The primary concern for water supply design in a house will always be the health and safety of the occupants, but beyond that, there are opportunities to reduce consumption of reticulated water through efficient design.
Water shortages are a regular occurrence in many parts of New Zealand, and climate forecasters say the future will bring longer periods of drought.
Designs that reduce domestic water use are often inexpensive, have minimal impact on occupant lifestyle and can save money where water is metered.
Reducing water use can also reduce energy use and give houses a smaller carbon footprint.
