Hawks Nest Recycled Water Scheme

Work is almost complete on a scheme to reuse treated water from the Hawks Nest Sewerage Treatment Plant for irrigating the nearby golf course, sports fields and open spaces.
With the golf course using over a million litres of water on a hot summer’s day – sourced from the area’s groundwater supply – and the sewerage treatment plant producing over 800 thousand litres of water a day, the project makes good sense.
Currently MidCoast Water returns the treated water from the plant back to the water cycle through the sand dunes, however working with the golf course and other sites provides a beneficial use for the water and actively reduces the amount of groundwater extracted.
This scheme will see more than 120 million litres of water reused each year, which is approximately 40 per cent of the total effluent treated at the Hawks Nest plant.
Irrigating with the treated water will also reduce the need for fertilisers at the golf course and sports fields, as trace nutrients such as nitrogen and phosphorous are present in the treated water.
The project initally involved irrigation of the golf course only and the recycled water was to be suitable for irrigation with restricted public access. Additional funding from the Australian Government Department of Sustainability, Environment, Water, Population and Communities (DSEWPC), under the National Water Security Plan for Cities and Towns has meant that additional sites can utilise recycled water. The funding has also meant that the plant will undergo additional augmentation to result in a higher quality recycled water which will be fit for irrigation with unrestricted public access.
The project has involved upgrading the Hawks Nest plant and the construction of a transfer system to connect the plant to the Hawks Nest Golf Course, Myall Park and Providence Bay Park.
 The beneficial reuse of treated water on golf courses has been taking place for some years, with Kew and Maitland Golf Courses examples of successful reuse projects.
