How to collect and reuse rainwater?

How to collect rainwater?

In addition to being economical, collecting rainwater is also an ecological action. The French climatic conditions would ensure that the roofs can have the capacity to collect at least 1000 liters of rainwater per square meter annually.

If you put the necessary arrangements in place, this recovery is done through the installation of a water collector. So, it is better to store rainwater for later use than to have it pour into your sumps and gutters. The water collector can be both above ground and buried.

The above ground water collector

Also called a tank, the above ground water collector is a tank that is placed at the level of the gutters to divert the water to their storage point. It suffices to equip the tank with a tap to collect the water. Better yet, you can also connect it to a pipe. With a relatively low cost, you will find tanks from 150 to 1000 liters. However, you will need to install a crapaudine in order to protect yourself from deposits of leaves or plants.

Underground water recuperator

Often buried in gardens in the form of sumps, it collects a large amount of water. It can also store between 3,500 and 20,000 liters depending on the model chosen. In short, it will simply take a cistern, pumps and maintenance tools as materials to collect rainwater.

How to reuse rainwater?

Even if the collector once installed allows you to collect rainwater easily, it is clear that its mode of use is regulated by law and that you cannot do anything with it. Indeed, the recovered rainwater is used to:

  • Water the gardens and vegetable gardens. Rainwater contains elements that promote plant development. Since gardens and vegetable gardens consume a lot of water, stored rainwater will save you drinking water.
  • Fill your pool. Swimming pools consume an enormous amount of water annually. Rainwater, once treated, can be used to supply your swimming pool.
  • Clean. For your household water uses, rainwater will be very useful for cleaning the garage, the floor, etc.
  • Wash your linens. Rainwater is an excellent alternative for flushing toilets, washing the machine, especially if you have a large family.

The reuse of rainwater is therefore a real asset for households. The inconveniences are small compared to the benefits of its recovery. One of the most expressed disadvantages is the arrival of mosquitoes when the tank is in the garden. However, with a little lemon to repel them or a tub placed in a nook far from your garden, you will be little bothered by these insects.
