During the summer, water consumption increases significantly. This is why each of us looks for effective solutions to avoid excessively high water bills. Collecting rainwater appears as ⟨2⟩an option that is both economical and environmentally friendly⟨/2⟩. However, this water has characteristics that should be taken into account during its treatment.

Advantages of rainwater harvesting for the pool

Collecting rainwater allows for autonomy and ⟨3⟩satisfying water needs⟨/3⟩, whether for the entire house or for the pool, without depending on the public network, which constitutes a positive action for the planet.

Filling a pool requires a large amount of water, so using rainwater allows ⟨4⟩reduction of bills⟨/4⟩, especially after recouping the initial investment.

Setting up a rainwater harvesting system can also qualify for ⟨5⟩financial aid⟨/5⟩ for its installation and increase the value of your property.

Finally, it helps compensate for small drops in the pool’s water level caused by use, evaporation, or the lowering of the water level before preparing for winterization.

How to recover rainwater to fill your pool

The first solution that comes to mind for filling the pool is to use “tap water.” However, we are sometimes tempted to use rainwater without knowing how to collect it.

Depending on the type of home and weather conditions, rainwater recovery systems can vary considerably. A preliminary calculation is necessary based on precipitation, roof area, and water needs.

An interesting option is ⟨6⟩to install underground rainwater storage tanks⟨/6⟩ made of concrete, as this helps regulate the pH of rainwater, which is often acidic. Additionally, this solution integrates well into the garden, as these tanks can easily be concealed. They are equipped with filters to remove debris and leaves.

A more affordable solution would be to use ⟨7⟩outdoor tanks⟨/7⟩, which are less expensive and simpler to set up.

Adapted treatment for a pool with rainwater

Rainwater is generally softer than tap water, but it can also be more acidic. It also contains a certain number of fine particles and impurities. To avoid cloudy, greenish water or the appearance of algae, it is best to follow a few recommendations.

Above all, it is advisable to carry out a ⟨8⟩complete analysis of this water⟨/8⟩ in order to know its composition and treat it with the appropriate products (disinfectants and pH regulators). When filling, it is recommended to activate the forced filtration mode to remove all remaining debris and impurities, then treat the water with chlorine. Anti-algae products can also be very useful.
