Borehole Drilling
We provide a world-class borehole drilling service to the industrial, commercial and domestic markets by utilizing the latest borehole drilling technology and machinery. We do Symmetric Drilling, Core Drilling and Geo-technical Drilling.
Borehole Drilling is carried out to satisfy the ever growing demand for water, mainly for domestic use, irrigation, industrial and livestock needs. Borehole drilling is mainly done efficiently using latest state of the art borehole drilling machines (known commercially as borehole drilling rigs). Manual borehole drilling is is also done using manual digging tools.
With years of experience in drilling and equipping OCTOPUS is one of the largest borehole drilling companies in Kenya.
Over the years, OCTOPUS has built a reputation as one of the best borehole drilling companies in Kenya and the entire East Africa. Being one of the leading well drilling companies in Kenya, we always strive to give our clients the best and prompt services. Our borehole drilling services in Kenya are top notch, always meeting customer needs.

Borehole Drilling Procedure:
1. Hydrogeological survey
This is to establish the soil formation, depth and location of where the actual drilling will be done. It also assists in getting the required government approvals such as NEMA and WARMA certificates.
2. Actual Drilling
Actual drilling involves machine (drilling rig) mobilization and drilling. Drilling begins from above ground upto the recommended depth by the hydrogeologist. During drilling, casing is also done using steel or plastic casings. Borehole casing helps in preventing the borehole from collapsing and prevents impurities from contaminating the borehole water.
3. Test Pumping
Once drilling is complete, test pumping is done to determine the borehole yield or capacity in m3 per hour (m3/hr) This is done by continuously pumping water out of the borehole for 24 hours. Test pumping also helps in selecting the right pump for the borehole.
4. Water Chemical Analysis.
This is done to determine the suitability of the borehole water for drinking, irrigation or any other use. Some boreholes produce pure neutral water while others may produce salty water which may require treatment before use.
5. Borehole Equipping.
This entails installation of pumps in the borehole. Electric submersible, solar submersible or diesel pumps may be installed depending on expert advise. Pipes immersed into the borehole may be uPVC pipes or HDPE pipes, depending on the depth.
6. Auxiliary Services
Includes optional extra services such as installation of pipes, plumbing, irrigation, tank tower construction, tank installation etc. There is a separate quotation for these services.
Requirements for Borehole Drilling:
In order to drill a borehole in Kenya, the following are required:
This is done to determine the underground water potential. A hydrogeology survey report will give an estimate of the drilling depth, site location and the nature of rock and soil formation which will assist in determining casing materials and the cost of drilling. This survey must be done with an independent, qualified and registered hydrogeologist.
Water Resource Authority is state cooperation that regulates use of all water resources. They issue borehole drilling license and authorize drilling once the hydrogeologist report is ready. For you to be licensed by the WRMA, an application needs to be done online or physically visit their offices located across the country. WRA gives authorization licenses which is a green light to drill a borehole. They then issue a water permit that gives you permission to access the water resources as much as you want.
This assesses the effect of drilling on the environment. The report gives both positive and negative impacts on the environment incase drilling is done. If the project will not have negative impacts that may be hazardous to the environment, then a green light permit is given by them
Once all the above are met, drilling will proceed.
