The Christies Beach Waste Water Treatment Plant<\/strong><\/p>\n<\/div>

<\/div>

Commissioned in the early 1970s, the Christies Beach Waste Water Treatment Plant receives and treats wastewater from surrounding communities and businesses.<\/strong><\/p>\n<\/div>

Located in Adelaide\u2019s southern suburbs, SA Water upgraded the Plant to increase capacity and meet the expected growth of the area.<\/span><\/p>\n

Part of the overall Plant upgrade was the construction of a new outfall to discharge excess treated effuent in line with new environmental protection guidelines. The new 1,200mm diameter outfall pipeline was partially buried on the sea floor and extends some 650m from the shore into the Gulf of St Vincent.<\/span><\/p>\n

Reflecting best practice construction, the delivery of the offshore pipe was executed through a combination of innovative approaches including a pipe launch methodology that involved a 180 metre temporary bridge, a sheetpile cofferdam installed through the beach crossing, and a shore-based winch pulling via an offshore anchor.<\/span><\/p>\n<\/div>

The 305m long, 12m wide bridge consists of a post-tensioned concrete box girder, erected by the balanced cantilever method using match-cast segments.\u00a0<\/span><\/p>\n
