Queensland-First Wastewater Treatment Plant Wins Engineering Excellence Award

Logan Water’s Cedar Grove Environmental Centre won the 2020 Australian Engineering Excellence Award for Queensland by Engineers Australia in a virtual award ceremony this week.

The $116.7 million project was delivered by a public and private sector partnership involving Logan Water, Economic Development Queensland, Downer, Cardno and WSP.

 

Logan is one of Queensland’s fastest growing areas. To service its thriving communities, new and improved water and wastewater infrastructure is being delivered that benefits the regional economy, environment and communities of today and tomorrow.

 

Cedar Grove Environmental Centre features the state’s first Wastewater Treatment Plant (WWTP) to benefit the environment through membrane bioreactor technology and constructed wetlands to achieve record low nutrient levels, and offsetting remaining nutrients through catchment restoration. A total of 37,000 trees have been planted on the restoration site to offset vegetation removal by developers across Logan. The site is also a centre for research and a community recreation reserve.

 

 

The project combined cutting edge wastewater treatment technologies with environmental enhancement, community-led site master planning and innovative project delivery methods. Logan Water plans to open the gates for community access in October.

 

Dean Maguire, WSP’s Section Executive of Water in Queensland says, “What began as a WWTP has been reimagined as a sustainable community and environmental asset to benefit today’s residents and future generations. Our Water, Environment and Planning teams have worked closely as part of the Logan Water Alliances and Partnerships to deliver future ready innovations that benefit our communities through continued collaboration with our partners, industry and communities.”

As part of the Logan Water Alliance, WSP delivered the following services: design visualisation tools (utilised for design and operability reviews); structural design; electrical design, pre-commissioning and commissioning; instrumentation and controls design; development of 3D interactive operation and maintenance system; odour and noise assessments; cultural heritage assessment; environmental assessment and management; ecological assessment and management; compliance management; rehabilitation works; and operational management plan for the wider site.

 

Since 2009, WSP has proudly been part of the Logan Water Alliances and Partnerships, alongside Downer and Cardno, delivering a sustainable water future for the City of Logan. The program has grown to more than $100 million a year and spanned three contracts (Logan Water Alliance from 2009 to 2015, Logan Water Infrastructure Alliance from 2015 to 2020 and the current Logan Water Partnership from 2020 until at least 2025).
