States Where It Is Illegal to Collect Rainwater 2022

some states currently have restrictions on how much rainwater can be harvested and how it is collected; however, it is not entirely illegal to collect rainwater in any of the 50 states. some of these restrictions believe that harvesting would disrupt the natural flow of rain into streams and bodies of water on land. According to a study in the journal Scientific World, the amount of rainwater collected by individual households would have little or no effect on the hydrological cycle, especially since homeowners would use this water for their patios or gardens to return to the ground.

In western states, there are restrictions because old water laws stated that all rainfall belonged to existing water rights owners. these laws were known as pre-appropriation laws or “first come, first served” laws for settlers in the old west. Rainwater harvesting poses a health concern, as some of the water may be unsafe and unsuitable for potable (ie drinking) purposes. this is something that legislators should take into account.
