A clear understanding of your water use will help to identify unexpected patterns such as leaks or faulty fixtures.
To make sure you know where water is being used at your site, follow these steps to complete a simple water audit.
1. Monitor and record your water use
Read your meter daily and record the readings to understand how your business uses water. Establishing water use patterns over time will make it easy to identify spikes in your water use that need to be investigated.
How to read your meter
- Read your meter by recording the black (kilolitres) and red (litres) numbers from left to right, at approximately the same time each day
- Calculate daily water use by deducting the previous meter reading from the current reading
We recommend additional morning and night meter readings for 2 weeks every quarter to assess that the overnight water use is acceptable for your business. If it isn’t you will need to investigate it.

2. Check water using appliances
Identify all water using devices and processes in your business and check regularly. It will help you detect leaks and faulty fixtures early on and repair as soon as possible to minimise water loss.
- Taps and showers – worn washers, leaking fixtures
- Toilets and urinals – stuck or worn float valves
- Dishwashers and glasswashers – leaking unit, taps or plumbing
- Plant and equipment – identify wherever water is used in your business and regularly inspect
Are your appliances water efficient?
Investing in water efficient appliances will also go a long way in helping you reduce water use.

3. Create a water management plan
A water management plan will help you to identify inefficiencies and potential water savings, prepare an action plan and establish a dedicated team to implement the plan. It also provides a process for monitoring and reporting on your water saving actions.
