Visitors, new tenants or an increase in the number of residents at your home can lead to higher water usage.
For example: Having one extra visitor stay for a 90-day billing cycle (using the average daily water usage of 168 litres per person per day) would add about $51-$55 to your bill (depending on your regional pricing).
Our handy tool, My Usage Tracker, available online in My Account, helps you graph you water usage over time, so you can easily see the impact visitors have on your daily usage.
Automatic irrigation systems can use thousands of litres of water each week, and the automatic top-up device on your water tank could be set to draw water from the town water supply, even when the tank is close to being full.
Please check these systems to ensure they are operating at the correct level and are not faulty. Your tank should be set to top up to about 10% to 15% below full capacity, leaving enough room for regular rainfall to fill the rest.
We also recommend you follow our 10-point checklist to make sure you're not using water more than you need to:
