How to be sure the water you drink is safe and clean?

  Fortunately, there are many things you can do to start protecting your groundwater resource. The time to start is now!
  Properly constructed water well is the best way to insure that the water you drink is safe and clean!

Submersible Water Pumps:
  Since our profession is well drilling and installation, so we better know how and where to install the submersible pump in the well. We will provide you with the best technical practices to install new pumps, repair existing pumps or change your submersible pumps.
