- Roof Material – The material of the roof is not as important as contaminants that
may be on the roof.
- Slope – The slope of the roof affects how quickly water will runoff during a rain
event. A steep roof will shed runoff quickly and more easily clean the roof of
contamination. A less-steep, flatter roof will cause the water to move more slowly,
raising the potential for contamination to remain on the catchment surface.
- Sizing a Catchment Area – The size of the catchment area or roof will determine
how much rainwater that you can harvest.
- Size of the reservoir or tank available.
