Slurry & Mechanical Engineering

ATC Williams’ Slurry and Mechanical Engineering Group provides leading design and project optimisation services for tailings handling and dewatering, slurry and mine water transportation systems.

Our team is staffed by experienced engineers, specialising in the process, hydraulics, and mechanical design fields. This expertise is uniquely supported by the ATC Williams laboratory, with specialist testing methods for slurry and water flow characterisation.

— Our Expertise

Safety and efficiency form a nexus within the slurry and mechanical engineering process. Our practice works across the range of tailings containment solutions, seeking to achieve fit-for-purpose outcomes. Advocacy for thickened tailings solutions, where deemed appropriate, creates opportunity to improve containment reliability, storage efficiency and environmental upside through water conservation.


Based in our Melbourne Office, the Slurry and Mechanical Engineering Group offers a full engineering service for tailings slurry and mine water handling systems including:

  • Options assessment, design and optimisation of tailings handling dewatering, transportation, and distribution systems
  • Unthickened, thickened, and filtered tailings mechanical infrastructure
  • Pipeline and open channel design
  • Process control system design
  • Capital and operational costing
  • Equipment selection and procurement
  • Construction and commissioning


ATC Williams’ offering is highlighted by the integration of skills across the range of service areas, reflecting values that centre on cost efficiency, safety, and environmental performance.

These values recognise that:
  • Slurry engineering is an integral part of tailings management and water management systems throughout the life of any mining project 
  • Troubleshooting of tailings management systems is a speciality, from the perspective of slurry delivery as well as post-deposition
  • As the use of dewatered tailings continues to improve safety for containment and water conservation, we take a holistic view in developing the most suitable arrangement for tailings management 
  • System performance is fundamental to our involvement; tailings/slurry behaviour aligned to overall water balance and water supply demands are significant to risk profiling and costs to optimise performance outcomes
  • The Slurry and Mechanical Engineering Group specialises in the planning, design, and implementation of thickened tailings discharge, filtration, and dry-stack (filtered tailings) systems, offering cost savings and lower risk profile 
  • ATC Williams fund research specific to tailings (slurry) and its associated aspects, enabling all client projects to benefit from evolving engineering methods 
  • Our approach targets water conservation, containment efficiencies and improved safety

— Partnership Focused

Strong partnerships with our mining clients around the world are built on our clear understanding of needs developed through years of experience and investment into knowledge.
