-Why we want to use this system :

We want to use the rainwater not to use the drinking water.

For exemple: toilet,washing machine , garden.

-How to use the rainwater collection:

1.We must use a slope roof,because the flat roof is bad.The best materials for the roof are : tile,slate,glass and zinc.

2.Provide an overflow.

3. choose a tank for yours needs.

4. choose a pumping water system.

-Rainwater collection system :

1.Rainwater falls on your roof.

2. it falls into the gutters, along the wall of the house (possibility of a first anti-leaf filtration called a crapaudine).

3.via a pipe that connects the gutters to the tank, the water goes  to the rainwater tank.

4. then it is stored in the tank.

5.Distribution :  The water is pumping or it goes to the tap  : the water is distributed in the house via a independent network of the city water network.
