Borehole Drilling Process: A Beginners Guide



Water shortages in most urban areas in Zimbabwe have driven the need for alternative water sources.

Select a contractor

A lot of money goes into the drilling of a borehole with most Zimbabwean borehole drilling companies charging upwards of USD$1300, we can all agree that is quite the large sum of money for most. It is therefore important to exercise due diligence when choosing your contractor. Consider factors such as reputation, look them up online, enter their name into search engines, ask for references and follow up, take your time, compare at least three quotes for the best deal and you will be good to go!

Sitting Borehole Location

This job is done by the hydrogeologist, who determines where the water is and how it will be accessed at the lowest cost. This is a very important step as it reduces the costly risks of drilling into water and sewer lines.

Drilling & Construction Of Borehole

Once the hydrogeologist points out the ideal location the next step can begin. This step requires due diligence in proper borehole design, professional construction and careful drilling. Basically, your contractor will drill a vertical hole, insert borehole casings to support the borehole wall, set up a borehole well screen to allow clean water from the aquifer to enter the borehole.. Ensure that the borehole driller uses Proplastics quality borehole casings which will last you a lifetime.

Borehole Cleaning

At this point your borehole will be a muddy mess littered with debris from the drilling process such as caked mud, dirty water and oil from the drilling rig. The cleaning process allows all these to be removed and your contractor will employ one of several methods to do this. After the cleaning has been done, a sanitary seal is placed on the borehole to deter further contamination of the water source.This step is critical as it ensures the smooth performance of the borehole and water quality.

Pumping & Piping Borehole

This is the final stage and the type of pump system installed will be determined by several factors such as the yield of the borehole and your needs.
