Leaks are among the biggest water wasters. If your premises have a water meter, check all taps are off overnight and no machines are using water. If the meter reading changes overnight, there could be a leak. If you can’t access your water meter, ask your landlord.
Washing machines, dishwashers, toilets, showers, taps and urinals are all places where you could potentially be wasting water. Look for ways to be more water-efficient like:
- Use low-flow showerheads, tap aerators and half flush toilets.
- Keep hot water at the recommended 60ºC to avoid unnecessary mixing with cold.
- Check for toilet leaks with a few drops of food colouring in the cisterns. The colour shouldn’t appear in the bowl without flushing.

If your site has a stormwater drain, eliminate any possible causes of contamination, including litter, dirt and soil run-off into the drains. This all ends up in our rivers and seas.
Ask your council if a litter filter is in the drain. If not, you might want to get one and be sure to clear it regularly.
