World Water Day 2026: How Pool Covers Can Help Conserve Water
March 22nd marks World Water Day, a United Nations initiative raising awareness about global water conservation and access. While water covers 70% of our planet, only a tiny fraction is accessible fresh water — just 0.0003% of the world’s water is readily available in lakes, rivers, and shallow groundwater. Every drop counts, and even recreational water use, like swimming pools, has an environmental impact.
Pools and Water Usage: A Closer Look
Take France, the European leader in swimming pools, with over 3.2 million pools nationwide. Assuming an average pool size of 8m x 4m x 1.5m, that’s 48,000 litres per pool. Collectively, these pools hold over 153 billion litres of water. Evaporation is a major contributor to water loss — outdoor pools can lose over 512 million litres per day if left uncovered, roughly the equivalent of 160 litres per pool, or more than a bathtub a day.
With recurring droughts and increasing water scarcity, conserving pool water is essential. In response, the French government has introduced stricter regulations, including bans on topping up pools during drought warnings and restrictions on above-ground pool sales, highlighting the importance of responsible water use.
How Pool Covers Help Save Water
Using a high-performance pool cover dramatically reduces water loss. GeoBubble™ covers, can conserve up to 98% of pool water that would otherwise evaporate. This not only helps maintain water levels but also reduces the frequency of chemical dosing and backwashing — both of which consume additional water.
Even simple nightly use of a pool cover can make a noticeable difference. For instance, using RaeGuard™ on an open pool overnight can save around 32 litres of water per day, equivalent to 1mm of evaporation. For pools that are uncovered during the day, full-time coverage offers even greater savings.
Energy Savings and Sustainability
Water conservation isn’t just about preserving water — it’s also about saving energy. Heated pools lose heat as water evaporates, which increases energy consumption to maintain temperatures. High-performance covers, such as Sol+Guard™ and EnergyGuard™ Selective Transmission, help capture solar energy and reduce reliance on pool heaters. By retaining heat and reducing evaporation, these covers save both water and electricity, lowering your environmental footprint and utility costs.
Our Life Cycle Assessments (LCAs) provide a scientific breakdown of these savings. They show how GeoBubble™ covers reduce water consumption, decrease energy use, and extend product lifespan — supporting both cost savings and environmental sustainability.

Our LCA results
Our Life Cycle Assessments (LCAs) measure the total carbon impact of GeoBubble™ pool covers, from raw material extraction through to manufacturing, distribution, and end-of-life. The results show that, thanks to their long lifespan and ability to reduce water consumption, GeoBubble™ covers can deliver a net reduction in carbon emissions over their lifetime.
