What do the regulations say about using rainwater for swimming pools?
First of all, using rainwater to fill a swimming pool is subject to specific rules in France and other countries, as it involves health issues. Although rainwater is considered a non-potable resource , it can be used under certain strict conditions.
According to regulations, rainwater should not be directly connected to the drinking water network to avoid cross-contamination. It is also imperative to filter and treat it before using it in a swimming pool.
In addition, some municipalities impose specific standards on collection and storage systems, particularly in terms of tanks and safety devices. It is recommended to check with your town hall or local authorities to ensure that your installation complies. These measures aim to protect public health and guarantee clean and safe water.
What are the financial benefits of using rainwater for swimming pools?
Filling a swimming pool with drinking water can be a significant expense, especially in areas where water is expensive or restricted. By using rainwater, you can save a lot on your water bills. With an efficient collection system, you could even supply your pool for free. In addition, financial assistance is available for the purchase of a rainwater recovery system.
How can using rainwater for your pool reduce your environmental footprint?
Using potable water to fill a swimming pool can be seen as wasteful, especially during times of water shortages.
By collecting rainwater, you preserve this precious resource and reduce the pressure on local water treatment infrastructure. You also reduce your carbon footprint by avoiding the energy needed to treat and transport drinking water.

How to collect and filter rainwater for your swimming pool?
While rainwater harvesting is an attractive alternative, it must be carefully filtered to ensure the safety of swimmers. Let’s look at the steps involved in obtaining clean water that is suitable for use in your pool.
Types of collectors and choice of tank
To collect rainwater, an efficient system starts with the roof.
Water that runs off the roof is collected through a gutter system and then directed to a collector that filters out the first impurities. This collector removes large debris, such as leaves or insects, before the water is stored in a tank.
Tile roofs are often preferred over metal roofs because they release fewer harmful particles. It is also advisable to install a pre-filter on the gutter to retain large particles such as leaves and debris and improve the quality of the stored w
Safety Precautions to Consider Before Using Rainwater for Your Pool
Handling and storing rainwater requires precautions to ensure the safety and quality of the water and those who bathe in it. Here are the main measures to take:
System maintenance : Make sure gutters, water collector and accessories are cleaned regularly to avoid the accumulation of leaves, dirt or bird droppings, which can contaminate the water. Also check the tightness of your tank to prevent the infiltration of external pollutants.
Protection against algae : tanks must be opaque and stored away from sunlight. Citerpack plastic tanks , thanks to their opacity, prevent the growth of algae that can quickly make the water unusable for the pool. Preventative treatments can be added to the stored water.
How to treat rainwater for your swimming pool?
After collection and filtering, treating rainwater is essential to ensure safe swimming. Although rainwater may appear pure, it can contain impurities such as bacteria and pathogens, making regular treatment essential.
Water quality methods and monitoring
Maintaining clean and safe pool water requires careful monitoring .
Weekly testing of the main parameters is essential to ensure the chemical balance of the water and prevent health problems for bathers.
It is essential to regularly monitor water quality by testing parameters such as pH (ideally between 7.2 and 7.6) and hardness (between 150 and 250 ppm). This ensures a good chemical balance and prevents skin irritation or damage to pool equipment.
To simplify these tasks, there are now easy-to-use manual test kits that measure pH, chlorine, hardness, and other parameters in just minutes.
Connected water analyzers are also available that offer real-time monitoring of chemical levels directly on your smartphone, allowing you to react immediately if there is an imbalance.
Conclusion
Using rainwater to fill your swimming pool is both an ecological and economical approach, but it requires precautions in terms of rainwater recovery, filtration, and water treatment.
By choosing Citerpack’s high-quality flexible tanks , you are opting for a reliable and durable solution, which guarantees efficient management of rainwater while ensuring the safety and quality of the water.
