Why recover rainwater?

• The rainwater collected and used in the home can be an alternative for all those who build their homes to which regulations prohibit the discharge of roof water into the sewer.

Rainwater is an inexhaustible natural resource. Once fallen on the roofs, we reject it improperly to the sewers, which represents a huge waste. There are several possibilities to recover and use 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 and that it must be used on a different network from 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 top up the water in the pool. With the abundance and proliferation of private pools, we are impoverishing drinking water resources. Rainwater is a good alternative, it can be filteredand processed to meet your requirements.

• The third idea is the valorisation of rainwater throughout the habitat. In fact, recovering rainwater from the roofs is easy:

It is enough to have a house, a little land to add a recovery tank, a pump, a good element of treatment and filtration to distribute rainwater throughout the house. Rainwater has so many benefits that it is important to use it throughout the home.

Financial benefits

Nowadays, water becomes a rare commodity. Its price continues to increase. It has doubled in the last 10 years and it is announced for future years an increase in the price of water of the order of 5 to 10% per year. It must be clear and know that it is not the water itself that determines its price but its treatment and routing to the tap.

The drinking water network in France is in an old state and does not always meet the requirements of European standardséennes. This implies a program of overhaul to standards spread over several years with a cost that will be borne by the consumer.

The treatment of water costs more and more. The quality of the water, at the base, being more and more mediocre requires an implementation more and more expensive to always obtain the same quality at the tap with a cost that will always be borne by the consumers.

Rainwater of better quality falls free on our property and with inexpensive treatment, it can be used in a more noble way than we do today.

• Rainwater is soft, so need less detergent for all your household chores. Detergent requirements decrease by 40 to 60%. For a family of 4, the savings per year can be close to 200 to 250 euros.

• By its softness, the rainwater protects your appliances: more aggressiveness of the limestone, more use of salt for the dishwasher, more calgon or limescale product, cumulus clouds are protected, less of electrical consumption to heat the water to temperature.

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

Ecological benefits


The use of rainwater has various ecological benefits. It makes it possible to preserve the use of water tables which are already at a critical level during the summer periods (several French departments in water restriction).

• It allows, when it is recovered in a tank, to be a buffer zone in case of heavy rains with sewage treatment plants that have great difficulty managing this large influx of water. This influx can cause a drinking water unfit for consumption.

• The rainwater collected and used and then polluted in the house makes recycling easier for wastewater treatment plants. In fact, rainwater falls on public roads loaded with heavy pollutants that are even more difficult to treat for wastewater treatment plants.
