The following are the Most Important Factors that impact Borehole Installation Cost:
- Depth of the borehole
- The machinery, manpower and materials
- Type of ground
- The purpose for the borehole
The type of ground and geology of the site where you want to drill a borehole are the biggest factor that will impact the Borehole Installation Cost. It is very important to have a well experienced borehole professional doing the geology research of the site correctly, whether it’s rock, sand or clay you are dealing with.
Another central factor will be the depth of the borehole, as the groundwater will flow differently at different locations. This again can be found by the research done by the geology prospector, so experience is key in order to get the most accurate estimates as possible.
What is the purpose of drilling a borehole?
There are not a one size-fits-all borehole solution. Hence Borehole Installation Cost differs. This also affect the water quality needed and the processes used to sink a borehole. All the above-mentioned factors will then depend on which materials, machinery and what manpower is needed to get the borehole drilled.
Materials will include the physical construction for the borehole, machinery is the actual drill and the manpower is how many people you need to drill your targeted specific borehole.
The Basic Components for Calculating Borehole Installation Cost:
- Siting the borehole location – Locating the best spot to drill a borehole that will have the best performance and water quality at the lowest cost possible.
- Mobilisation and Demobilisation– Machinery, equipment and materials need to get to the site to be set up. This is the cost for moving the borehole drilling machinery and equipment to and from the site.
- Borehole Installation Cost per meter– As clarified above, every borehole will have a different depth depending on all the factors. The actual borehole drilling costs are usually calculated at a per meter cost. So, the depth and type of ground play the biggest role in getting a cost per meter.
- Construction Material Costs– After the borehole has been drilled, the casing and completion tasks needs to be implemented. This cost includes materials like a solid casing, screen, gravel pack, sanitary seal and a well head.
- Performance and Quality testing– The next step is well development, pump test and borehole water quality. That will determine how much water is available and the quality of the water.
- Platform and Pump– Once everything has been finished, the borehole needs a platform and pump installed for it to be used. It depends on what the use is for the borehole to decide whether it will be hand pump or electrical pump.
This are the basic factors, processes and components that need to be included when calculating the Borehole Installation Cost.
