Advice

Plan for long term water conservation by users of the building and surrounds

Plumbing installation and appliances

Minimise the distance between hot water cylinders and taps (this will save water and the cost of unnecessary piping and energy costs).
Specify low flow rates and maximum levels of fluctuation for fixtures.
Choose plumbing fixtures that have built-in flow restricting devices.
Install fixtures and appliances that comply with highest available water efficiency rating (e.g. 4.5/3L dual flush toilets, water efficient showerheads) or if possible, install composting toilets or waterless toilets and urinals. Check the Smart Approved WaterMark website or the WELS Rated Products Search for efficient products. The savewater!® product library includes information from both sites.

Collect rainwater for storage and re-use in tanks, ponds, dams, swimming pools or underground tanks.
Consider the feasibility of greywater use - water from sinks, baths, showers or clothes washers (greywater) can be recycled to flush toilets or irrigate plants. Be aware that it is important to properly maintain these systems, as poor maintenance can lead to poor quality water which can be hazardous to human health and the environment.
If greywater use is not feasible at the moment, design the plumbing to assist future adaptation.

Apply Xeriscape gardening (low-water use) principles to gardens and landscapes
Use water efficient irrigation systems
Mulch flower beds and around plants
Maximise infiltration of water to recharge groundwater
Install rainwater collectors and covers for pools to collect water and minimise water evaporation
Indigenous (local) plants generally have low water requirements and are suited to local climatic conditions
