4. THE COMPLETE BOREHOLE DRILLING PROCESS: FROM SURVEY TO WATER SUPPLY
A complete borehole project involves a series of technical and operational stages. Each stage contributes to the quality, safety, efficiency and long-term performance of the water supply system.
4.1 INITIAL CONSULTATION AND WATER REQUIREMENT ASSESSMENT
The first step is establishing why the customer requires a borehole and how much water the project is expected to consume.
A borehole designed for a family home will have different requirements from one intended for a commercial farm, hotel, school, hospital or industrial facility.
We assess the intended water application, the number of users, daily demand, peak demand, operating hours, available land, proposed storage capacity and distribution requirements.
For agricultural properties, the assessment also considers cultivated acreage, irrigation methods, crop water requirements, livestock numbers and seasonal water demand.
For commercial and industrial facilities, the assessment considers production activities, cleaning, cooling, sanitation, process water and future expansion.
The information collected at this stage helps determine the scope of the groundwater investigation and the appropriate water infrastructure design.
4.2 SITE VISIT AND PHYSICAL INSPECTION
A site visit allows the technical team to evaluate the proposed drilling location and determine whether the property can accommodate drilling operations.
The inspection considers access roads, working space, ground stability, overhead electrical cables, underground utilities, neighbouring structures, sanitation facilities, drainage and environmental conditions.
The proposed drilling position should also allow sufficient space for the drilling rig, compressor, support vehicles, drilling rods and construction materials.
Sanitary protection is particularly important. The proposed borehole location must be assessed in relation to septic tanks, soak pits, wastewater channels, fuel storage areas, livestock enclosures and other potential contamination sources.
The physical inspection also helps determine the practical route for future water pipelines, storage tanks, water towers and electrical installations.
4.3 HYDROGEOLOGICAL SURVEY
A hydrogeological survey investigates the geological and groundwater conditions of the proposed drilling location.
The investigation examines the relationship between subsurface formations, groundwater storage, groundwater movement and potential recharge conditions.
The assessment may consider volcanic formations, weathered rock, fractured bedrock, sedimentary deposits, alluvial materials, faults, joints and other geological structures.
In fractured-rock environments, groundwater may occur within interconnected fractures and weathered zones. In unconsolidated formations, groundwater may move through pores between sand and gravel particles.
The hydrogeological assessment may include reviewing existing borehole records, geological information, groundwater levels, local water points and available geological maps.
The purpose is to establish the likely groundwater conditions and develop a technically informed drilling recommendation.
4.4 GEOPHYSICAL GROUNDWATER SURVEY
Geophysical investigation provides additional information about the subsurface without initially excavating or drilling the ground.
Electrical resistivity methods are commonly used for groundwater exploration.
During a resistivity survey, electrodes are placed into the ground and controlled electrical current is introduced. The resulting electrical potential differences are measured and processed to calculate apparent resistivity.
Different geological materials exhibit different electrical properties depending on their composition, moisture content, porosity, clay content, mineralisation and groundwater conditions.
Survey methods may include Vertical Electrical Sounding (VES) and Electrical Resistivity Tomography (ERT).
VES investigates changes in apparent resistivity with increasing electrode spacing, while ERT can provide a two-dimensional or three-dimensional interpretation of subsurface resistivity variations.
The resulting interpretation may help identify weathered formations, fractured rock, possible saturated zones and geological boundaries.
Borehole RestorationHowever, low electrical resistivity does not automatically indicate a productive freshwater aquifer. Clay and saline groundwater can also produce low resistivity values. Geophysical interpretation must therefore be combined with geological and hydrogeological information.
4.5 SURVEY REPORT AND DRILLING RECOMMENDATIONS
Following the investigation, the findings are documented in a technical report.
The report may include the site location, survey methodology, geological interpretation, resistivity data, recommended drilling position, anticipated formations, proposed drilling depth range, construction recommendations and relevant groundwater observations.
The report provides the technical basis for planning the drilling operation.
The recommended depth and potential yield remain estimates until the actual geological formations are encountered and the completed borehole is tested.
4.6 APPROVALS AND REGULATORY COMPLIANCE
Groundwater development must comply with applicable Kenyan water resource and environmental requirements.
The project team should establish the required Water Resources Authority approvals, groundwater development documentation, professional supervision requirements and applicable environmental approvals before drilling.
The required documentation may include hydrogeological reports, geophysical survey reports, drilling applications, environmental documentation, drilling records, pumping test results and water abstraction permit documentation where applicable.
The approval requirements depend on the project and the applicable regulations.
4.7 DRILLING EQUIPMENT MOBILISATION
Once the project is planned and the required authorisations are established, drilling equipment is mobilised to the site.
The equipment may include drilling rigs, compressors, drilling rods, drill bits, casing materials, support vehicles, water supply equipment and other necessary tools.
The drilling platform is prepared, the rig is positioned and safety arrangements are established.
The drilling method is selected according to the geological formations anticipated and the technical specifications of the project.
4.8 BOREHOLE DRILLING
Borehole drilling involves penetrating the subsurface to intersect groundwater-bearing formations.
Rotary drilling, air rotary drilling and down-the-hole hammer drilling may be used depending on the geology and project requirements.
As drilling progresses, the drilling team records the formations encountered, drilling depth, changes in rock type, weathered zones, fractured formations and groundwater strike observations.
A water strike indicates groundwater entering the borehole during drilling. It does not by itself establish the sustainable yield.
The final borehole performance must be determined through development and pumping tests.
4.9 GEOLOGICAL LOGGING
Geological logging records the formations encountered during drilling.
The record may include soil types, rock formations, weathered zones, fractured formations, water strike depths, drilling conditions and other construction observations.
