The department is responsible for environment and water regulation, serving as a ‘one stop shop’ for industry and developers, with the aim of streamlining and simplifying regulation.

Established on 1 July 2017, the department’s functions include science and planning, policy and programs, compliance and enforcement, and regulatory services. The department uses quality science to inform policy, risk assessments, decisions, advice and regulatory activities.

The department provides services to the Environmental Protection Authority, the independent statutory body that conducts environmental impact assessments and develops policies to protect the environment.

The department also supports the Keep Australia Beautiful Council WA, the Waste Authority of Western Australia, the Office of the Appeals Convenor, the Cockburn Sound Management Council and the Contaminated Sites Committee.

Working as a system steward for water and the environment, the department partners with stakeholders from all sectors to sustainably manage the state’s water resources and support a healthy environment.
