More reuse of treated wastewater from the Glenelg Wastewater Treatment Plant and harvesed stormwater, in South Australian project

Posted by waterweek on 21 September 2007

Various different groups in his electorate were looking at a project that involved extending the reuse of treated wastewater from the Glenelg Wastewater Treatment Plant and harvesting stormwater from within the area bounded approximately by the Glenelg Wastewater Treatment Plant catchment, said Labor MP Steve Georganas in the Federal House of Representatives on 14 August 2007.

Annual harvest of five gigalitres: “The reused water from the Glenelg Wastewater Treatment Plant and the stormwater would then be available for irrigation at an alternative location,” Georganas said. “Glenelg and the Adelaide Parklands were found to be the most concentrated regions for significant reuse potential. The project is set to reuse approximately five gigalitres of water annually. This project has great potential and it attacks the issue of water management directly, by saving water that would otherwise be pumped out into the sea and the Gulf St Vincent.”

Stormwater damages marine environment: “Currently large amounts of the treated effluent from the Glenelg Wastewater Treatment Plant are discharged into the Gulf St Vincent, killing off the seagrass and destroying marine life in our gulf,” said Georganas. “The gulf is adversely impacted on by the 174,000 megalitres annually of nutrient rich stormwater surging down from the Adelaide Hills and over the Adelaide flats into the gulf, carrying all the pollutants that destroy the environment within the gulf. The prevention of run-off from the Adelaide Plains is probably the greatest South Australian environmental challenge facing our coast, the residents of metropolitan Adelaide and our governments in this and the next decade.”

Potential of wetlands should be examined: “The ongoing construction of wetlands in Adelaide’s northern suburbs — adjacent to the Parafield Airport and beyond — and associated aquifer storage and replenishment initiatives, of which there are now about two dozen in the greater Adelaide area, have been encouraging for quite a few years,” Georganas said. “We should take a closer look at this as a substantial element of our future supply of water. In areas other than the northern suburbs there has been substantial energy applied to similar projects, such as within the Patawalonga Catchment at Morphettville, which I have mentioned previously.”
