Why recover rainwater?

• Rainwater harvested and used in the home can be an alternative for all people who build their home to which regulations prohibit the discharge of water from roofs to sewers.

Rainwater is an inexhaustible natural resource. Once it falls on the roofs, we throw it back into the sewers, which is a huge mess. There are several ways of recovering and using rainwater:

• The main idea on the subject is to collect rainwater to water his garden and wash his car. There are several solutions on the market to perform this type of service, knowing that the water used is raw waste and must be used on a network other than the public network. Unless you use a filtration and water treatment system that will allow you to use the existing public network. But the investment would not be profitable.

">• The second idea is to use rainwater to fill and refill with water from the pool. With the abundance and proliferation of private pools, we are depleting drinking water resources. Rainwater is a good alternative, it can be filteredand processed to meet your requirements.

• The third idea is the valorization of rainwater throughout the habitat. Indeed, recovering rainwater from roofs is easy:

All you have to do is have a detached house, a little land to add a recovery tank, a pump, a good treatment and filtration element to distribute the rainwater throughout the house. Rainwater has so many advantages that it is important to use it throughout the house.

Financial Benefits

Nowadays, water becomes a rare commodity. Its price is constantly increasing. It has doubled in the last 10 years and there is an announcement in future years of an increase in the price of water in the order of 5 to 10% per year. You have to be lucid and know that it is not the water itself that determines its price but its treatment and routing to the tap.

The drinking water system in France is in a dilapidated state and does not always meet the requirements of the europeanéennes. This involves a multi-year upgrading program with a cost that will be borne by the consumer.

Water treatment costs more and more. Since the quality of the water at the base is increasingly poor, it requires an increasingly expensive implementation to always obtain the same quality at the tap at a cost that will always be borne by consumers.

Rainwater, of better quality, falls free of charge on our property and with an inexpensive treatment, it can be used more nobly than we do today.

• Rain water is gentle, so less detergent is needed for all your household chores. Detergent requirements decrease by 40 to 60%. For a family of 4, the economy per year can reach 200 to 250 euros.

• The softness of the rainwater protects your household appliances: more aggressiveness of the limestone, more use of salt for the dishwasher, more calgon or anti-limestone product, the cumulus is protected, less power consumption to heat the water to temperature.

• The softness of rainwater is good for the skin. City waterbeing often calcareous and highly chlorinated, it attacks the skin. Rainwater eliminates several problems due to the aggressiveness of chlorinated water such as scalp dandruff and allergic skin problems.

Environmental Benefits


The use of rainwater has various environmental benefits. It makes it possible to preserve the use of groundwater that is already at a critical level during the summer periods (several French departments in restriction of water).

• It allows, when recovered in a tank, to make buffer zone in case of heavy rain with the treatment plants which have great difficulty to manage this important influx of water. This influx can lead to water that is unfit for consumption.

• Rainwater recovered and used then polluted in the house allows for easier recycling for sewage treatment plants. Indeed, rainwater falls on public roads loaded with heavy pollutants which are even more difficult to treat for sewage treatment plants.
