The Department of Energy and Water Supply and the Department of Natural Resources and Mines have been combined to create the new Department of Natural Resources, Mines and Energy.

We will continue to update this website while we work on our new website.

Department of Natural Resources, Mines and Energy

Bulk water entities

Responsibility for water is spread across a number of government agencies:

  • DEWS has a governance, regulatory and oversight role for a number of state-owned water entities (commercial businesses) providing water supply services.  
  • DNRM is responsible for management of the state's natural resources, such as water management and planning.  
  • DEHP is responsible for the monitoring and protection of water environments.  
  • DAF is responsible for managing water resources for irrigation.  
  • Queensland Health co-regulates water quality with DEWS to assure safe drinking water.  
  • DILGP is responsible for planning that enables responsible development and protection of natural resources.  

The Queensland Government has responsibility for a number of water entities which provide services to the community which are essential – including critical water supply infrastructure, such as dams and water treatment plants, and services to support consumer needs.

Water entities in Queensland include:

  • Government owned corporations  
  • Category 1 and Category 2 water authorities (Category 2 water authorities are smaller than Category 1 authorities and are overseen by DNRM)  
  • Statutory authorities.  

Water providers in Queensland also include:

  • local governments  
  • private providers.