This information assists in determining the appropriate casing and screen arrangement.
4.10 CASING AND SCREEN INSTALLATION
Borehole casing provides structural support and helps prevent collapse of the borehole.
Depending on the geological conditions, the construction may incorporate suitable uPVC or other approved casing materials.
Screen sections are installed where groundwater needs to enter the borehole through designated openings while controlling the movement of formation particles.
The screen slot size must be selected according to the formation characteristics and construction design.
Gravel packing may be installed around the screened sections where specified.
The annular space must also be sealed appropriately to protect the borehole against unwanted surface water entry and potential contamination.
4.11 BOREHOLE DEVELOPMENT
After construction, the borehole is developed to remove drilling residues, fine particles and accumulated materials.
Development techniques may include airlifting, surging, pumping and other suitable mechanical methods.
Proper development helps improve groundwater entry into the borehole and reduce excessive sediment production.
The development process should continue according to the observed water clarity, sediment conditions and technical requirements.
4.12 PUMPING TESTS AND YIELD ASSESSMENT
A pumping test establishes how the borehole responds when water is abstracted at controlled rates.
The test may involve step-drawdown pumping, constant-rate pumping and recovery monitoring.
The important measurements include:
- Static water level.
- Pumping water level.
- Drawdown.
- Discharge rate.
- Specific capacity.
- Recovery behaviour.
- Pumping duration.
These measurements help establish the borehole's tested performance and inform the recommended abstraction rate.
A borehole should not be equipped with a pump that abstracts water at a rate greater than the technically established and authorised operating capacity.
4.13 WATER QUALITY TESTING
Groundwater quality must be assessed before deciding whether it is suitable for drinking, irrigation, industrial operations or other uses.
Testing may include physical parameters such as colour, turbidity, odour, electrical conductivity and total dissolved solids.
Chemical analysis may include pH, hardness, calcium, magnesium, chloride, sulphate, nitrate, fluoride, iron and manganese.
Microbiological testing may include total coliforms and Escherichia coli.
The results determine whether filtration, disinfection, softening, iron removal, reverse osmosis or other treatment processes are necessary.
4.14 SUBMERSIBLE PUMP INSTALLATION
After the borehole yield and operating water level are established, the appropriate pump can be selected.
Pump selection considers borehole depth, static water level, pumping water level, required discharge, total dynamic head, delivery pressure, pipeline friction losses and power availability.
A complete pump installation may include the submersible pump, motor, rising main, electrical cable, cable joints, non-return valve, safety arrangement, control panel and protective equipment.
The pump must be installed at an appropriate depth to maintain the required submergence while avoiding unsuitable proximity to the borehole bottom and sediment accumulation.
4.15 SOLAR-POWERED WATER PUMPING
Solar-powered pumping is suitable for many agricultural, residential and rural water supply applications.
The system may include photovoltaic panels, mounting structures, a compatible solar pump controller, submersible pump, electrical protection, sensors and water storage.
Solar system sizing considers the required daily water volume, pumping head, solar resource, equipment efficiency and expected operating conditions.
Where appropriate, water can be pumped into storage during available sunlight, reducing the need for battery storage.
4.16 ELECTRICAL INSTALLATION AND AUTOMATIC CONTROL
A complete borehole installation requires appropriate electrical protection and control equipment.
We provide electrical systems for pump operation, including motor protection, overload protection, phase protection where applicable, dry-run protection, automatic water level controls and pump control panels.
Automatic controls can monitor tank levels and initiate or stop pumping according to programmed operating conditions.
For suitable applications, variable frequency drives can be incorporated to regulate pump speed, subject to motor compatibility and manufacturer requirements.
4.17 WATER STORAGE AND TOWER INSTALLATION
Water storage provides a reserve between pumping operations and actual consumption.
Storage solutions may include ground-level tanks, elevated tanks, steel tanks, polyethylene tanks and multiple interconnected storage units.
The required capacity depends on daily water demand, pumping hours, peak consumption, available borehole yield and reserve requirements.
Where gravity-fed distribution is required, an elevated water tower can provide the necessary hydraulic head.
Tower design must consider structural loads, foundations, height, tank capacity, wind loading, access and safety.
4.18 WATER PIPELINE INSTALLATION
The final water distribution network connects the borehole or storage facility to the consumption points.
We provide HDPE and PVC water pipeline installations, rising mains, distribution branches, isolation valves, non-return valves, pressure control equipment, water meters and irrigation connections.
Pipeline diameter is determined using the required flow rate, pipe length, friction losses, pressure requirements and elevation differences.
For farms, the distribution network can supply irrigation blocks, greenhouses, livestock facilities and farm buildings.
For residential and commercial properties, the network can supply kitchens, bathrooms, laundry facilities, external taps and other consumption points.
4.19 WATER TREATMENT AND PURIFICATION
Where laboratory analysis identifies water quality concerns, a suitable treatment system is incorporated.
Treatment options may include sediment filtration, activated carbon filtration, iron removal, manganese removal, water softening, reverse osmosis, chlorination and ultraviolet disinfection.
The treatment sequence must be designed according to actual laboratory findings and the intended water application.
4.20 FINAL COMMISSIONING AND WATER SUPPLY HANDOVER
The final stage involves testing the completed water supply system.
Commissioning may include pump performance checks, flow measurements, pressure checks, electrical protection verification, automatic control testing, tank filling tests, pipeline leak inspections and water treatment verification.
Relevant operating instructions, equipment details and maintenance recommendations should be provided to the customer.
The objective is to deliver an integrated and operational water supply installation from the groundwater source to the final delivery points.
