Melbourne’s water supply comes from alpine catchments and has faced restrictions in the past. Even outside restriction periods, reducing water usage cuts bills and protects against future scarcity. These tips focus on practical changes that make a real difference.
1. Fix Leaks First
A dripping tap wastes 3,000+ litres per year. A running toilet cistern wastes 60–260 litres per day. A leaking toilet or tap isn’t just an annoyance — it’s measurable water and money wasted every day. Fix all leaks before investing in any other water saving measure.
2. Install a Water-Efficient Showerhead
Showers account for approximately 34% of household water use in Melbourne. Replacing a standard showerhead (12+ L/min) with a 3-star WELS rated model (9 L/min) saves approximately 25% of shower water use. 4-star and 5-star models (7–6 L/min) save more, though perceived comfort decreases at the lowest flow rates.
A showerhead replacement is not licensed plumbing work in Victoria — it’s a simple DIY task (unscrew old, screw on new with thread tape). Cost: $30–$150 for a quality WELS 3–4 star model.
3. Check WELS Ratings on All Fixtures
WELS (Water Efficiency Labelling and Standards) rates appliances and fixtures on a 0–6 star scale. For taps, toilets, and showerheads, aim for 3 stars minimum. 3-star is also the minimum required for landlords to pass water costs to tenants in Victoria.
When replacing any fixture, choose the highest WELS rating you can comfortably use. The difference in purchase price between a 3-star and 4-star tap is usually under $50; the water saving over 10 years is hundreds of litres.
4. Dual-Flush Toilets
If your Melbourne home still has a single-flush cistern, replacement with a dual-flush unit saves significant water. A 3-star dual flush toilet uses 3L (half flush) / 4.5L (full flush) vs. 12L+ for an old single flush. Toilet replacement in Melbourne costs $600–$950 fully installed.
5. Upgrade to a Heat Pump Hot Water System
While primarily an energy efficiency upgrade, heat pump systems also reduce water waste because they heat water more consistently — less running hot water before it arrives at the tap (compared to systems where the pipes run cold). Combined with a tempering valve set at 50°C, wait time for hot water is minimised.
6. Check for Hidden Leaks Annually
Use the water meter test once a year: turn off all outlets, note the reading, wait 30 minutes. Any movement = a leak. Hidden leaks from flexi hoses, under-slab pipes, or garden irrigation can waste thousands of litres before causing visible damage.
