This position is responsible for monitoring and managing the groundwater, surface water removal and Tailing Storage Facility (TSF) for the Motheo Mine Site.

The role is responsible for managing the sitewide water balance including dewatering activities, plant water supply, managed aquifer recharge and technical aspect and comprehensive monitoring system of TSF.

Key Performance Areas

  • Applies basic knowledge of water rights and legal issues to the management of the site wide water balance.  Participates in water stewardship committee, other stakeholder groups and public agency meetings as the subject matter expert.
  • Management and optimization of the long-term pit dewatering strategy, including dewatering pumping systems, efficiencies, and related piping infrastructure.
  • Develop and maintain engineering drawings packages for pipeline system.
  • Perform hydrological assessments and oversees ground water and surface water investigations for the operation.  Work includes research, compilation, and interpretation of complex hydrological data include groundwater modelling.
  • Support development and implementation of slope depressurization strategy.
  • Manage and improve ground water monitoring strategy, test results and monitoring data of properties of bodies of water including volume, stream flow and potential pollutant.
  • Oversee piezometer, well boreholes drilling, hydraulic testing and installation of groundwater monitoring instrumentation.
  • Provide hydraulic parameters and water level data for refinement of pore pressure models for geotechnical analysis.
  • Review dewatering extraction models and recommend necessary model changes/updates.
  • Perform TSF slope inspections and document seepage locations.
  • Manage data management for TSF integrated monitoring system (rainfall, piezometer, survey of bathymetric single/multiple beams, drone, Global Navigation Satellite System-GNSS and Real Time Kinematic -RTK.
  • Oversee the design, construction, modification, expansion, operation, and maintenance of robust TSF system.
  • Develop long-range tailings depositional plans, considering safety, environmental impact, and efficiency.
  • Ensure the quality and compliance of daily inspection and monthly TSF reporting.
  • Oversee special projects, including pump optimization, managed aquifer recharge, and surface water management/distribution systems.
  • Manage consultants and contractors and perform technical reviews.

Technical Competencies

  • Knowledge of groundwater flow in fractured-controlled hydrogeological conditions.
  • Knowledge of the principles and methods used in complex hydrogeological analysis, including groundwater modelling, production borehole siting, design, installation, and pumping system optimization.
