Borehole Drilling

Alimi G. Global Enterprises Ltd Borehole Drilling Service manages every aspect of your Borehole Drilling including scheduling, estimating, budget control, value engineering, sub-contractor bid solicitation, on-site supervision, quality control, cost control, safety monitoring, total project management and a commitment to delivering expert approach and exceptional value. The Company also provides consultancy services and bespoke products based on customers demand.

Our Boreholes Drilling service starts from the initial step like surveying the site to completing the work. We use the latest equipment. The drilling operations will be taken up with combination rigs mounted on trucks with ELGI 1100/300 model compressors to a depth of 300 meters. The company ensures supply of spares and tools as per the requirement and the work will be completed on schedule.

Our Service Includes:

  • Geophysical Survey
  • Borehole Drilling
  • Borehole Rehabilitation
  • Mining
  • Core Drilling
  • Hand Pumps Supply and Installation
  • Pump Testing
  • Submersible Pumps Supply and Installation

Our Borehole Drilling Process

Borehole Drilling

Step 1 - Hydro-geologists site the borehole
The very first thing that needs to be determined is where the water is, and how we are going to get to it. Thats why we employ hydro-geologists who make use of a variety of borehole drilling methods to assess the geophysical properties of the underlying area. These are the guys that help us ensure we are not drilling into natural hazards (such as faults or fractures) or manmade infrastructure (pipelines, cables, phone lines, etc).

Step 2 - Drilling and Construction
Once the hydro-geologists have helped us prep a path for borehole drilling, we follow through and construct the borehole. It is not as easy as Moses and the rock, unfortunately, and, contrary to popular belief, an endless supply of water will not just surge to the surface following the drilling of the borehole; there are still steps to follow and processes to be completed. Once the borehole has been drilled the necessary unstable lengths of the borehole are steel cased in an effort to reinforce the tube.

Step 3 - Determining the yield of the borehole
In order to most accurately gauge the yield of a domestic water borehole an aquifer test is performed. This involves installing a test pump and pumping borehole water for a fixed set of variables; a given time at a given rate, and then assessing the tests impact on the water level in the borehole. Maximum yield is achieved by increasing the abstraction rate, ensuring optimum drawdown of water in the borehole.

Step 4 - Pumping and piping the borehole
The kind of pumping system and piping installed in your new domestic water borehole will largely depend on the intended use of the borehole water.
