Groundwater Survey Processes
Discover Our Innovative Approach to Drill Site Location Surveys
Groundwater Surveys specialises in borehole or well water detection in both Agricultural and Industrial as well as Residential & Urban Groundwater Exploration
Borehole or Well Water Detection Process
Save Time and Money - Locate The Water Before You Drill!
Desktop and Field surveys are conducted for both Residential/Urban and Agricultural/Industrial surveys
Residential & Urban Survey Process
Desktop Survey
- The first step in this process is a thorough desktop study, which involves analyzing all available maps and aerial photos to identify potential groundwater structures.
- Upon request, an intensive study of the desired location can be done.
- The final report includes four digital maps and a conclusive water resource map in electronic format.
Field Survey
- Where groundwater is relatively easy to find, complex siting techniques are not cost-effective.
- Infrastructure in urban areas (such as electrical cables, telephone lines, buildings, and pipelines) can create interferences for geophysics, making interpretation of results difficult.
- Meaningful geophysical surveys require areas of several hectares of open ground, making property size a contributing factor.
- Water diviners are a popular method in urban areas.
- Groundwater Surveys uses an imported state-of-the-art water detection device designed by a German Engineering Company, with an accuracy of 85%-90% in locating underground water sources in urban areas.
- A sufficient number of soundings covering all potential groundwater bearing structures identified by the desktop study are then conducted.
Agricultural & Industrial Survey Process
Desktop Survey
- Our desktop study utilises advanced remote sensing techniques to analyse all geological, topographical, and geohydrological maps, including aerial photos, to identify potential groundwater sources for targeted ground geophysical surveys.
- With a special focus on the desired location, an intensive desktop survey of the entire farm/industrial site can also be done on request.
- Our comprehensive desktop survey report includes four digital maps (A1) and a conclusive "water resource map" in electronic format, providing you with valuable information for your drilling project.
Field Survey
- Groundwater Surveys makes use of a Geophysical Instrument that measures the variations of natural electric fields of subsurface geological structures, thereby identifying fractures in rock formations and other anomalies like possible dykes, faults, contact zones etcThe built-in computing functions collect data for a 2D subsurface profile map, showing potential subsurface water, fractured rock, and depth.
- Measurements cover all potential groundwater bearing structures identified in the desktop study.
- The final report estimates minimum and maximum depths of water-bearing rock formations.
- Electrodes record signals and take 32 measurements per point, with at least 1440 readings recorded for each site.
- The data is processed into a resistivity curve graph and 2D subsurface profile map.
