Typically, water is taken from a well or borehole. But if this water is not enough or you want to have a backup source. One of them is collecting rainwater from the roof of the house.
In the water of atmospheric origin, salts are almost wholly absent. It is softer than the central water supply. The natural softness of such water provides an effective wash with low consumption of detergents.
The content of harmful components in the rain depends on the nearby large enterprises of the metallurgical, chemical, oil refining industries, large transport hubs, and megacities.
A roof made of galvanized metal, natural tiles, polyvinyl chloride, other materials that do not contain asbestos, lead, and copper are suitable for collecting rainwater. Slate cannot be used.
The materials forming the storage tank should have a significant volume and should not change their properties over time and affect the chemical composition of the water.
Storage tanks are located at or below ground level, so a pump is needed to operate the water supply system.
The pump can be used both submersible and surface. The input node does not differ from the input node to a private house.
It should be remembered. It is not recommended to drink rainwater. It is permissible to wash dishes and take a shower with rainwater only after its multi-stage filtration. However, it is pretty suitable for watering a garden, lawn, wet cleaning, or for flushing the toilet.
