Seqwater is a statutory authority of the Government of Queensland that provides bulk water storage, transport and treatment, water grid management and planning, catchment management and flood mitigation services to the South East Queensland region of Australia.

Since that time Seqwater has retained its bulk water storage and treatment, catchment management and flood mitigation assets and functions while acquiring additional assets and functions in two tranches: Seqwater is managed by a chief executive who reports to a Board of Management that are ultimately responsible to the Minister for Regional Development and Manufacturing, and Minister for Water, presently Glenn Butcher and the Queensland Treasurer and Minister for Trade and Investment, presently Cameron Dick.

[3] The formation of Seqwater was part of the reform of water supply arrangements by the Queensland Government that commenced in 2007.

As part of these reforms an integrated approach to catchment-sourced management across the South East Queensland region was adopted with the expectation that this approach would help to ensure the long term security and sustainability of the region's catchment-based water supply.

In addition, Seqwater owns 47 weirs, as well as operating 46 water treatment plant facilities and 14 groundwater borefields across South East Queensland.
