Borehole Drilling in Zimbabwe is the leading Borehole Drilling consultancy in Zimbabwe.

Borehole Drilling in Zimbabwe has extensive knowledge in the field of Borehole Drilling and understand the requirements of specific customers as well as projects. Borehole Drilling in Zimbabwe has been involved in a number of projects involving evaluation, baseline studies, feasibility studies, environmental impact assessment, project design and proposal development, community need assessment etc.

1. Geological Survey or Borehole Siting: After the contract has been formalized, our technical team will visit the site along with geologists to identify the best place to carry out the drilling process.

2. Borehole Drilling: The drilling is carried out by using the “Down-The-Hole” technology. This system works by using highly compressed air built within our drilling rig. The size of the hole can vary depending on the requirement of the client. As the drilling process continuous, geological rock samples are taken at 2-meter intervals. Struck and water rest levels are constantly recorded. This process enables us to estimate the yield of individual aquifers encountered.

3. Borehole Casing: Once the borehole has been drilled, it must be lined with either steel or UPVC casing. The casing process keeps the Borehole open and protects the earth, similar to the efforts to protect groundwater.

4. Borehole Development: Once the screen, pack, seals and backfill have been installed, the Borehole is developed. This development aims at repairing the damage done to the aquifer during the course of drilling by removing clays and other additives from the borehole. This also alters the physical characteristics of the aquifer around the screen and removes fine particles.

Borehole Drilling Stages in Zimbabwe

The use of over-pumping as a means of development is not advocated since it only increases permeability in zones that are already permeable. Instead, we recommend mechanical surging with a plunger or the use of air or water jetting which physically agitates the gravel pack and adjacent aquifer material. This is an extremely efficient method of developing and cleaning wells.

5. Borehole Yield Testing: After development and preliminary tests, a long-duration well test is carried out. Borehole Yield Tests have to be carried out on all newly-completed wells, because not only does this give an indication of the success of the drilling, design and development, but it also yields formation on aquifer parameters which are vital to the hydrogeologist.

A Borehole test consists of pumping a well from a measured static water level (SWL) at a known or measured yield and recording the rate and pattern by which the water level within the Borehole changes. Once a dynamic water level (DWL) is reached, the rate of inflow to the well equals the rate of pumping. Today, it is a common practice to carry out a ‘step drawdown test’, in which the yield is increased stepwise. Each step is continued until hydraulic equilibrium is reached after which the yield is increased by 50 to 100%.

Towards the end of the test, a water sample of 2 litres is collected for chemical analysis. The duration of the test is 24 hours, with a further 8 hours for a recovery test (during which the rate of recovery to SWL I recorded). The results of the test enable the hydrogeologist to calculate the best pumping rate, the installation depth, and the drawdown for a given discharge rate.

6. Water Quality Test: Borehole Drilling in Zimbabwe has contracted well trained chemists that conduct water quality tests in the quest of knowing the status of total coliform bacteria, nitrates, total dissolved solids and pH levels. Where a client suspects other contaminants, Borehole Drilling in Zimbabwe also tests for such.

7. Borehole Pump Installation: Depending on the well testing report, Borehole Drilling in Zimbabwe installs motorized submersible pumps through its sister company; Borehole Drilling in Zimbabwe irrigation and Energy Services which specializes in pumps.
