Project overview The Christies Beach Wastewater Treatment Plant (Plant) receives and treats wastewater from the surrounding communities and industry. Since the Plant was commissioned in the early 1970's the population of the region has increased and is expected to continue to grow over the next 25 years. To meet this expected population growth, SA Water is planning a $272 million upgrade to the Plant. SA Water is working with United Water to deliver the upgrade project. SA Water is responsible for the overall project delivery and United Water, who currently operates the Plant, is responsible for the design and construction management of the upgrade. The project will: increase the capacity of the Plant to meet projected demand to the year 2030 reduce the nutrient load discharged to the marine environment decommission and rehabilitate the Noarlunga Downs sludge lagoons improve the general amenity of the area around the Plant. Construction starts In October 2008, the Development Assessment Commission approved the project, enabling SA Water and United Water to start construction. Tenders are currently being let in anticipation of works beginning in January 2009. The majority of construction work will take place on the Plant site however, there will be some activities that may impact on residents and visitors to the area. These include: increased traffic accessing the site construction of a new pedestrian path along Marine Drive installation of a new outfall pipe local street trenching to install new services implementation of other new recycled water projects.
