Recycled water, hot rocks combine in unique WA development

It might be one of the final parts of one of Perth's most prominent urban renewal projects, but a Subiaco development is set to introduce a couple of firsts of its own.

The Australian Fine China development, one of the last pieces in the Subi Centro jigsaw is set to showcase recycled water and geothermal energy in a way not before seen in WA, and which its proponents say will reduce energy use by half.

The proposed $380 million mixed-use development, which received the final tick from planning minister John Day recently, will see the 4.4 hectare Hay St site eventually transformed, with about 300 residential dwellings and a hoped-for 2300 office and retail workers.

However, the Subiaco Redevelopment Authority development is probably of most interest for its approach to the environment. Neither recycled water nor geothermal energy have been incorporated into mixed-use developments before.

A central rainwater storage system will supply at least 59 per cent of the development's potable hot water needs - with more expected - and a still-to-be-approved shallow geothermal system will be used for heating and cooling.
