Benchmarks for water use

Understand how much you can save

By comparing how much water your business uses to how much water similar, water-efficient businesses use, you can set achievable targets. Saving water does much more than add to the bottom line.


How saving water helps your business

Businesses are responsible for around 25% of all water used in Greater Sydney. Could your business use less water, more effectively? By achieving a best practice benchmark, you can:

  • pay less on water use, energy use, chemical use, wastewater discharge and trade wastewater charges
  • save on maintenance and capital costs of equipment by managing water better
  • reduce your environmental impact by reducing your site's carbon emissions, demand for water from our dams and discharge that must be treated before it's released into rivers and oceans
  • build your brand as an environmentally conscious provider, improving your corporate social responsibility.

3 steps to calculate, compare and track

The key to using water more effectively is to understand where your business uses it.

We've used a childcare centre as an example to demonstrate the steps to achieve a best practice benchmark. The business activity of a childcare centre falls under 'Childcare and preschool education'.
 

Step 1  Calculate your current business benchmark

  • Start with your key business activity indicator. The key business activity indicator is the business activity or variable that affects how much water your business uses.
  • Quantify your water usage in units that align with the benchmark for your business type. The benchmark may be in megalitres (ML), kilolitres (kL) or litres (L).
  • Calculate the daily water use to align with the benchmark. Divide your water usage by the days shown on the water bill (a quarter can be from 90 to 92 days).
  • Calculate your business benchmark by dividing daily water use by the key business activity indicator.
Childcare centre example

The childcare centre takes 30 children a day on average. This is its key business activity indicator. The water usage on its latest quarterly bill is 90 kL (1 kL = 1,000 L). To calculate the childcare centre's business benchmark:

Water usage on last bill
90,000 L


÷

Days shown on last bill
90 days


=

Daily water use
1,000 L

Daily water use
1,000 L


÷

Key business indicator
30 children


=

Childcare centre benchmark
33 L per child per day

Step 2  See how you rate against similar businesses

Once you've calculated your current business benchmark, you can see how it rates against benchmarks for a similar business in the dropdowns below. When you compare, you can see if there's potential to improve your water management practices, reduce your water usage and use water more effectively.

Childcare centre example

The business benchmark of 33 L per child per day puts the childcare centre in the fair range for the 'Childcare and preschool education' water-efficiency benchmark. There's an opportunity to improve practices and reduce water usage to enable it to fall within the best practice range of less than 20 L per child per day.
 

Step 3  Track your benchmark over time

By comparing your business benchmark over time, you can:

  • measure how your business is performing
  • verify the benefits of action taken to improve performance
  • identify problems for investigation if water use increases unexpectedly.
