Water Resource Management & Modelling

Site water balances and resource models that carry real decisions (licence applications, storage sizing, discharge strategy), built from catchment behaviour rather than assumed factors.

  • Water and salt balance modelling for resource management
  • Hydrological modelling of catchment runoff and rainfall response
  • Groundwater flow and contaminant transport modelling
  • Groundwater baseline studies for new and expanding operations
  • Surface water contaminant transport modelling
  • Water quality modelling for resource and compliance decisions
  • Water quality monitoring programme design and data interpretation
  • Storage, containment and discharge strategy assessment
  • Seasonal and sub-seasonal forecasting for improved water security

Mine Water & Acid Mine Drainage

Acid mine drainage is a chemistry problem with a fifty-year tail. We predict where it will occur, characterise what it produces, and design treatment that still works after the mine has closed.

  • AMD prediction and geochemical characterization
  • Water chemistry and management in mining environments
  • Mine water treatment and remediation technology selection
  • Active mine water treatment system design
  • Passive treatment design for post-closure liability
  • Mine water reclamation, management and reuse strategy
  • Closure and long-term liability assessment

Wastewater & Water Treatment Engineering

Design, modelling, optimization and upgrades across municipal and industrial treatment, including the effluent streams that no off-the-shelf plant will accept.

  • Industrial wastewater treatment plant modelling and optimization, across mining, agricultural and industrial streams
  • Domestic and municipal wastewater and sewage treatment design
  • Potable and process water treatment design
  • Water reuse and reclamation technology selection and design
  • Plant upgrades, capacity reviews and refurbishment scoping
  • Discharge compliance and limit-of-performance assessment

Process Modelling, Optimization & Simulation

A calibrated process model answers the question capital cannot afford to answer by trial: what will actually happen if we change this? We build mechanistic models and test the options in software first.

  • Mechanistic and kinetic process modelling, including activated sludge models
  • Biological nutrient removal modelling and troubleshooting
  • Process optimization and debottlenecking
  • Scenario testing and what-if analysis ahead of capital commitment
  • Site-specific and emerging contaminant fate and behaviour studies

Automation, SCADA & Digital Twins

Control systems specified by the engineers who modelled the process, so the loops match the chemistry, with digital twins for testing operating strategy without risking the real plant.

  • Control systems engineering and design
  • SCADA and PLC system specification and implementation
  • Instrumentation selection and control philosophy development
  • Digital twins of treatment and process plants
  • Manufacturing and packaging line logic design
  • Custom scenario-testing software for operations teams

Technical Advisory

Independent technical judgement for boards, regulators, lenders and legal teams, including reviewing work produced by other engineers.

  • Feasibility studies, technical reports and proposals
  • Regulatory and permitting support
  • Water reuse governance and institutional arrangements
  • Independent technical review and second opinions
  • Due diligence support on technical assets
  • Expert input for technical disputes and compliance matters
