Frequently Asked Questions
How accurate is the water usage calculator?
The calculator uses WELS standards and Australian water usage data, providing estimates within 10–15% of actual consumption, depending on input accuracy.
Can I use this for BASIX compliance?
Yes, the calculator helps identify water-efficient fixtures to meet BASIX water targets, though professional assessments may be required for formal compliance.
How do I find my water tariff?
Check your water bill or contact your provider (e.g., Sydney Water, Melbourne Water). The calculator uses a default tariff of $1.50–$2.50 per kL, typical for Australia.
What are WELS fixtures?
WELS (Water Efficiency Labelling and Standards) fixtures, like 4-star toilets or 5-star showerheads, use less water. Find them at waterrating.gov.au.
Tips to Reduce Your Water Usage
- Install WELS fixtures: Upgrade to 4-star toilets (4 LPF) and 5-star showerheads (9 LPM) to save up to 50% on water use.
- Fix leaks promptly: A dripping faucet can waste 30 liters daily, and a running toilet up to 200 liters.
- Shorten showers: Reducing shower time by 2 minutes saves 18–30 liters per person daily.
- Use efficient appliances: Choose WELS-rated washing machines and dishwashers to cut water use by 40–50%.
- Optimize outdoor use: Water lawns early morning or evening and use drip irrigation to minimize evaporation.
