Water Infrastructure Engineering · Kenya
Engineered water,
delivered to depth.
Hydrogeological surveys, borehole drilling, pumping and storage — with a 98% borehole strike rate, built for a 30-to-50 year operating life, and aligned with Kenya Vision 2030.
Who we are
A professional engineering team for water and civil infrastructure.
By bringing together specialized borehole drilling and civil engineering under one roof, Gemrigs handles the entire lifecycle of your water project under a single contract. Surveying, permitting, drilling, equipping, storing, distributing, and maintaining — everything is done in-house and signed off by WRA-licensed geologists and NCA-registered contractors.
Our work is fully compliant with Kenya's regulatory frameworks — the Water Act 2016, EMCA, NCA Act 2011, the Energy Act 2019, and Building Code CAP 242 — and built to international standards, including Eurocode 2 for liquid-retaining structures.
Read about our approachOne contract. Zero hand-offs.
When each stage of a water project is contracted separately, accountability gaps form. We close those gaps.
No subcontracting
Every stage — survey, permit, drill, equip, store, distribute — is executed by Gemrigs' own engineers and registered contractors. One accountable team throughout.
Licensed for every stage
WRA-licensed geologists, NCA-registered contractors and EPRA-certified solar engineers on every project — the credentials are real and site-active.
Permits managed end-to-end
WRA, NEMA, County, EPRA and NCA approvals filed and tracked in-house. You make engineering decisions; we manage the regulatory process.
Seven capabilities, one technical contract.
From siting the well to billing the meter — every stage of a water-infrastructure project handled in-house.
Hydrogeological Surveys
Science-led siting that de-risks every borehole before mobilisation.

Questions about water engineering in Kenya.
- What services does Gemrigs offer?
- Gemrigs provides seven integrated water engineering services: hydrogeological surveys, borehole drilling, pumping systems installation, water storage construction, modern irrigation, civil works and plumbing, and scheduled maintenance — all delivered under a single technical contract.
- Where does Gemrigs operate in Kenya?
- Gemrigs operates across all 47 counties in Kenya, with a completed portfolio of over 1,500 water infrastructure projects spanning diverse geological terrains from the Rift Valley to the Lake Basin.
- What permits are required for borehole drilling in Kenya?
- Borehole drilling in Kenya requires a Water Resources Authority (WRA) drilling permit, NEMA environmental clearance, NCA contractor site registration, and county government approval. Gemrigs manages all permit submissions end-to-end.
- How long does a borehole project take from survey to commissioning?
- A typical borehole project — from hydrogeological survey to a commissioned pumping system — takes 6 to 12 weeks, depending on permit timelines and geological site conditions.
- What is Gemrigs' borehole strike rate?
- Gemrigs achieves a 98% borehole strike rate, meaning 98 out of every 100 boreholes drilled reach a productive aquifer. This is achieved through comprehensive geophysical surveys — VES and resistivity mapping — before any drilling begins.
- Is Gemrigs licensed and compliant with Kenyan law?
- Yes. Gemrigs employs WRA-licensed geologists, NCA-registered site managers, and EPRA-certified solar engineers. All projects comply with the Water Act 2016, EMCA, NCA Act 2011, Energy Act 2019, and Building Code CAP 242.
