Private well drilling
Exploration discipline before the rig ever mobilizes.
Dry-hole risk is real on private parcels. WRI starts with hydrogeologic assessment and site evaluation, coordinates county well permits and DOH requirements, then mobilizes certified drillers with the depth capability to complete production wells across Hawaii formations.
What we deliver
Scope built for your property
-
Groundwater exploration
Hydrogeologic review, existing records research, and site evaluation to reduce dry-hole risk before mobilization costs begin.
-
County permit coordination
Well permits, DOH requirements, and documentation managed through drilling and commissioning — not left for the landowner to navigate alone.
-
Deep well drilling
Production wells to 2,800 ft with experienced drillers who know Hawaii basalt, alluvial, and coastal recharge formations.
-
Yield & water quality testing
Documented yield testing and sampling so you know production before pump sizing and long-term planning.
-
Pump install & commissioning
Deep well pumping systems installed and commissioned to match verified yield and property demand — drill through startup.
-
Clear project communication
Private landowners get direct timeline and scope communication — what happens before, during, and after the borehole is complete.
How it works
From parcel assessment to production
- 01
Site assessment
Review geology, prior well records, intended water use, and permit requirements for your parcel and county.
- 02
Permit & design
Coordinate county well permits, DOH requirements, and anticipated depth and pump approach with your timeline.
- 03
Drill & test
Mobilize certified drillers, complete the borehole, and run yield and water quality testing before pump commitment.
- 04
Pump install
Install and commission a pumping system matched to verified production and residential or estate demand.
- 05
Document & hand off
As-built documentation, testing records, and operational guidance so your asset is permitted, proven, and maintainable.
Why WRI
Why private landowners choose WRI
-
35+ years in Hawaii
WRI has drilled across the island chain since 1989 — formation knowledge that reduces guesswork on private parcels.
-
Exploration before drilling
We assess before we mobilize. Private owners deserve the same pre-drill discipline that government contracts require.
-
Full-scope capability
Exploration, drilling, testing, and pump install under one firm — no handoff gaps between the bit coming out and water reaching your home.
-
Contract-proven crews
The same licensed drillers who complete $150M+ in public work mobilize for private residential and estate projects.
Private parcels, professional standards
Residential wells drilled with the same discipline as public contracts.
A private well is a long-term asset. WRI brings exploration methodology, deep drilling capability, and pump expertise to homes, estates, and agricultural parcels — with permits and testing handled through completion.
- Production wells to 2,800 ft for demanding Hawaii geology
- Honolulu headquarters and Kawaihae field office mobilization
- Residential, estate, and agricultural private water supply
- Exploration-first approach to protect against dry-hole cost
- Pump commissioning matched to verified yield — not assumed flow
Common questions
What clients ask us
How deep can WRI drill on a private residential parcel?
WRI has drilled production wells to 2,800 ft in Hawaii formations. Actual depth depends on geology, aquifer target, and permit conditions for your specific parcel.
Does WRI handle county well permits?
Yes. WRI coordinates county well permits and DOH requirements as part of the project scope — private landowners are not left to navigate permitting alone.
What if exploration suggests a poor site?
That is exactly why assessment comes first. WRI evaluates geology and existing records before mobilizing so private owners understand risk, alternatives, and next steps before major drilling cost.
Can WRI drill and install the pump?
Yes. WRI develops wells from exploration through pump commissioning — one firm accountable from first assessment to water at the property.
