HGEC is an Australian consultancy who delivers technical expertise in groundwater engineering, hydrogeology and groundwater modelling

About Us

HGEC — A Legacy of Excellence Since 2002

 

Hydro Geo Environmental Consulting is a scientific consultancy based in Victoria. HGEC provide analytical services and technical advice to a wide range of sectors. Our clients include private, commercial, industrial and government, interested in a variety of activities including research, specialised monitoring and sampling, asset management, risk assessment, geophysical mapping, or geoscience audits.

Our technical backgrounds include geology, hydrogeology, engineering, computer programming (Fortran), GIS analysis and community consultation. We have experience working within government and external for more than 30 years.

We can also bring soil, ecology, geotechnical engineering, agricultural and community consultation services to projects through working relationships we have developed with other specialist independent consultants.

Hydrogeological Investigations​

Experience & Capability

We design and deliver fit-for-purpose hydrogeological investigations that stand up to technical and regulatory scrutiny. Our work spans desktop assessments, targeted drilling, hydraulic testing, monitoring and sampling, with clear, decision-ready reporting for development, infrastructure, mining and environmental projects.​

What we do

We characterise hydrostratigraphy, quantify groundwater occurrence and movement, and translate measurements into practical inputs.

How we work

Programs are planned to answer specific decisions—minimising footprint while maximising confidence and aligning with AS 1726.

Expert Witness Support

HGEC has experience in providing independent technical audits and expert evidence for planning, environmental and civil matters before VCAT, TasCAT and the NSW Civil and Administrative Tribunal (NCAT). Our experts act under the relevant Expert Witness Codes, with opinions that are impartial, transparent and grounded in the Australian Groundwater Modelling Guidelines (AGMG).​

Basement Dewatering & Design

HGEC specialises in defining cost effective design groundwater levels (DGLs) for basements from excavation through operation, so structural, waterproofing and drainage designs are based on defensible hydrogeology.

Groundwater Investigations

Greenfield (exploration and feasibility). We establish the baseline hydrogeological setting, define hydrostratigraphy and recharge–discharge pathways, identify receptors (springs, streams, neighboring users, GDEs), and quantify early inflow ranges to inform pit design and schedule. Preliminary water balances capture runoff, pit catch, seepage and groundwater make, providing inputs to cost, risk and approvals planning.

Screening investigations and conceptual models aligned to approvals needs.
Scoping dewatering concepts (perimeter wells, in-pit sumps/drains) with indicative inflow bands and seasonal variability.
Baseline monitoring network design and approvals pathway mapping.

Groundwater Modelling

HGEC delivers defensible groundwater models from feasibility through approvals. Our practice combines robust conceptualisation, disciplined calibration, and transparent uncertainty analysis so decision-makers can act with confidence.

Groundwater Sampling

HGEC has extensive experience planning and executing groundwater monitoring programs for municipal, industrial and mining clients. Our teams collect defensible, regulator-ready datasets across a wide range of aquifer conditions, bores and access constraints

Hydraulic Parameterisation (Packer Testing & Slug Testing)

We measure how readily groundwater moves to de-risk design, dewatering and contamination projects. Our team applies two complementary field methods for fast, defensible permeability data.
