What you can do
Report drips and leaks
Report leaking taps, showers, toilets and urinals, to either your Building custodian or raise a service request.
Turn it off
Turn off taps fully and check for drips.
Wait until it's fully loaded
Only turn on the dishwasher and washing machine when it is fully loaded.
Take shorter showers
Try to limit shower time to 3-5 minutes. That's more than enough time to be clean and hygienic. Play your favourite song (as long as it's not American Pie) and aim to finish by the time the song ends.
Not only does it save water but it significantly reduces the energy used to heat the water.
