How Do I Reduce Pool Water Evaporation?Updated a month ago
In Australia’s hot, dry climate, evaporation can drain your pool (and wallet) fast. The average pool loses 30,000+ litres annually to evaporation—but with the right strategies, you can slash water loss and keep your pool topped up.
1. Use a Pool Cover
The #1 evaporation fighter, covers reduce water loss by 70–95% depending on type:
Solid thermal covers: Block evaporation completely and retain heat. Best for overnight use.
Solar bubble covers: Float on the surface, trapping heat and cutting evaporation by 70%. Ideal for daytime heat.
Automatic safety covers: Seal the pool entirely (bonus: child safety).
Pro tip: Pair with a pool roller for hassle-free handling.

2. Try a Liquid Pool Cover
How it works: A biodegradable chemical layer (monomolecular film) spreads across the water’s surface, slowing evaporation by 30–50%.
Pros:
No physical handling—perfect for irregularly shaped pools.
Safe for swimmers and compatible with most filters.
Once a month application
Cons:
Less effective in windy areas.
Needs consistent reapplication.
Great for: Apartments, spas, or pools where covers aren’t practical.

3. Reduce Wind Exposure
Wind accelerates evaporation. Create barriers with:
Hedges or shrubs: Plant 1–2m tall windbreaks on windy sides.
Privacy screens or glass fencing: Stylish and functional.
Shade sails: Cut UV exposure and wind while cooling water.
4. Lower Water Temperature
Warmer water evaporates faster. For heated pools:
Reduce heater settings by 1–2°C.
Run heaters at night (cooler air = slower evaporation).
5. Check for Leaks
Evaporation vs. leak:
Evaporation: Uniform water loss (≈3–5cm/week in summer).
Leak: Sudden drops, soggy soil, or algae despite balanced chemicals.
Test it:
Mark water level with tape.
Turn off pump and autofill for 24 hours.
If loss exceeds 3cm, suspect a leak.
Aussie-Specific Water-Saving Tips
Refill with rainwater: Install a tank to harvest stormwater.
Adjust pump times: Run at night (cooler temps = less evaporation).
Shallow pools: Keep water levels slightly lower (less surface area).
Avoid overfilling: Water spilling from splashing wastes hundreds of litres.
