Water supply

Seqwater manages up to $11 billion of bulk water supply infrastructure - including the SEQ Water Grid - and the natural catchments of the region’s water supply sources to ensure a reliable, quality drinking water supply for more than three million consumers across South East Queensland.

These water supply assets include 73,000+ hectares of catchment land, dams and weirs, conventional water treatment plants and climate resilient sources of water through the Gold Coast Desalination Plant and the Western Corridor Recycled Water Scheme, as well reservoirs, pump stations and more than 600 kilometres of bi-directional pipeline network.

We also supply drinking water to 53,000 people living in 16 off-grid communities. The water for these communities is sourced and treated locally, then distributed to households and businesses.

Planning and demand management

Seqwater undertakes long term demand modelling which allows us to manage supply more efficiently, as well as enact water conservation measures and drought response plans when needed. 

On 24 March 2017, Seqwater released version 2 of Water for life - our 30-year plan for providing safe, reliable and affordable drinking water for South East Queensland. This long-term plan will provide enough water to sustain household and business needs for our growing region.
