The SEQ Water Grid is a region-wide, long term, water supply scheme that provides a sustainable water infrastructure network for the South East region of Queensland, Australia. The project was the largest urban response to the drought in Australia, which severely affected water supplies in Brisbane and surrounds, particularly between 2004 and 2007. The basic component of the project was a 535-kilometre (332 mi) network of potable bulk water pipelines that connect areas that have an oversupply of water to those areas lacking water.[1] The project went online in October 2008 and by November 2008 parts of the region were receiving a diversified supply of water for the first time.[2]

Features and structure

The SEQ Water Grid was initially managed by a partnership between

state-owned corporation that owns and operates the SEQ Bulk Water Supply System or the Bulk Water Supply Chain.[4]

The plan for the Water Grid was originally laid out in the

water restrictions on residents. Other aims of the Water Grid are to move risk away from individual water storage facilities to the regional level and to efficiently coordinate the utility of water sources in South East Queensland.[5][6]

Components

Existing facilities that have become part of the Water Grid include

sea water to drinking water and the Western Corridor Recycled Water Scheme
to purify treated wastewater for supply to power stations and industrial and agricultural customers. Purified recycled water will also be added to the water supply once combined dam levels fall below 40 per cent.

Two major pipelines, called the Northern and Southern Pipeline Interconnectors, link water storage facilities near Gympie in the north of the region and the Gold Coast area, south of Brisbane. Wyaralong Dam and the completed Cedar Grove Weir are part of the plans. These water reservoirs provide significant new supply and are needed to meet the region's growing demand up until 2050.[7] In 2008 Lake Manchester Dam and Enoggera Dam were reactivated to supplement supply.[7] The project also encompasses a raising of the Hinze Dam dam wall and the connection of the Leslie Harrison Dam and Ewen Maddock Dam to the regional network.
