Water use, sustainability, and efficiency by choosing quality systems and materials, and providing environmentally friendly solutions.
By minimising water use, and making good materials choices, you can reduce running costs, cut demand on community infrastructure, and reduce harm to the environment.
For water supply and drainage, the first consideration is building users’ health and safety. A system is not sustainable if it does not meet basic needs for drinkable water and for safe disposal of waste.
But, subject to health and safety requirements, it is good practice to design systems that support efficient and sustainable use of water, energy and materials.
For water supply, there are many things to consider, ranging from the type of water heating used to the layout of pipework to specifying appliances and fixtures. These decisions can have a significant impact on water and energy use over the life of a building.
For wastewater treatment, the key decision is whether to connect to the mains sewerage network, treat wastewater on-site, or a combination of both. Either way, it is important that health and safety requirements are met.
Stormwater runoff places demand on infrastructure and can carry contaminants into waterways such as streams and the sea.
All water and wastewater costs are borne by building owners and occupiers, through rates and user charges.
By designing, building and renovating homes that use water efficiently, you can help keep these costs down.
Reducing water use also benefits the environment by, for example, reducing the need to draw more water from rivers and waterways, reducing demand for energy, and reducing the need to build new infrastructure for supply and disposal.
