The desalination plant – comprising 29 buildings including the reverse osmosis building, the heart of the VDP - with a production capacity of 150 billion litres of water a year, flexible water ordering of between 0 and 150 billion litres, and the capability to expand to 200 billion litres a year
Marine structures: two underground tunnels located 15 metres below the seabed measuring 1.2 km and 1.5 km long and each with a 4 metre internal diameter, and associated marine intake and outlet structures located more than 20 metres below the sea’s surface
Water transfer pipeline: 84 km, 1.9 metre diameter, two-way pipeline that provides desalinated water or catchment supplies to communities throughout Melbourne, South Gippsland and Westernport, as required;
The plant’s design aims to minimise any adverse impacts on landscape, cultural heritage, fauna and flora, or local communities.
Its land-based components are integrated into the landscape, thereby reducing the amount of energy needed to lift the seawater to the plant. The highest point of the main buildings is 20 metres above sea level, barely visible from surrounding areas.
