It's official, the Barangaroo precinct has its own ecosystem.
Lendlease has completed one of the major pieces of infrastructure at its $6 billion Barangaroo site with the opening of its recycled water plant.
The plant has a projected production of more than 200 million litres annually and will make the precinct one of the most sustainable in the country.
According to Lendlease, the plant is a critical and final piece of Barangaroo's infrastructure network to make the precinct water positive, meaning Barangaroo will be capable of producing more water than it consumes and will become a net exporter of recycled water.
The NSW minister for energy and utilities Don Harwin, who was at the opening on Friday, said Barangaroo a was an ''example to the rest of the world of what partnerships between government and the private sector can achieve''.
"Lendlease has set a new precedent for water conservation in an urban area creating a positive and lasting legacy for both Barangaroo and the wider central business district," Mr Harwin said.
"This is a critical step to fulfil our ambition to make Barangaroo one of the world's most sustainable urban regeneration precincts.''
When completed, Barangaroo will be home to three nearly fully occupied office towers, a new retail area on the central site and close to 1000 apartments.
Currently about 25,000 workers and visitors arrive in the area daily from the new link to Wynyard station and the regenerated pedestrian strip along George Street.
The integrated energy company, Origin, is the latest tenant to Barangaroo, having signed an agreement to lease 7,850sqm in the building, for a 10-year period with a further two five year options.
Origin will consolidate its two Sydney offices, currently located at Australia Square and Bond Street, into its new home at Barangaroo by mid-2018.
Mr Harwin said there were now 20 private recycling schemes licensed under the Water Industry Competition Act.
Lendlease Property Australia chief executive Kylie Rampa said integrating the plant with Barangaroo's low carbon, waste management and renewable energy strategy was the culmination of ''seven years' work''.
''The opening of the Barangaroo South Recycled Water Plant represents a final piece of the puzzle towards us becoming Australia's first water positive precinct,'' Ms Rampa said.
''Barangaroo's other infrastructure network also includes the district cooling plant, which uses Sydney Harbour water to cool all the precinct buildings, 188,500 litres of water across the area, 6,000 sqm of roof-top solar panels and a private power network.
Aside from its office and residential towers, Lendlease has also built a timber property using cross laminated timber (CLT) and glue laminated timber (glulam).
Known as International House Sydney, it will be the new home of Accenture and will help Barangaroo to become the country's first large scale carbon neutral community.
