Our Services

We offer a complete service which covers all aspects of borehole design, drilling,
groundwork, pump installation and any type of water treatment services.



Nearly 13 million Kenyans use a borehole for their water supply. One of the key features of the unit that allows them to do this is the submersible pump. If you want to install a pump in your home or have one that needs replacing, GSI can help. Our expert plumbers have extensive knowledge and experience dealing with many different types of borehole pumps.

Common Signs of a malfunctioning pump are; Abnormal noises Dirty water Unusually high electric bills Air “spitting” from the faucet .


A number of reasons can cause such problems. One particular issue is age. Most common borehole pumps last a home anywhere from 3 to 5 years. If the device is old, you will need to replace it and install a new pump. Our qualified plumbing experts can help. We have so much experience installing and replacing borehole pumps, we can do it with our eyes closed – though we won’t!

  • Borehole Drilling Environmental Impact Assessment


Environmental Impact Assessment (EIA) is an integral part of planning and development. It is a process by which the anticipated effects on the environment of a proposed development are measured to inform the decision making process.

Our EIA team brings an enviable skill set encompassing strategy, planning, technical and environmental expertise, and is made up of professional Chartered Environmentalists, town planners, environmental scientists, ecologists, GIS and project managers, making us the natural choice to meet all of your EIA needs.

Our approach is to focus the EIA process upon the key issues and take a proportionate approach to the assessment to minimise project risk and maximise opportunities for success.
