All water supply options can contribute to water security and other valued outcomes and each community should consider all options within their local context. We have focused some specific effort on purified recycled water for drinking as in Australia it is the option that has often been left off the table.
This toolkit contains a range of resource materials on purified recycled water for drinking. WSAA is currently building a new Water360 website that will contain these resources, and more on other water industry topics. This toolkit, including individual items, is updated regularly.

This 90-minute webinar looks at how San Diego famously overcame public rejection of reuse in the 1990s and is now building a scheme that will supply one-third of the city’s water. WSAA is joined by Jeffery Pasek who steered the project from its early days while at the City of San Diego.
|Are we alone on this road?||
This 90-minute webinar explores purified recycled water for drinking schemes around the world. WSAA is joined by Michael Killick, City of Cape Town and Brendon Theunisse, Zutari to discuss water reuse in Cape Town after Day Zero.
Treating purified recycled water to drinking water standard involves taking it through a multi-step treatment process, in which each treatment step plays a specific role in ensuring the highest quality water. The overall process can vary in each city, to suit its geographic and other circumstances.
These short animations (around a minute each) show how several treatment steps work, and the El Paso video shows an overall treatment process.
