There are many procedures that have become fashionable for collecting rainwater thus saving the internal consumption of this resource. However, there is a centuries-old system that was used long ago, using only natural and simple materials such as sand, gravel and charcoal to filter water with great efficiency.
In this traditional water collection system, rain travels from the roof of the house to a barrel through pipes, gutters or gutters that any structure has.
This is a procedure that was very popular in homes until the early 20th century. But It is a lost and forgotten method like any other, due to a society that is increasingly estranged from conventional wisdom and nature in general.
However, some books, as well as private internet portals such as Ecoinventos, are responsible for protecting and recovering these uses.
The container normally used was a wooden barrel, but any other tank that actually performs the same function and does not emit rust or other contaminants can be used.
This rainwater is not only better for washing clothes, but also very more suitable for watering our gardens and crop fields when it is scarce in times of drought. The water, free of chlorine and other types of salt, brings vitality to the fields. Many users of such barrels assure on the Internet that their plants look much better using water from the rain.
By attaching a spout or faucet to the barrel, a hose can be connected, making irrigation work easier.
but this water It is used not only for irrigation, but also for many other domestic uses, while cooking.
How is water filtered for human consumption?
Now, to use this rainwater For human consumption, it is imperative that the liquid be filtered for ingestion under maximum safety conditions.. Also, the barrel must not have been previously occupied by chemicals. In case of using another type of container, care should be taken that it does not release polluting particles and that it is very clean inside.
It is also recommended that kegs have a fine mesh filter on their surface to ensure they are protected from insects or other unwanted particles.
Materials such as small stones, medium stones, gravel, coal and fine sand are required to filter the water inside the barrel.. By forming layers of different densities with these elements, it becomes easier to filter the liquid until it is consumed.
The layer that will cover the bottom of the container will consist of medium-sized stones, with a slightly smaller layer of small stones on top of it, with a few centimeters of fine sand on top of it. gravel.
Next, charcoal will be deposited (an essential element as it will absorb heavy metals and toxic substances), then another layer of gravel will be added and more small stones will be added on top of the centimeter gravel. The process will be completed by using a layer of medium size stone on the barrel surface.
The density of each layer varies depending on the dimensions of each container, therefore it is worth giving more precise advice on this matter.
Experts on the subject recommend choosing hard maple charcoal to make this age-old invention, which some know by hearsay and know to be an invention used in villages decades ago.
