Dual (purple) pipe subdivision takes off on the Gold Coast ...

Excerpt from the Courier Mail (after all their commentary on recycled water, they should get their terms correct):

Project to harness greywater

19 October 2006

Northern Gold Coast residents could be using up to 84 per cent less potable water within two years in an $80 million greywater recycling project launched yesterday.

The Pimpama-Coomera area is the first community in Queensland in which all homes will have dual-reticulation pipes – one carrying potable water and the other recycled water.

Gold Coast Mayor Ron Clarke, who helped turn the first sod for the recycled and wastewater plant yesterday, said the scheme would be up and running by the end of 2008.

"When fully implemented, it will service at least 120,000 residents in a 7000ha area and reduce the demand for drinking water in homes by 84 per cent," he said.

"Implementing such a diverse range of water-saving initiatives in one area on such a large scale is unprecedented in Australia."

Recycled water would be delivered to about 18,000 homes in the Pimpama-Coomera area via special purple pipes, Gold Coast City Council water sustainability chairman Daphne McDonald said.

The recycled water would be used for toilet flushing, garden watering and other exterior uses.
