Due for completion in July 2010, this $100 million water pipeline project is being completed for SA Water by the MDBE engineering company, of which Built Environs is a joint venture partner with McConnell Dowell.

The project involves the construction of a mains water pipeline and associated pumping and other structures to connect the Adelaide Desalination Plant, currently under construction at Port Stanvac, to the existing mains water reservoir at Happy Valley, in Adelaide’s southern suburbs.

The project requires the design and construction of the entire transfer pipeline system, including over 12km of 1.5m-diameter mains pipes, a 300ML/day transfer pump station and a 9ML 44m-diameter and 6m-high break pressure tank.

The pipeline is being constructed in a mainly urban environment, requiring meticulous planning and liaison with local authorities and communities. Traffic planning and management is critical, as much of the route follows Lonsdale Road, a high-traffic dual carriageway that links Adelaide’s southern coastal suburbs.
