(2010 to Present – Logan City Council)
Yarrabilba, a master-planned community located 40 km southeast of Brisbane, is a Priority Development Area managed by Economic Development Queensland. The name “Yarrabilba” means ‘a Place of Song’ in the language of the traditional owners, the Yugambeh people.
The circular economy strategy for Yarrabilba, introduced by Lendlease in 2019, aims to make Yarrabilba Australia’s first circular economy community. This strategy focuses on reducing waste, recycling more products, reliance on cleaner power, and regenerating the environment. It focuses on materials, energy, water, and transport, with initiatives such as recycled water infrastructure, solar panels, autonomous vehicles, electric vehicle charging stations, large-scale composting, leasing of appliances for homes and local market-scale gardens. The community is in the early stages of its journey towards circularity, with the project set to be completed in 2042
Since 2010, KNg has been the Principal Civil Consulting Engineers for various precincts of the project, overseeing the design of over 4,800 residential allotments and the construction of more than 3,600 lots to house approximately 10,500 residents.
KNg has played a crucial role in the development of infrastructure, including sewer pump stations and trunk water infrastructure. Their involvement underscores a commitment to sustainable development, infrastructure excellence, and the overall well-being of the community in the Yarrabilba project.
Innovative solutions have been a hallmark of KNg’s involvement. Negotiations led to the successful implementation of an alternate pressure–gravity hybrid reticulation system. This system, featuring a specialised air valve arrangement, has not only reduced the number of traditional sewer manholes but has also increased line lengths between inspection openings. Remarkably, this approach has allowed for the retention of more trees along the route.
Project Statistics:
- Major Four lane Roads: 10km
- Sewer Pump Stations: 3, the largest being 25,000EP and 127 l/s
- DNRME Referable Dam Structure
- Three Fauna crossings including a rope ladder
