Sydney’s water and sewerage related infrastructure is set to receive a $755 million upgrade as the government ramps construction efforts across the city’s water network to cater to long term population growth in areas such as the Blue Mountains and Illawarra.
Last week, Finance and Services Minister Greg Pearce announced that 10 contractors had been selected to design and build new water and wastewater systems.
The chosen contractors include a joint venture between Balfour Beatty and Leed, Comdain Infrastructure, Diona, Interflow, ITS Trenchless, Kembla Watertech, Metropolitan Restorations, Veolia Water Network Services, Water Infrastructure Group and the Zinfra Group.
Pearce says the works are aimed at catering to expanding population in some areas and will help support housing and economic development.
“Sydney, the Blue Mountains and the Illawarra have a growing population and with that comes the need for efficient water and wastewater services in existing and developing suburbs and for business,” Pearce says.
He added that works would include water main renewal and sewer upgrades and that the selection of contractors follows the appointment last year of a program management advisor, management team and four renewal delivery contractors to deliver $1.3 billion in new water infrastructure investment.
Pearce says the aforementioned contractors will form panels that will bid for various work packages involving different categories of pipe laying and refurbishment work.
He says the service providers would work in partnership with Sydney Water to deliver infrastructure over the next five years.
The latest developments follow recent controversy amid state opposition claims Sydney would lose more than 40 billion litres of water this year due to leaky and broken pipes.
Sydney Water has defended its record, however, saying it had achieved the highest possible rating for water utilities under World Bank guidelines for leak reductions and will invest more than $350 million upgrading and renewing water mains and pipelines over the next four years.
