A proposal to raise Victoria’s minimum water efficiency standards for toilets, taps and showerheads in all homes and businesses where new fixtures are being installed has been launched.

On average, more than half of the water consumed within the home is used in the shower. More efficient shower heads and taps do not just cut water use and bills; they reduce the energy required to heat water to deliver even more savings.

The proposed updates would raise minimum standards for kitchen and laundry taps, showers and toilets from 3-star to 4-star with basin taps increasing to 5-star in homes and 6-star in offices and commercial buildings.

Modelling estimates that over the next decade, water demand could outstrip supply across greater Melbourne by 95 billion litres of water per year even with the Victorian Desalination Plant running at full capacity.

While the Water Security Plan is investigating all viable solutions to meet future water demand, the most cost-efficient and effective way to relieve pressure on our supplies is to use less water in and around our homes and for businesses to do the same.

The proposed water efficiency requirements would apply to all registered plumbing work in new and existing buildings. The changes will make Victorian homes and businesses the most water efficient in Australia.

A Regulatory Impact Statement has been prepared which examines the costs and benefits of the proposed regulation changes including two alternative options.
