NSW Government today announced work has begun on a $32 million project that will pave the way for the supply of over 4 billion litres of recycled water each year to Sydney’s west and inner west and help reduce sewer overflows in southwest Sydney.

This important construction work will provide the foundations for the privately-owned Rosehill Camellia Recycled Water Scheme, a project that will deliver more than 4 billion litres of recycled water to some of Sydney’s biggest industrial water users.

Construction starts today on building diversion structures and storage facilities at the two treatment plants and a wastewater storage tank at the Potts Hill reservoir site.

Once complete, these works will make treated effluent from Glenfield and Liverpool sewage treatment plants available to be extracted from the Liverpool Ashfield Pipeline and further treated for reuse by industrial customers.

The $100 million Rosehill-Camellia Recycled Water Scheme will be the first scheme in the country to distribute recycled water to a network of industrial users in a built up area.

Sydney’s disused gas pipes will be reused to distribute recycled water across the system to industrial users with the initial infrastructure upgrade will supporting around 60 jobs.

Up to 300 jobs in total will be created during the construction of the Rosehill Camellia Recycled Water Scheme, which when up and running will save more than 1,700 Olympic sized swimming pools of water each year.

From 2011, AquaNet Sydney, part of the Jemena Group, and Veolia Water Australia, the private operators of the Rosehill-Camellia Recycled Water Scheme will extract treated effluent from the pipeline, treat it at the recycled water plant to be built at Fairfield and transfer it through a network of pipes, including disused gas mains.

The recycled water will be used in cooling towers, for irrigation and as boiler feed by seven customers including Shell, Visy Paper, Marubeni Australia Power Services and Rosehill Gardens.

Both Sydney Water and the private sector are investigating the potential to further expand the use of treated effluent from the Liverpool Ashfield Pipeline for recycling.

Supplying treated effluent for recycling will reduce demand for drinking water and help reduce the risk of sewage overflows to the Georges River during wet weather.
