“Knowledge shared by the CRC WSC was

combined with the expertise of SEW and Villawood Properties

to identify specific new opportunities”

“how innovative strategies can enable an urban community

to be more resilient to climate change , more sustainable, and more

liveable”

Purchaser Education and theSales Process

• Homes built within Aquarevo are required to be Aquarevo compliant

• Builders were educated on the design changes required for a pre-approved design

• The pre-approval process was vital for the home builders to ensure ease of sales

• Regular meetings with SEW to ensure the initiatives are understood and adopted.

• Construction process meetings with SEW and builders to ensure the construction process works smoothly with the inclusion of the initiatives.

Challenges• It hasn’t all been smooth sailing! It’s taken time and patience to get ensure Aquarevo

initiatives meet regulatory requirements and have buy-in from key partners/suppliers:• Department of Health engagement re the rain to hot water system• EPA approvals for the estate treatment plant• Builder house designs – meeting Aquarevo specifications• Purchaser education• Bringing Council along for the journey• Creating a joint venture between a Government organization (South East Water) and private

enterprise. Each organization has had to adapt and be flexible in the way we approach issues, and how planning/execution is handled.

How it works…

At the centre of the partnership is a deep commitment to the overarching vision of Aquarevo.

Through open communication and collaboration, all parties have adapated to create an Aquarevo way of doing things, to bring the vision to life.
