Geotechnical & Environmental Monitoring

Capabilities

Specialised Monitoring Services​

Egan Drilling provides specialised groundwater monitoring and instrumentation installation services, supporting mining, environmental, and civil projects across Perth and regional Western Australia.
While our core expertise lies in water bore drilling, dewatering, and hydrogeological investigations, we also deliver high-quality geotechnical monitoring bore and instrumentation installations as part of broader groundwater and site management programs.
Our environmental monitoring services are most commonly integrated with water supply, dewatering, and hydrogeological drilling projects - ensuring clients receive accurate data alongside practical, real-world groundwater solutions.
Accurate monitoring data plays a critical role in managing groundwater behaviour, reducing project risk, ensuring compliance, and avoiding costly delays across mining and civil operations.

Groundwater Monitoring Bore Installation in Perth & WA

Our team installs groundwater monitoring bores to support aquifer analysis, dewatering performance, and long-term groundwater management.
These bores are often installed alongside production and exploration water bores, allowing clients to better understand groundwater systems and optimise water extraction or dewatering strategies.
Each bore is drilled to the required depth and diameter for your project, ensuring precise and reliable data collection across a wide range of geological conditions.

Environmental & Groundwater Monitoring Bores

Egan Drilling installs monitoring bores for contamination assessment, groundwater quality monitoring, and regulatory compliance, including DWER requirements.
We frequently deliver these installations as part of integrated groundwater projects, combining monitoring bores with water bore drilling and dewatering systems to provide a complete solution.
This approach ensures monitoring data is directly aligned with site-specific groundwater conditions and operational requirements.

Piezometer Installation for Groundwater Monitoring

We install piezometers to monitor groundwater levels and pore pressure across a range of subsurface conditions.
These installations are commonly used in aquifers, tailings storage facilities, dewatering systems, and groundwater investigations, providing critical data for groundwater management, site stability, and water resource projects.

Vibrating Wire Piezometer (VWP) Installation

Our team installs Vibrating Wire Piezometers (VWPs) for highly accurate, real-time groundwater pressure monitoring.
VWPs are particularly suited to mine dewatering programs, tailings storage facilities, dam embankments, and infrastructure projects where continuous, reliable groundwater data is essential.

50+ YearS Of Experience

Trusted by clients across WA since 1968, with deep knowledge of local geology and drilling conditions.

Custom-Built & Designed Rigs

Our Australian designed and built rigs are purpose-built to handle WA’s unique terrain efficiently and safely.

Family-Owned & Operated

Third-generation business built on integrity, long-term relationships, and hands-on service.

Strict Safety & Reliability

We maintain strict safety standards and deliver reliable results, no matter how remote or complex the site.

Experience

Comprehensive Drilling Techniques

We apply a range of drilling methods across monitoring, hydrogeological, water bore, and dewatering projects, selecting the most suitable technique based on ground conditions and installation requirements.

Mud Rotary

Our mud rotary drilling capability allows us to drill accurately through a wide range of geological formations, making it well-suited to groundwater and monitoring bore installations in variable or unconsolidated conditions.

Down Hole Hammer / Air Percussion

For hard rock environments, our downhole hammer method provides the penetration required for deeper monitoring bores, particularly in mining and dewatering applications.

Multipurpose Drilling Methods

Our rigs are highly adaptable, allowing us to switch between methodologies based on ground conditions encountered on site. This flexibility ensures seamless delivery across both water bore and monitoring programs.

Why Choose Egan Drilling

End-to-End Monitoring Solutions

Our services are tailored to each project, ensuring accurate data collection and dependable long-term performance.

Efficient and Reliable

We work closely with consultants and project managers to deliver efficient, well-coordinated installations with minimal disruption to site operations.

Compliance

As a specialist drilling contractor working across groundwater, monitoring, and environmental projects, we ensure every installation meets Australian industry standards and regulatory requirements.

Safety First

Safety is our top priority. We operate with strict adherence to safety protocols to safeguard our team, your project, and the environment.

WA Coverage & Rapid Mobilisation

We service Perth and regional Western Australia, with the capability to mobilise quickly to remote and demanding project locations.

Complete Groundwater Solutions

Monitoring and instrumentation installation is not a standalone service for us. It forms part of a broader groundwater-focused approach.

Egan Drilling specialises in:

By combining geotechnical & environmental monitoring with these core services, we provide clients with a more complete understanding of groundwater systems to improve decision-making, efficiency, and long-term performance.

Working with a single contractor also reduces coordination issues, improves communication, and keeps projects running smoothly.

Geotechnical Drilling FAQs

What is geotechnical drilling used for?
Geotechnical drilling is used to investigate subsurface conditions and install monitoring instruments. At Egan Drilling, these services are often delivered alongside groundwater, water bore, and dewatering projects.
Geotechnical monitoring bores assess ground conditions and groundwater pressure, while environmental monitoring bores track groundwater quality and contamination for compliance and reporting purposes.
We install vibrating wire piezometers (VWP), standard piezometers, and inclinometer casings, typically as part of broader groundwater or dewatering projects.

Egan Drilling works with clients across mining, environmental consultancy, civil construction, and water resource sectors throughout Western Australia.

Project duration depends on scope, ground conditions, and installation requirements. Our team works efficiently while maintaining strict quality and safety standards.
