This $100 million urban 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.

MDBE has been responsibile for 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 required the design and construction of the entire transfer pipeline system, including over 12 km of 1.6 m-diameter mains pipes, a 300 ML/day transfer pump station and a 9 ML 44m-diameter and 6m-high break pressure tank.

Constructed in a mainly urban environment, the project required meticulous planning and liaison with local authorities and communities. Traffic planning and management was critical, as much of the route follows Lonsdale Road, a high-traffic dual carriageway that links Adelaide’s southern coastal suburbs.
