FSG provides specialist hydrogeological and dewatering expertise for civil, infrastructure and land development projects.
We lead groundwater assessments from investigation through to design and regulatory approval, delivering robust, construction-ready outcomes. Our capability spans hydrogeological investigations, design groundwater level (DGWL) assessments, dewatering system design, and advanced numerical modelling. We combine technical depth with practical delivery to manage groundwater risks in complex ground conditions.
A key strength of our approach is the integration of hydrogeological and geotechnical expertise throughout the planning, investigation and design process. By considering groundwater behaviour and geotechnical conditions together, we deliver more robust, efficient and cost-effective outcomes that improve project certainty and support successful construction.
Assessing groundwater conditions.
We scope and deliver hydrogeological investigations to characterise groundwater regimes and inform design. This includes DGWL assessments, groundwater modelling (2D seepage and 3D numerical groundwater models), infiltration testing, aquifer testing, and water balance studies. Our experience spans infrastructure, road construction, land development, stormwater systems, and sub-soil drains, providing clear insight into aquifer behaviour, recharge dynamics, and potential construction risks and impacts.
Dewatering design and management.
We deliver dewatering design and technical support across major infrastructure and civil projects. Our services include system design, performance assessment, end-to-end groundwater related and dewatering construction support and optimisation. We prepare hydrogeological and Dewatering Management Plans to support licensing and approvals, and work closely with regulators. Our team also provides expert advice and evidence in groundwater-related matters, delivering clear, robust outcomes where scrutiny is high.
