Conducting Geophysical Survey: The process begins with conducting a geophysical survey to gather data about the subsurface. Geophysical methods, such as electrical resistivity, ground penetrating radar, or seismic surveys, are used to measure and interpret variations in subsurface properties, such as rock types, water-bearing formations, and depth to groundwater.

Data Interpretation and Analysis: The collected geophysical data is then analyzed and interpreted by geophysicists or hydrogeologists. They examine the data to identify potential groundwater-bearing formations, depth variations, and other geological features that may affect borehole siting.

Selection of Potential Borehole Locations: Based on the interpretation of geophysical data, potential borehole locations are identified. These locations are typically areas where favorable geological conditions, such as aquifers or permeable formations, are likely to exist. Factors like proximity to demand points, accessibility, and land ownership may also be considered during this process.

Ground Truthing and Verification: The identified potential borehole locations are further verified through ground truthing. This involves conducting on-site investigations, such as geological mapping, soil sampling, and hydrological surveys, to validate the geophysical findings and refine the selection of the most suitable borehole location.

Preparation of Survey Report: Once the potential borehole location is finalized, a survey report is prepared. The report includes details of the geophysical survey, the interpretation of the data, the rationale behind the borehole siting, and any relevant technical recommendations. The report also outlines the estimated drilling depth based on the interpretation of the geophysical data and the intended purpose of the borehole.

Presenting the Survey Report to the Client: The survey report is then presented to the client or the relevant stakeholders, such as a water management authority or a project manager. The report provides them with a comprehensive understanding of the site selection process, the geological considerations, and the recommendations for drilling.

Drilling the Recommended Depth: Once the client approves the borehole siting and recommendations, the drilling process begins. Drilling companies or specialized contractors carry out the drilling operations, following the specifications outlined in the survey report. The borehole is drilled to the recommended depth, considering factors such as the desired water yield, aquifer characteristics, and local drilling regulations.

It's important to note that this process may vary depending on specific project requirements, local regulations, and the expertise of the involved professionals. Each borehole siting project should be tailored to the site's unique geological and hydrogeological conditions to ensure the best chances of locating a productive and sustainable water source.

After considering factors such as the desired water yield, aquifer characteristics, and local drilling regulations, I choose my backyard as the best location for my borehole. QED

Before a geophysical survey is done at all, there is something called feasibility studies. If you inform us to site the borehole somewhere, ours is to conduct the feasibility study on the exact place, and if it wouldn't be a good prospect, then we look for another point to sound.

It's fun but challenging!



I no like stress

Yes it is challenging as you have said
