Step-by-Step Borehole Drilling Process in Kenya: From Survey to Pump Installation
Water is life, but in many parts of Kenya, access to clean, reliable water is far from guaranteed. Droughts, water rationing, failing municipal systems, and expanding agricultural needs have pushed many Kenyans to consider drilling private boreholes. However, the process can…
Electromagnetic (EM) Surveys for Groundwater Exploration in Kenya
Electromagnetic (EM) methods have emerged as a powerful complement to traditional resistivity surveys across Kenya’s diverse terrains. Particularly valuable in the Rift Valley’s conductive sediments and coastal aquifers, EM techniques provide rapid, non-invasive subsurface profiling to depths exceeding 300m. This article…
Cost Differences in Hydrogeological Surveys Based on Location and Methodology in Kenya
Hydrogeological surveys are an essential prerequisite for drilling successful boreholes and developing sustainable groundwater resources. In Kenya, the cost of these surveys can vary widely depending on several factors, including geographical location, the specific survey methods used, depth of exploration, logistics,…
Geophysical Methods Used in Hydrogeological Surveys in Kenya: Focus on Electrical Resistivity
The accurate identification of groundwater resources requires more than surface observations—it demands insights into the subsurface. This is where geophysical methods become indispensable. In Kenya, one of the most widely used geophysical tools in hydrogeological surveys is the Electrical Resistivity Method…
Aquifer Types and Groundwater Occurrence in Kenya’s Geological Formations
Kenya’s diverse geology offers a wide array of aquifer systems, each with distinct characteristics influencing water yield, depth, and quality. From the fractured crystalline rocks of the highlands to the porous coastal sediments and volcanic aquifers of the Rift Valley, groundwater…
Environmental considerations in borehole drilling
Borehole drilling, like any subsurface activity, has potential environmental impacts that need careful consideration and management. Here are several key environmental considerations associated with borehole drilling: Surface Disturbance and Land Use: Vegetation Removal: Clearing of vegetation for access roads, drilling pads,…
What is well design and construction
Well design and construction refer to the process of planning, engineering, and implementing the infrastructure necessary to access groundwater or other subsurface resources safely and effectively. It involves several key steps and considerations: Well Design: Site Evaluation: Hydrogeological Assessment: Assess the…
Types of aquifers in borehole drilling
Aquifers are underground geological formations capable of storing and transmitting water. They are crucial for borehole drilling because they provide a sustainable source of groundwater. The type of aquifer encountered during drilling depends on the geological characteristics of the area. Here…
Factors to determine in site selection
Site selection for drilling operations, whether for water wells, geotechnical investigations, or other purposes, involves considering several critical factors to ensure the success and efficiency of the project. Here are key factors to determine during site selection: Geological and Hydrogeological Conditions:…
Role of geologists in borehole industry
Geologists play a crucial role in the borehole industry, contributing their expertise in earth sciences to various aspects of drilling projects. Their involvement spans from initial site assessment to post-drilling analysis and ongoing monitoring. Here are the key roles and contributions…
