The Eric Singleton Bird Sanctuary is an artificial wetland in Bayswater, Western Australia, a suburb of Perth. The Bayswater Brook discharges into the wetlands, which in turn discharges into the Swan River. In 2015, it underwent a rehabilitation project in order to improve the water quality and attract more wildlife. History Prior to the 1950s, the site of the Eric Singleton Bird Sanctuary was a seasonally wet depression. In the 1950s, it was drained. Between 1972 and 1981, the surrounding area was used for a landfill, and the site became a wetland. Due to nutrients and pollutants from runoff, the wetlands were severely degraded and experiencing frequent algal blooms. In 2015, the wetlands underwent a $3 million rehabilitation project, jointly funded by the City of Bayswater and the Department of Biodiversity, Conservation and Attractions. The project was designed so that water coming from the Bayswater Brook is cleaned and stripped of nutrients by the wetlands before being discharged into the Swan River. First, the incoming water flows through a gross pollutant trap, removing any rubbish, sediment or other large materials. The water then passes through alternating areas of shallow and deep water, which removes nitrogen and other nutrients, before flowing out of the wetland. The flow of water is controlled by a series of weirs and outlets, and in total, the process takes 48 hours from when the water enters the wetland to when the water exits. The project is projected to stop of nitrogen, of phosphorus and of sediment and rubbish from entering the Swan River each year. The project also included the creation of a publicly accessible area in the middle of the wetland. Prior to the rehabilitation project, the wetlands were artificially supplied with ground water to ensure that the wetland did not dry up. After the completion of the project, it received several awards, including from the Australian Engineering Excellence Awards, the WA Premier's Awards and the Australian Institute of Landscape Architects. In 2016, a housing development was approved by the Western Australian Planning Commission next to the wetlands, overruling the City of Bayswater and triggering significant controversy. The proposed development consisted of two large blocks, and one block was considered by the community to be environmentally sensitive and contain wetlands. In 2017, the State government provided $1.5 million to the City of Bayswater to part-fund the purchase of the block which contained the wetlands, thereby
