Turnkey Water & Solar Project Delivery in Kenya
A complete water-solar project means one team drills your borehole, installs your pump, sizes and mounts your solar panels, constructs your storage tank, installs your water treatment system, and commissions everything together — with a single project manager, a unified design, and one warranty covering the entire system.
This is the most impactful offering Vajra Drill provides. The reason is straightforward: in Kenya, reliable water and reliable energy are often the two biggest constraints facing a farm, school, clinic, or institution. Solving both simultaneously, with a system specifically designed so that each component reinforces the other, delivers more value than any amount of incremental upgrading of separately procured systems.
Our complete project packages are used by commercial farms that need both water pumping and irrigation power, schools and hospitals that need potable water and uninterrupted electricity, NGOs delivering community water-energy access projects, and off-grid lodges and institutions where grid connection is impractical or prohibitively expensive.
What a Complete Project Includes
Every complete water-solar project is designed from scratch to meet your specific water demand and energy requirement. The scope varies by client, but a full turnkey package typically includes all or most of the following components.
Hydrogeological Survey & Borehole Drilling
Site survey using Vertical Electrical Sounding or ERT to identify the best drilling location. DTH or rotary borehole drilling to the required depth, casing installation, borehole development by airlift pumping, and yield testing with a full WRA completion report and abstraction licence application.
Solar-Powered Pump Installation
Selection and installation of a DC or AC solar submersible or surface pump, hydraulically sized to the borehole yield, total dynamic head, and daily water demand. Rising main, borehole head assembly, safety rope, drop cable, and pump-to-controller wiring — all installed to manufacturer specification.
Solar Panel Array & Controller
Tier-1 solar panels mounted on galvanised ground frames or roof structures at the optimum tilt angle for the site latitude. MPPT pump controller or hybrid inverter configured for dry-run protection, float-switch integration, and optional GSM telemetry. DC cabling in UV-rated conduit throughout.
Water Storage Tanks & Civil Works
Polyethylene, GRP, or steel storage tank design and supply. Elevated tower structure or ground-level platform construction, complete with inlet, outlet, overflow, vent, and drain pipework. Sized for 1–3 days' demand to ensure continuous water supply through low-irradiance periods.
Water Treatment System
Laboratory analysis of the borehole water followed by design and installation of appropriate treatment: sand filtration, UV disinfection, chlorination dosing, reverse osmosis, fluoride removal, or iron & manganese removal — ensuring water meets Kenya's KS EAS 12:2014 drinking water standard.
Distribution Pipework & Taps
uPVC or HDPE distribution mains from storage tank to point-of-use — standpipes, tap stands, or building connection. Stop valves, pressure gauges, and isolation points installed at all major junctions. Can include drip or sprinkler irrigation laterals for agricultural projects.
Solar Power for Buildings (Optional)
Where the project scope includes electricity for a farmhouse, school block, clinic, or operations building, we add a rooftop solar PV system with battery backup — covering lighting, fans, computers, phone charging, small medical equipment, and basic security. Sized and quoted as part of the same project.
How We Deliver a Complete Water-Solar Project
From first enquiry to water flowing and power on — every step is managed by Vajra Drill under a single project contract.
- 1Free Site Assessment & Needs Scoping
Our combined water-and-solar engineer visits the site to assess borehole feasibility (geology, access, nearby water points), measure or estimate daily water demand, evaluate available land or roof area for solar, and confirm the electrical infrastructure to be served. No fee, no obligation.
- 2Geophysical Survey & Solar Irradiance Assessment
VES or ERT geophysical survey identifies the optimal drilling location, estimates depth to water-bearing formation, and predicts sustainable yield. Simultaneously, the solar engineer confirms irradiance, shading, and optimum panel orientation. Both datasets feed into a single integrated design.
- 3Integrated Design & Itemised Quotation
We produce a complete project design covering borehole specification, pump model, solar array size, battery bank (if applicable), tank volume, treatment type, and pipework layout — all as one coordinated document. A detailed BOQ and itemised quotation is provided, suitable for board approval, donor reporting, or bank financing applications.
- 4WRA & REREC Permitting
We prepare and submit the WRA drilling permit, intended abstraction volume, and any required NEMA screening form. REREC solar system pre-registration is handled in parallel. Regulatory timelines are flagged clearly in the project programme so there are no unexpected delays on site.
- 5Drilling, Civil Works & Infrastructure Installation
Drilling rig and installation crews mobilise in one movement. Borehole drilling, casing and development, pump lowering, tank foundation and civil works, solar panel mounting, controller and inverter installation, and distribution pipework are scheduled to run concurrently wherever possible — minimising site time and client disruption.
- 6Water Treatment Installation & Lab Testing
After borehole development, a water sample is sent to an accredited laboratory. Treatment system components are installed and commissioned based on confirmed water quality results. Final post-treatment water samples are tested to verify KS EAS 12:2014 compliance before water is declared fit for use.
- 7Commissioning, Training & Handover
Complete system commissioning test: pump output at design head, solar array IEC 62446 string and insulation tests, treatment system dose rates, and distribution pressure checks. Operators are trained on daily use, routine maintenance, and fault identification. Full as-built drawing set, O&M manual, WRA compliance certificates, and REREC registration documents are issued at handover.

Complete Water-Solar Projects FAQs
A full turnkey project typically includes: hydrogeological survey, borehole drilling, casing and development, pump selection and installation, rising main and borehole head assembly, solar panel array, controller or inverter, storage tank and civil works, water treatment system, distribution pipework, commissioning and testing, WRA abstraction licence, REREC registration, operator training, and handover documentation. The exact scope is agreed at the design stage based on your needs and budget.
For a medium-sized project — borehole, solar pump, 10,000 litre tank, basic treatment, and distribution to a school or small community — total project duration is typically 6–10 weeks from contract signing. This includes 2–3 weeks for WRA permitting (which often runs in parallel with mobilisation), 2–3 days for drilling, 1 week for civil works, and 3–5 days for solar and pump installation. Large or complex projects with extensive pipework may take longer.
All Vajra Drill complete projects are designed to deliver water meeting KS EAS 12:2014 — Kenya's national drinking water quality standard, which is aligned with WHO guidelines. Post-treatment water quality testing is conducted by an accredited laboratory, and a compliance certificate is included in the handover documents. Where water is for livestock or irrigation use only, treatment is designed to appropriate standards for those applications.
Yes, and we commonly structure projects in phases. A common approach is: Phase 1 — borehole drilling and casing only (lowest mobilisation cost); Phase 2 — pump, solar, and basic storage once borehole yield is confirmed; Phase 3 — treatment and distribution network as funds become available. We design Phase 1 with future phases in mind so upgrades are straightforward and no work needs to be redone.
Yes. For NGO, donor-funded, or CSR projects we provide: a full project completion report with photos and GPS coordinates, as-built drawings, laboratory water quality certificates, WRA abstraction licence, REREC registration, population or beneficiary data, and a financial summary in the format required by the sponsoring organisation. We can also provide progress reports during the project and attend donor visits on request.
Our geophysical survey significantly reduces — but cannot eliminate — the risk of a low-yield borehole. If yield is lower than anticipated, we design the pump and storage system to optimise the available yield, which often still meets community needs through larger storage buffer. In the event the yield is genuinely insufficient and an alternative location is indicated, we advise on re-drilling or alternative water sources, including rainwater harvesting integration.
