Prospect South to Macarthur (ProMac)

Share on Facebook Share on Twitter Share on Linkedin Email this link

Under the ProMac project we are building new drinking water pipelines and infrastructure between Prospect South and Macarthur as part of Sydney Water's long-term plan to extend the city’s water capacity and supply.

ProMac will upgrade our existing water reservoirs at Liverpool and Cecil Park as well as build two new reservoirs at Oran Park. This will allow for an extra 100 Megalitres of additional reservoir capacity in Western Sydney. That’s the equivalent of about 50 Olympic-sized swimming pools!

We’re also building 15 km of additional pipework, three pumping stations and upgrading our existing network to ensure growing communities in South Western Sydney have access to clean drinking water.

Sydney Water is investing in new infrastructure that will support the growing, dynamic South Western Sydney.

ProMac will help Sydney Water deliver on its vision of creating a better life with world-class water services.
