The first step in rainwater collection is to catch the rain as it hits the roof (in most cases).  The rainwater collection area may also be a hillside or even a parking lot (non-potable uses).  Metal roofs, seamless gutters, and high quality gutter covers are recommended for rainwater collection.  Once the rain is in the gutters, it is channeled through a pipe design and then through a filter to remove any debris.

The rainwater collects in a tank where it is stored for later use.  Rainwater collection systems typically include pressurization pumps to convey the water to the point of use.  

For non-potable purposes such as irrigation, livestock, or commercial processing, the water may need little (if any) filtration.  For potable, whole-house use, the filtration and sterilization requirements are much more defined.
