Long Term Recycled Water Release Plan

Work has commenced on our long term solution for the city’s excess recycled water.

For the latest information please see our Long Term Recycled Water Release Plan project page.

Recycled water is produced by treating sewage that comes into the City’s Sewage Treatment Plants to stringent health and environmental standards so it is suitable for particular uses. Approximately 155 million litres of sewage is produced each day from our toilets, showers, kitchens and laundries which is processed at our Sewage Treatment Plants.

These sewage treatment plants are located at Pimpama and Coombabah to service the northern Gold Coast and Merrimac and Elanora to service the south.

The sewage treatment process including the collection, treatment and disposal of recycled water is an integral part of the service we provide our customers.

Recycled water supports sustainable business

Using recycled water is a sustainable climate resilient water supply option and can reduce costs for your organisation.

Recycled water is not for drinking purposes however it provides many benefits to many organisations across the Gold Coast:

Where does the excess recycled water go?

While the City remains one of the largest urban utility users of recycled water, usage currently accounts for up to 20 per cent of all the recycled water produced. So what do we do with the excess?

Approximately 115 million litres per day of excess recycled water, treated to stringent health and environmental standards, is released into the ocean at the Seaway (Nerang River entrance) on each outgoing tide. Excess recycled water has been released into the ocean via the Seaway since the early 1980s and is licensed by the Department of Environment and Science (DES).

The performance of this system is monitored and reported to DES in accordance with strict operational performance criteria. These include location, timing, volume and quality of excess recycled water releases. We also participate in the regional Ecosystem Health Monitoring Program undertaken by the independent Healthy Waterways Pty Ltd. The Broadwater achieved an ecosystem health grade of A in the most recent Healthy Waterways report card in 2019.
