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. Seqwater also provides irrigation services to about 1,200 rural customers in the region that are not connected to the grid and provides recreation facilities. Seqwater was established on pursuant to the alongside three other statutory authorities: Linkwater, the SEQ Water Grid Manager and WaterSecure. 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:
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. Initially, Seqwater was established to manage bulk water facilities in the region, a function previously managed by 25 different local government, state government and corporate entities. Seqwater is responsible for 25 dams, which provide as much as 90 per cent of South East Queensland’s drinking 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. Seqwater is also responsible for a range of new water infrastructure projects and initiatives, including raising the dam wall of the Hinze Dam on the Gold Coast, working with the Department of Infrastructure and Planning on the design phase of the Wyaralong Water Treatment Plant, and the fluoridation of the region’s drinking water supply. It currently manages more than $10 billion worth of water supply assets, including 600 kilometres of bulk water pipelines connecting the water grid from the Sunshine Coast in the north to the Gold Coast in the south, the Western Corridor Recycling Scheme and the Gold Coast Desalination Plant. On 6 July 2015 Seqwater released Water for life, a 30 year plan outlining measures to ensure a secure water supply for South East Queensland over the period to 2045.
