Posted by waterweek on 17 September 2007

Kay Maywald, Minister for Water Security, told the House of Assembly, South Australia, 11 September 2007 listed South Australian government projects managed through the water security task force:

• disconnection of selected wetlands to yield over 30 gigalitres in water savings;

• modification of the major pumping stations below lock 1 to enable them to operate at the river levels as the river level falls, and to delay as long as possible the need to construct a temporary weir, if at all;

• preparations to construct a temporary weir below the Wellington have been necessary, and they include the design, construction, scheduling and environmental assessment necessary for the project should it need to go ahead;

• pumping of additional River Murray water into storages during the of 2006-07 water year has been essential, and this did increase water storage at the beginning of this year as well as provide a buffer for this year in the event of algal outbreaks in the River Murray and also other water quality issues;

• fast tracked water filtration facilities for 17 communities that presently receive unfiltered water from the River Murray at a cost of in excess of $50 million. This is an important project as we have to deal with serious water quality issues in the future, and providing that filtered water is essential;

• pipeline constructed to supply water to the Clayton community around Lake Alexandrina, which currently accesses its water from the lake; and

• standpipes for water carting have been installed at Goolwa North, Milang, Meningie, Hindmarsh Island and Narrung. “We have streamlined dredging processes to enable irrigators to access water as the river levels below lock 1 have receded”.
