ESCPs, flood modelling, mine water balances, soil and erosion assessment - delivered with direct senior involvement. Need the terrain too? FWS also delivers M400 + L3 UAV LiDAR survey and analysis.
Engage FWS for a single plan, model, assessment or UAV LiDAR survey - or combine services when a problem crosses disciplines.

Relevant Project Experience
Goldsim water balances and Water Management Plans for disused and care-and-maintenance metalliferous mines

Flood modelling for mines and infrastructure, catchment hydrology and hydraulic assessment to understand flood behaviour, compare options and inform design. We can capture the LIDAR required for our, or others' flood models in remote areas, reducing model errors and assumptions by collecting the terrain data ourselves rather than relying on third-party or coarse public data.

Understand Erosion Before You Treat It
Work out erosion hotspots across a catchment to target the best value-for-money returns. Use geomorphology, hydraulics and soil evidence to work out why an area is eroding and inform the design brief.

Who We Work With
Mine Environmental Officers
Get water-management answers and ESCPs translated into terms your operations and approvals teams can act on - no hydrology degree required.
Government & Councils
Understand flood and waterway risks and plan environmental works, with documented findings to support design and procurement decisions.
Civil, Infrastructure & Renewables
Get the flood, drainage, soil and erosion inputs your design needs - scoped right the first time, by someone who's sat on the environmental side too.
NRM & Land Managers
Turn a catchment objective into a scoped, engineered response - diagnosis, prioritisation and monitoring, in language your funding body expects.
Environmental & Engineering Consultants
Add senior water, erosion, geomorphology or UAV LiDAR capability to your team, from someone who's worked both sides of the scope.
Site Understanding From the cause of the problem to the practical response
Direct Senior Involvement
Where Environmental Insight Meets Engineering Delivery.
An environmental officer often doesn't know what an engineer needs. An engineer delivers exactly what's scoped, then moves on. FWS works from inside both worlds - so the brief captures the real problem, and the deliverable holds up on both sides.
Bring an existing model, commission a defined study, or have FWS collect the evidence too. The work is scoped to what your team needs to deliver.
A Report Is Part Of The Job. A Usable Answer for On-Ground Action Is The Point.
Recommendations need to make sense on the ground as well as on paper. FWS explains the options, assumptions and limitations so your team can plan works, support an application or decide where to invest next.

Director · Principal Environmental Scientist
Science For Engineers.
Reece Fraser brings 18 years across environmental consulting, engineering and mining - the last 10 inside environmental and water-resource engineering delivery. That's enough time on both sides to know an environmental officer and an engineer can talk past each other on the same problem. FWS closes that gap: turning the environmental question into a scope an engineer can act on, and the engineering deliverable into evidence you can use. You get direct access to that experience, backed by a trusted partner network for additional expertise or certification.
