The assessment generally includes a review of all available maps and other information in combination with field investigations such as: hydrogeological and geophysical field survey to identify sites for borehole drilling, topographic surveys, water quality measurements and river flow measurements.
Detailed data reviews are part of all investigations: through the available information, areas of promising groundwater potential are targeted for follow up during detailed geophysical field investigations. The review includes the analysis of available maps, climate data, satellite imagery, GIS, aerial photography, existing boreholes and database/statistical techniques.
Underground water typically occurs in relatively narrow aquifer zones, such as faults, fractures and cavities that have developed in the surrounding dry rock mass. While random drilling may result in a “lucky strike”, the chances of developing a successful borehole are considerably enhanced by using scientific methods. Aquaquest is specialised in the identification of productive aquifers zones through their well-tested hydrogeological-geophysical survey methodology. Aquaquest utilises specialised equipment for conducting electrical resistivity and magnetic surveys.
Aquaquest can carry out topographical surveys to collect coordinates and elevation data for points in the field. Interpolation between the measured points results in a detailed contour map of the area, or a profile along a selected transect (e.g. a proposed pipeline route or a water channel). The information gained from a topographical survey is critical in the design of dams, surface water reservoirs, piped water systems and many other civil works. Aquaquest uses modern technology, such as total station and differential GPS to collect topographic data with high accuracy.
For these services, Aquaquest offers you up-to-date date equipment, a range of methodologies to best suit your requirement and the specific environment, and a highly skilled team with many years of experience in Zambia and throughout Africa.
Proper construction and accurate testing results in an optimum borehole yield, improves the long-term pumping efficiency and extends the lifespan of your borehole. Aquaquest works with reputable and reliable drilling contractors to incorporate best practices, appropriate design and most suitable construction materials to ensure successful borehole completion.
Since its inception, Aquaquest has been providing professional drilling supervisory services to many companies that require additional expertise to drill boreholes. Our team will deploy on-site consultants and review borehole data on the spot, while ensuring application of best drilling practices to optimise the results of your drilling project, ensure best quality and value for money, and reduce the overall costs.
Before deployment to the site, Aquaquest will make sure that it fully understands the exact needs of our clients. The company will then carefully evaluate and assign the best team for your particular project. Their goal is to ensure the best drilling results, while reducing costs and time for the client.
Contact Aquaquest today and find out more about how they can assist you with your drilling programme. Their experienced drilling supervisors are your solution to ensure that your water requirement is met and the plan is carried out to the highest possible standard.
Boreholes in larger rural villages often come with a water reticulation system to distribute the water to several locations in the village. These systems tend to be relatively simple with an elevated water tank, pipework and water kiosks or stand taps. These simple designs can significantly improve the livelihoods, health and hygiene of poor rural communities. Aquaquest can help, by identifying a reliable source of water, designing the water supply system, aiding in the procurement of material and supervising the construction of a small-to-medium sized community water supply system.
Subsequently Aquaquest conducts and oversees appropriate borehole tests following internationally recognised test pumping procedures. This will help to identify the long-term sustainable yield and operating efficiency of a borehole and determine the most suitable pumping equipment to achieve this. To date, the company has overseen and carried out over 500 pump tests, providing its clients with recommendations on the most suitable type of pump, depth setting, pumping rate and installation.
The performance of a borehole depends on how the borehole was constructed, the design and the type of materials used. However, in many cases, this information is not available to the borehole owner! Over time, boreholes deteriorate due to silting, clogging of screens, and collapse (due to poor design).
Aquaquest can assess your borehole using their down-the-hole borehole camera, while reviewing the available drilling data, old and new test pumping records, and pump information. The use of a camera is the fastest and most cost-efficient way to determine what might be wrong with your borehole, and what can be done solve the problem.
With a highly skilled team and up-to-date equipment, Aquaquest provides professional in-house test pumping services and also oversees the test pumping procedure carried out by drilling contractors. This procedure is essential to determine the most suitable long term yield for your borehole, select the most appropriate pumping equipment. Robust scientific data will help you to know the reliable water yield from your borehole, select the most efficient pump, avoid over-pumping and ensure a reliable long-term supply of water.
Aquaquest will ensure that pumping tests are carried out to the highest quality at international standards. No matter the size of your project or where you are located in Zambia, the works will be completed efficiently and on time. Their professional team is always willing and happy to advise you on all aspects of groundwater development, efficient pumping and sustainable water supply.
