<strong>2007</strong> Centre for Plant & Water Science <strong>Annual</strong> <strong>Report</strong>SUNRISE AT 1770 WASTEWATER TREATMENT AND WATER RECYCLINGREFURBISHMENTSUMMARYSunrise at 1770 is a premier development on the <strong>Queensland</strong> Discovery Coast that has its ownwastewater and water recycling system. The treatment chain is unique and provides a Class A+recycled water. CQ<strong>University</strong> during <strong>2007</strong> updated the treatment chain and installedspecialised zeolite and scoria filtration tanks for salt management.Sunrise at 1770 is a sustainable sub-division of 172 lots located on the coast of <strong>Central</strong><strong>Queensland</strong>. Sunrise is a high-end development being a gated community where an economicpremium is placed upon the environment. It is completely off-the-grid in regards to its waternetwork and has implemented an integrated decentralised system. Each house has a minimumof 48 000 L of rainwater tank storage to provide the potable supply. Supplementary potablesupply is available from a nearby aquifer. The zeolite and scoria filtration tanks installed byCQ<strong>University</strong> reduce the concentrations of sodium and ammonia in the recycled water.Recycled water is provided to each house for toilet flushing and external water usage through adedicated purple pipe system. Recycled water is also used (a) to irrigate a large (200 000seedling) endemic native plant nursery used for revegetation, (b) to supply a community carwash,and (c) in emergencies for fire-fighting water. The decentralised network provides thefire-fighting water for the development primarily through the aquifer and for localised bush-firefighting through the rainwater tanks. The decentralised water system has successfully providedthe water requirements for the development throughout four years of drought without the needto bring in water from external sources. In <strong>2007</strong> Sunrise at 1770 won the most sustainabledevelopment in <strong>Queensland</strong> from the Urban Development Institute of Australia (UDIA), wonAustralia’s most sustainable development (UDIA) in 2008, and made the finals in the UnitedNations Australian 2008 World Environment Day Awards for Water Design.Figure 1A: Beach Club at Sunrise at 1770Figure1B: Zeolite and Scoria Filter TanksPROJECT STAFF Principal Investigators: Ben KeleCo-supervisors: David MidmoreOthers: Ross Percival, Jordanna Bembridge, Barry Hood, Denis BalkinFUNDINGMidell Developments Pty Ltd<strong>Central</strong> <strong>Queensland</strong> <strong>University</strong>34
