Here you'll find the latest information about our work health and safety requirements.

Work Health and Safety policy

Our Work Health and Safety (WHS) policy outlines our commitment to providing and maintaining best practice health and safety at workplaces under our control.

Safety essentials

Safety essentials provide guidance on what must be in place and the checks that must be done before commencing high risk activities. Our safety essentials are non-negotiable as nothing is more important to us than the safety of our people, contractors and community.


  • The Leader's Guide outlines the mandatory system requirements that must be in place to support the management of high risk activities.
  • The Field Guide is a tool for field workers to check mandatory requirements are in place. Note: The Field Guide is not mandatory for contractors, however the link is provided as an option to assist those in the field.

Health safety & environment requirements for contractors

The Health Safety and Environment Requirements for contractors outlines our procedures and general requirements for contractors working with us.

Water Corporation’s priority is to:

  • protect the health and safety of our people, including our contractors and the community in which we work
  • have systems and processes that enable business continuity and the ongoing provision of critical services to Western Australia.
