Collecting rainfall water and channel it to a storing container is something that has been done from ancient times and such waters were historically used for farming purposes. With the growing population in cities and the change of water supplies such as rivers made the first systems become unused.

At present, for the reasons stated above, rainfall water is being re-used again. House and building roofs are involved in collecting the water, and through its channelling it is taken to a storage container. After a simple treatment, whenever it is necessary, the water is ready to be used again.

Apart from the savings in water, in places where the water is little polluted, this system allows to save up to a 50% on soaps and detergents. Grey waters can be used on the WC, to wash vehicles, to water plants and even in washing-machines.

Small installations that would collect little water can also be done, especially in places where the demands of such water is not high, as for instance for watering the plants.

Studies on the feasibility of any project, either big or small, will be done at Instal·lacions JF with outmost rigor and responsibility, and always trying to bring solutions to the problems that may arise.
