2628 Plumbing and Drainage and Other Legislation Amendment Bill 23 Aug 2005<br />

because some councils have gone ahead with unique recycling schemes and amazing initiatives where<br />

grey water systems may become superfluous.<br />

The member also asked what we are doing to conserve water and to promote reuse. Of course,<br />

that is a job not only for the government and members of the opposition but also for all <strong>Queensland</strong>ers.<br />

Therefore, I take the opportunity to mention that, as well as the grey water legislation that we are<br />

debating tonight, the government is working on a number of additional initiatives to improve water use.<br />

Recently, I was pleased to announce sustainable housing initiatives that will promote the installation of<br />

rainwater tanks and water conserving technologies within <strong>Queensland</strong> homes.<br />

I thank the member for Caloundra for his support. Quite rightly he makes the point that this is just<br />

the start and that much more needs to be done. In fact, the <strong>Queensland</strong> government agrees. We<br />

recognise that a broad approach will be needed to change water consumption trends. Significant<br />

funding has been directed through the Climate Smart Communities to support many related initiatives.<br />

Those projects will support local governments in driving other initiatives such as stormwater harvesting,<br />

dual reticulation and public awareness. They will also support education initiatives of the sort described<br />

by the member, which can change the way <strong>Queensland</strong>ers think about water as a resource and,<br />

hopefully, change their behaviour. If members had not noticed it in the budget allocation, they will be<br />

pleased to hear that under the Climate Smart Communities heading, $600,000 has been allocated to<br />

Building Codes <strong>Queensland</strong> specifically to support grey water use over the next three years, and<br />

$3 million has been allocated to Building Codes <strong>Queensland</strong> over four years for a range of water<br />

conservation reforms.<br />

The member for Gladstone made a substantive contribution. She particularly mentioned the issue<br />

of irrigation systems, which she said will add expenses to the installation of grey water facilities. That is<br />

true. It is recognised that requiring subsurface irrigation piping will represent a significant proportion of<br />

the cost of systems. However, subsurface irrigation is vital to avoid public contact with water that may<br />

contain pathogens. In terms of health and safety, we are taking a conservative approach in introducing<br />

permission for grey water to be used around <strong>Queensland</strong> and we recognise that there are certain costs<br />

that go with that. However, those are costs in relation to health and safety and they are appropriate. At<br />

the same time, costs have been minimised by allowing for irrigation systems to be installed by home<br />

owners rather than by licensed plumbers.<br />

The member for Gladstone also raised the issue of kitchen grey water not being discharged<br />

through treatment systems. She rightly points out that, in future years, legislation will need to evolve<br />

further to accommodate and promote the uptake of innovative technologies. We have structured this<br />

legislation to remove the absolute prohibition on grey water use and, in the years to come, it will be<br />

possible to quite easily respond legislatively to new options for grey water management.<br />

I thank all the honourable members of the government team who have supported this legislation.<br />

Many spoke with some passion. Clearly they and their electorates have a history of showing strong<br />

interest in water conservation and sustainability in general. I thank the member for Noosa and the<br />

member for Cook, and also the members for Hervey Bay, Glass House, Thuringowa, Redlands, Fitzroy,<br />

Capalaba, Broadwater and Ipswich for their contributions. Mr Speaker, I also note that before you held<br />

your present position you too made a worthy contribution.<br />

The member for Greenslopes raised some significant issues that I would like to address. He was<br />

concerned that we ensure that grey water is used carefully in backyards so as not to cause a nuisance<br />

or in any way put at risk our health. He is quite right to be concerned. I can let him know that we have<br />

insisted on the subsurface piping irrigation system to safeguard against such things as ponding in<br />

certain areas or children who are playing in their backyard gaining direct access to grey water.<br />

Additionally, the design of systems and council approval processes will ensure that the water is safely<br />

distributed through the subsurface system. Filters on diversion devices will limit the flow of lint and solids<br />

through pipes. Councils will be able to assess whether or not soil profiles on premises are suitable for<br />

grey water irrigation. Finally, offence provisions will make it possible for councils to address any<br />

situations where systems are not effectively managed.<br />

I thank the member for Fitzroy for his generally supportive contribution. He raised the good issue<br />

of the expense of repiping, particularly involving the separation of grey water from black water. I am<br />

pleased to reassure him on this issue. While it sounds like that would be an expensive and difficult<br />

repiping job, in actual fact grey water can be easily diverted by the installation of a diversion device to<br />

laundry and/or bathroom piping before it discharges to the sewer. I particularly mention the contribution<br />

of the member for Ipswich who spoke, of course, about the various other options that we have for<br />

conserving water, including the exploration of desalination.<br />

I mention my geographic colleague, Lesley Clark, the member for Barron River. Over many years<br />

in the broader Cairns area she has kept the community and, I might say, to some degree the council<br />

honest on issues of water supply and water demand management. This has not always been popular.<br />

While wise and well based in science and sensible consideration, her words have not been welcomed<br />

by all sections of the community. Therefore, she has shown some courage to persist. Over more recent<br />

years, as many more of us have realised the importance of conserving water, we are now taking
