Water efficiency targets

Setting a target for your household

Homes that are roughly the same size, with the same number of people living in them, generally use about the same amount of water if they use it efficiently. How does your household compare? Find out now what your daily water efficiency target should be.

How to set your target

  1. On your latest bill, find the month's usage charges and your average daily usage.
  2. Then, from the 4 daily target tables below, choose the one that includes the month closest to your usage charges date range for this bill: November–January, February–April, May–July or August–October.
  3. Choose the number of people who shared your home most of the time.
  4. Choose your property size in square metres (m2).

The result shows how many litres per day (L/day) an efficient household the size of yours uses. This is your target. Compare it to your average daily usage right now.

The first box shows the start and end dates for this bill's usage charges. The black column in the second box shows the average litres per day (L/day) your household has used.

How does your household compare?
If your average daily water usage is the same as or less than water-efficient households the same size, congratulations! You're already using water efficiently.

What the targets are based on

People use water in lots of different ways around the home, and many factors determine how much water they use. To calculate the daily averages in the tables, we assumed that people in water-efficient households:

  • use water outdoors 2–3 times a week for things like maintaining their lawn and garden, topping up the pool and washing the car
  • have a 4.5-minute shower each day using a water-efficient showerhead (no more than 9 litres per minute)
  • use a dual-flush toilet
  • use a front-loading washing machine and no more than 2 loads per person per week
  • use water-efficient taps fitted with aerators
  • use the dishwasher no more than once a day
  • have a bath only occasionally
  • fix any obvious leaks around the home.
