Effective Tips To Reduce Pool Water Evaporation To Save Water

Are you someone who is conscious of the amount of water that goes into your fibreglass pool? Homes that have fibreglass pools brisbane in their backyards can actually be more water-conservative when compared to lawns that have sprinkler systems.

You can end up using up as much as two-thirds more water if you had a lush backyard garden that you needed to water thoroughly, every day. Even if you keep your backyard as a lawn, it would still need more water for maintenance, than a fibreglass pool.

Water conservation is something that many pool owners find themselves thinking about. But what can you do to reduce your water consumption while still ensuring that you can use your pool properly?

How Does Evaporation Affect Your Pool?

The number one way that you could be losing the water in your pool, is through evaporation. It’s been seen that evaporation alone can account for upwards of 50% of the loss of water, over time.

So if you haven’t been adding water to your pool, but left it alone to stagnate under the Sun, you’ll notice the amount of water in your pool going down.

Investing in a pool enclosure is one of the most effective tips to prevent water from evaporating and providing a protective barrier for the pool.

The enclosure blocks the sun’s rays from directly hitting the water, reducing the amount of evaporation and keeping the water temperature more consistent.

It also protects the pool from debris, animals, and other elements that could contaminate the water. Pool enclosures also provide privacy and create a more relaxing atmosphere around the pool.

Evaporation is a natural process that occurs anytime the surface of the pool is exposed to either air or the wind.

During the process of evaporation, water molecules will end up rising up towards the surface and then turn into a vapour form. After this, the water will end up escaping into the atmosphere.

Your pool will still experience evaporation during a night that’s relatively cool as well. If you have a heated fibreglass pool, then this is more likely to occur.

This means that depending on what kinds of weather conditions you have in your area, the amount of water in your fibreglass pool can drop regularly. It can go down by as much as one-quarter of a single inch, every day.

The good news is that there are various things that you can do, in order to combat your evaporation problem. Let’s look at what these are.

How To Prevent Swimming Pool Water Evaporation

1. Keep Your Pool Covered

When your pool is not in use, consider keeping it covered. Adding pool covers is the top tip that most pool professionals will give you when you ask them how to reduce the effects of evaporation.

When you keep your fibreglass pool covered, you ensure that the amount of water lost through evaporation is dramatically reduced.

This especially applies to days that are hotter as well as nights that are colder. You can reduce over 90% of water lost through evaporation, by just keeping your pool covered. There are other benefits associated with using pool covers as well.

You’ll be able to ensure that more water stays in your pool. You’ll also be able to trap the heat that’s in the pool, within as well. This means that the water in your pool will be warmer, and you’ll be spending less on pool heating costs.

There are various pool covers available at all price ranges, and using a wide variety of materials. You can get a simple pool cover or a fully automated one.

If you want just one solution that can help you combat the problems caused by evaporation, then investing in a pool cover is perfect for you.

2. Consider Liquid Solar Blankets

Maybe you don’t want to add an unappealing cover on top of your pool. In this case, is there an alternative available to you? The answer is yes, there is.

Liquid solar blankets aren’t as effective as pool covers, but they can still help in reducing the amount of water lost through evaporation.

These liquid blankets are much lighter than water. You can think of them as microscopic films that lie on the surface of your pool.

They can also be found in several forms, such as bottles, tablets, and more. All you need to do is add the product to your fibreglass pool, and its contents will automatically be dispersed across your pool.

What you get is a molecular barrier that not only traps heat inside the pool but also prevents the evaporation of water. You can find liquid blankets that need to be added every day, or ones that need to be added just once a month.

3. Keep Water Features Turned Off

You might have waterfalls, fountains, or other water features in your pool. But they also end up increasing how much water surface is left exposed to the elements. Since more water surfaces are left exposed, you lose more water through evaporation.

Should you have any water features that spray the water up or have a rain-like effect, then you’ll lose water faster as a result. This is as the surface of the whole water droplet is exposed to both heat as well as air. This makes them more likely to evaporate.

When you aren’t using your pool, ensure that your water features are turned off. Not only will you be losing less water through evaporation, but you’ll also be spending less on energy bills required to run the pool pump.

This is because it’s the pool pump that keeps your water features active.

4. Reducing The Water Temperature

A simple way you can reduce the effects of evaporation on your pool water is by reducing the temperature of the water in your fibreglass pool.

This is because warmer water tends to have molecules that move faster, and as a result are vaporized more quickly. Water that’s cooler also tends to be more resistant when it comes to dispersing into the air.

If you think you’re not going to use your pool for a few days, then keep your pool heater off through those days. You’ll save on energy bills and also reduce the evaporation of water from your pool.


A major way through which your fibreglass pool loses water is through evaporation. But there are several things that you can do to reduce the amount of water lost through evaporation.

From adding a pool cover to reducing the temperature of the water in your pool, this guide details what you can do to keep the water in your pool, inside your pool.
