Services
Seven capabilities, one technical contract.
Every stage of a water-infrastructure project — from siting the well to billing the meter — handled in-house by a single accountable engineering team.
Why it matters
End-to-end delivery, in-house.
When each stage of a water project is contracted separately — survey to one firm, drilling to another, equipping to a third — accountability gaps form between stages. If the borehole underperforms, each contractor points at the previous one.
Gemrigs closes those gaps. The geologist who produces the siting report also reviews the casing schedule. The engineer who designs the storage tank also signs off the reticulation pressure test. One firm, one contract, one technical chain of responsibility.

A seven-step engineering lifecycle.
Each service is a stage in the same disciplined sequence — and we are accountable for every stage we touch.
- 01
Surveying
Hydrogeological assessment, VES (Vertical Electrical Sounding) and resistivity mapping, and precise siting reports.
- 02
Permitting
Comprehensive WRA, NEMA, NCA, county, and EPRA regulatory approvals managed entirely end-to-end.
- 03
Drilling
High-capacity DTH (Down-the-Hole) pneumatic drilling with continuous 2-meter lithological sampling.
- 04
Testing
Step-drawdown and 24-hour constant-rate pumping tests paired with certified water quality laboratory analysis.
- 05
Equipping
Custom-engineered stainless-steel submersible or solar pumping systems, precisely sized to the borehole's safe yield.
- 06
Staging & Storage
Tower and tank fabrication built strictly to Eurocode 2 and BS 8007 liquid-retaining structures standards.
- 07
Maintaining
Scheduled preventive inspections (bi-weekly to annual) and complete borehole rehabilitation when required.
