● Our core services
Our Borehole Drilling Services
We provide the core services required to develop and equip a new borehole, with the scope determined by the site and intended application.
Hydrogeological Survey & Borehole Siting
Before drilling begins, the site is assessed to establish its groundwater potential and identify a suitable location for the borehole. The survey provides the technical basis for planning the drilling works and gives an indication of the expected groundwater conditions at the proposed site.
Borehole Drilling
Drilling is carried out according to the geological formations encountered beneath the site.
The required depth is not assumed in advance. It is determined by the groundwater conditions encountered during drilling and the requirements of the project.
Borehole Casing & Construction
The drilled opening is constructed using suitable casing and screening arrangements to maintain the integrity of the borehole and allow groundwater to enter the well effectively.
The construction approach depends on the formations encountered and the characteristics of the borehole
Borehole Development
Once construction is complete, the borehole is developed to remove drilling residues and prepare the water source for testing.
This is an important stage between drilling and commissioning because the borehole needs to be in a suitable condition for its performance to be properly assessed.
Test Pumping
Test pumping establishes how the borehole performs under pumping conditions.
The results provide information on yield, water-level behaviour and the appropriate operating conditions, which can then inform pump selection.
Water Quality Testing
Groundwater quality varies between sites and should be established before the water is put to its intended use.
Water samples can be analyzed to determine the characteristics of the groundwater and whether treatment is required.
Borehole Pump Installation
The borehole requires an appropriately sized pumping system to bring groundwater to the surface.
Pump selection should correspond to the borehole’s tested performance and the property’s water demand rather than being based on a standard specification.
● Residential . Industrial . Institutions
Borehole Drilling for Different Water Requirements
Our residential borehole drilling solutions are made to prioritize your family’s health. Because domestic consumption is relatively low, we focus on cost-effective, compact designs using a standard 6-inch well diameter. We prioritize food-grade uPVC casings to maintain absolute drinking water purity and install quiet, highly efficient submersible pumps that easily integrate with your existing home storage tanks. Our drilling crews are highly trained to operate within tight suburban compounds, ensuring minimum disruption to your lawns, structures, and daily peace.
Residential borehole solutions can support:
Private homes • Residential compounds • Apartments • Gated communities • Residential developments
For apartment complexes, shopping malls, construction sites and factories, we design and drill wide-diameter, heavy-duty commercial boreholes designed to accommodate higher and more sustained water demands. These projects require high-capacity pumping systems and comprehensive test pumping to establish the borehole’s yield and performance under sustained abstraction. We also handle the commercial permitting and water-management requirements associated with the Water Resources Authority (WRA), helping businesses meet the applicable regulatory requirements while developing a dependable alternative or supplementary
Commercial borehole solutions can support:
Apartment complexes • Hotels • Offices • Shopping centres • Construction sites • Factories • Industrial facilities
Agricultural operations require massive volumes of water to keep crops thriving and livestock healthy, but running high-capacity electric pumps on grid power can quickly ruin a farm’s profitability. Our agricultural borehole solutions focus on deep-aquifer targeting to guarantee a high continuous yield throughout Kenya’s unpredictable dry seasons. We specialize in matching these high-volume wells with large-scale solar water pump installations, allowing you to pump thousands of liters of water into elevated reservoirs using free daylight. This design is an incredibly sustainable investment for horticultural fields, flower farms, and ranches.
Agricultural borehole solutions can support:
Irrigation • Horticulture • Floriculture • Livestock farming • Mixed farms • Ranches • Agricultural developments
Schools, hospitals, churches, and government facilities face strict public health standards and require an absolute guarantee of uninterrupted water supply. Institutional borehole drilling demands an intense focus on public safety and high-capacity water treatment, including multi-stage filtration, chlorination, or reverse osmosis systems to eliminate bacterial threats. We collaborate closely with board members, donors, and local government bodies to manage the strict National Environment Management Authority (NEMA) Environmental Impact Assessments required for public sites. Our systems are built for long-term durability and ease of community maintenance, ensuring safe water flows for hundreds of people daily.
Institutional borehole solutions can support:
Schools • Hospitals • Universities • Churches • Government facilities • Community facilities • Residential institutions
● Complete water-system integration
From Groundwater Source to Working Water System
Depending on the application, Trelan Engineering can integrate the borehole with other components required to make the water source useful across the property.
Borehole Pumps
Submersible pumping systems designed around the borehole’s characteristics and required water supply.
Booster Pumps
Additional pumping where greater pressure is required to move water through the property’s distribution system
Water Treatment
Treatment systems selected according to the quality of the groundwater and the intended use.
Solar Water Pumping
Where appropriate, the borehole pumping system can be integrated with solar power to provide an alternative source of energy for water abstraction.
● Tapping your underground supply
What Determines Borehole Depth?
Groundwater conditions vary considerably between locations, so the depth reached by one borehole does not necessarily indicate the depth required on another property. The eventual drilling depth can be influenced by:
- the local geology;
- the location and characteristics of the aquifer;
- the groundwater conditions encountered during drilling;
- the required water yield;
- the intended application; and
- the construction requirements of the borehole.
