The Department of Defence identified areas of infrastructure critical to Base operations which where not performing adequately and required upgrades to meet current and future operational needs. These included storm water infrastructure, potable water mains infrastructure and sewage infrastructure. Works were delivered in various areas of the operational Base which includes a live civilian and military operating runway and terminal facilities.

A significant portion of the works included the installation of a new Waste Water Treatment Plant to service the entire Base, where previously there were no such facilities. This included a fully automated treatment system with irrigation areas for treated wastewater. This was carried out successfully including its installation to a location that was in the approach path for landing and taking off aircraft.

The project involved 100% engagement of Western Australian contractors, with the engagement of over 70% of the works to local Learmonth/Exmouth contractors, employees and suppliers.

Innovation on this project included solutions to limit damage to existing significant potable water infrastructure. This involved a proposal to relocate the installation of a new potable water main adjacent to the existing one. The current water mains was a 60-year-old asbestos water mains that was fragile and assumed not to be in good condition. The project team suggested relocation of the installation of the new water mains away from the existing mains to avoid any vibrations or cause to fracture the delicate existing mains. This was delivered successfully with no damage resulting and no additional cost to the Commonwealth.
