GEOPHYSICAL WATER SURVEYING
– Conducting a geophysical water survey is crucial before drilling a borehole to identify the optimal drilling site.
– Our machinery specifications dictate effective surveying methods to establish suitable locations for borehole drilling.
– The first approach involves long-range surveying, allowing us to determine the desired depths for locating fault zones.
– Typically, this first method operates within a horizontal range of 400 meters and a vertical range of 150 meters.
– This technique identifies two cross-directional intersections where the fault zone converges at the center.
– The fault zone refers to porous rock formations that potentially permit the flow of water if present.
– The second stage occurs after identifying the fault zone, utilizing electrical resistivity survey methods.
– This method assesses the depths of potentially porous rocks that may allow water infiltration into the borehole.
– The machine can identify up to three potential fracture zones, indicating expected water depths.
– It is important to note that depth predictions are not always accurate, and we may need to drill at least 30 meters deeper than the third suggested fracture zone; the machine does not measure water quantity, which varies by area.
BOREHOLE DRILLING
– After identifying the drilling location, we can initiate the drilling process using the air percussion method.
– We have three types of machinery available: a small portable drill rig capable of drilling up to 80 meters for areas with limited access, a trailer drill rig that can reach depths of 120 meters, and a truck drill rig suitable for larger sites, capable of drilling up to 200 meters.
– The mentioned drilling method serves as a standard approach; however, each machine has distinct pricing and operational techniques.
– The drilling process involves utilizing a combined clay cutter and DTH hammer to create a hole that accommodates the insertion of steel or PVC casings once medium to hard rock is encountered.
– The casings are installed beyond the hard rock layer to prevent the collapse of the borehole due to unconsolidated rock in the top section.
– Once the top-hole casings are securely in place, we can continue drilling until we reach the desired depth or achieve an adequate water flow.
– During the drilling process, we assess the stability of the ground formation by observing characteristics of softer ground deeper within the borehole, beyond the steel casings.
– At this point, we can evaluate the necessity of installing PVC screen casings; however, we generally recommend their installation as a precaution against potential future ground movement and collapse.
– Upon completion of drilling, we will conduct a borehole blowout, which serves to clean the borehole and estimate the expected water yield.
– This process ensures that we achieve our objective of determining the borehole’s capacity for water extraction effectively.
BOREHOLE YIELD TEST
– At this phase, we will conduct the pumping test, also known as the yield test.
– A pumping test involves installing a pump in the borehole to extract water at various levels and flow rates.
– The purpose of this test is to assess the borehole’s capacity to deliver a specified volume of water per hour.
– This assessment will help determine the appropriate pump size needed for scenarios requiring significant daily water extraction.
– Additionally, the test ensures that the installed borehole pump does not exceed the borehole’s yield capacity per hour.
– The duration of the pumping test can be customized, typically ranging from 2 hours to as long as 76 hours, based on the intended use of the borehole water.
– During this stage, water samples can be sent for laboratory analysis if necessary, to comply with SANS 241 standards for drinking water.
– Based on the laboratory results, we can recommend suitable filtration methods to ensure water quality.
– This process is crucial for optimizing water extraction while maintaining the sustainability of the borehole.
– Proper execution of the pumping test is essential for effective water resource management and ensuring safe drinking water standards.
BOREHOLE pump installation
– After assessing the estimated yield from the borehole blowout or verifying it through a pumping test, we will proceed with the installation of the motor and pump.
– All necessary fittings and cables will be provided according to the client’s specifications and water usage requirements.
– If electrical supply to the borehole is required, the client has the option to collaborate with their chosen electrician or engage our services for an additional charge.
– Upon installation of the pumps, clients may choose to add motor protection automated control boxes for an extra fee, unless this was already included in the initial quote.
– These control boxes are specifically designed to safeguard the borehole motor from potential issues such as under-voltage, over-voltage, overload, or under-load conditions.
– They also prevent damage by ensuring that the motor does not operate when the borehole is dry.
– The control system can be programmed to operate at designated intervals, restarting the pump once the borehole is replenished.
– Following the installation, we will conduct tests to ensure that all systems are functioning properly.
– This comprehensive approach ensures both operational efficiency and customer satisfaction.
– Our team is available to accommodate any further modifications or requests after the installation.
– Our team is ready to accommodate any additional modifications or requests following the installation.
– Our team is committed to delivering high-quality service and support throughout the installation phase.
Water quality testing
– After pumping the water, we can collect samples for analysis at an accredited laboratory.
– The laboratory will test the samples to determine if they comply with SANS 241 standards.
– If the water fails to meet these standards, we will recommend appropriate filtration methods to ensure compliance.
– Following filtration, the water samples must be resubmitted for testing.
– Compliance with SANS 241 is crucial for ensuring the water is safe for drinking.
– Meeting these standards also prevents potential damage to household plumbing systems, including geysers and washing machines.
– Ensuring water quality provides clients with peace of mind regarding their water supply.
– It reduces reliance on municipal water sources that may not be safe for consumption.
– Adhering to SANS 241 standards helps maintain the integrity of household water systems.
– Ultimately, it ensures that the water is suitable for both drinking and domestic use.
Municipality Back Up
– Tank sizes and pressure pumps can be tailored to meet individual client specifications, household dimensions, water consumption needs, and electrical requirements.
– Certain pressure pumps are designed to operate with solar backup, ensuring functionality during power outages.
– The system includes an automatically filling tank that replenishes when municipal water is available.
– This stored water can be accessed during interruptions in the municipal supply, ensuring a continuous water flow.
– A pressure sensor detects the failure of municipal water and activates the pump to maintain supply.
– The system relies on municipal water, which fills the tank for later use.
– The pump facilitates the transfer of water from the tank back into the main supply as needed.
– The stored water is suitable for all household applications, providing versatility in usage.
– This setup is highly recommended to mitigate the challenges posed by water supply disruptions.
– Under optimal conditions, chlorinated municipal water can be stored for long durations without quality degradation.
