Domestic use
Rooftop rainwater harvesting is used to provide drinking water, domestic water, water for livestock, water for small irrigation, and a way to replenish groundwater levels. [<- Wikipedia]

My Edits:

Non Potable use for rainwater harvesting (livestock, irrigation, toilets, etc.) helps reduce the cost spent for city water on site when doing tasks that do not require purified water.

Potable supply through rainwater harvesting also lowers a site's water bill but requires more purification and is more expensive to install. This is also dependent on the sanitation codes in the city that the system is being set up in. Purification to meet Potable demand can be met through chlorine, UV, or micro filters
