Eric Singleton Bird Sanctuary Wetland Design

Share on:

We have placed a key role in the reconstruction of the Eric Singleton Bird Sanctuary, one of the largest wetland rehabilitation projects of its kind ever undertaken in Western Australia.

The deteriorating manmade wetland was experiencing poor water quality in both the wetland and the adjacent Bayswater Brook. This in turn was impacting bird numbers, water quality of the Swan River and public amenities.

To remediate this, GHD designed a solution to divert water from Bayswater Brook into the reconstructed wetland, which passively treats the water over 25,000 m2 and reduces pollutants flowing into the Swan River. It is expected to prevent 1.35 t of nitrogen, 200 kg of phosphorous, and around 40 t of sediment and other rubbish from entering the river.

Through a series of ponds, control weirs and vegetated treatment zones, the rehabilitated wetland has improved water quality, and associated landscaping and civil works for public access and amenities. It is also providing improvements to habitat for key avian species.

The project was awarded the 2016 Engineering Excellence Award in the Environment category.

Engaged by the City of Bayswater, GHD was the principal designer and construction supervisor with WBHO Civil performing the construction works.

Natural Resources


Our scientists, ecologists, analysts and resource economists design robust, cost effective and scientifically based natural resource management (NRM) solutions. We work with water authorities, local government, land management agencies, planning authorities, legal firms, urban developers, NRM and agri-businesses, traditional owners corporations, and companies planning infrastructure projects (such as dams, irrigation, agricultural enterprises, wind farms, and mining and energy provision). We’re known for our practical, solution-based approach to ecologically sustainable development.

By working with GHD, you can draw on our skill in ecological, natural resource and agricultural impact assessment, restoration, biosecurity and landscape planning, resource economic analysis, constraints mapping and geographic spatial analysis and community engagement, and capacity building to deliver practical and value-added management outcomes.
