CreekConnect – Supporting Western Sydney’s Growth!

Be part of a large-scale, long-term joint venture between Seymour Whyte and Jacobs, awarded by Sydney Water as an Engineering, Procurement, and Construction Management (EPCM) project.

The Upper South Creek Network will feature new wastewater pumping stations and gravity carriers, with the first work stage beginning before the year's end. The project also emphasises safety, digital engineering, and compliance with the latest standards, ensuring it meets future needs effectively.
