The North South Interconnection System Project (NSISP) is one of South Australian Water Corporation’s (SA Water) biggest infrastructure projects in the Adelaide metropolitan area. SA Water built the $403 million project to connect the north and south drinking water distribution systems and to increase access to a desalination plant. The project included the construction of 32 kilometers of pipeline through metropolitan main roads and suburban inner streets. To deliver this project, SA Water assembled an integrated project team comprising staff from a range of private-sector companies. A managing contractor framework was established to deliver the ancillaries program across the entire water network. Several vendors proposed technical solutions to the project’s many phases. Control valves in particular were needed to perform in extreme conditions for several applications. Many hurdles required a long consultation process to define the conditions and brainstorm solutions. In addition, quality, cost, serviceability and accessibility to equipment added more layers to the requirements.
Drops in pressure and shifting flow rates were significant hurdles of a $403 million water project.
