States Where It Is Illegal To Collect Rainwater In US!

Rainwater collection is the absorption and disposal of water and then reusing it for on-site use. It makes it simple to use the Earth’s hydrologic cycle by simply building a device in one’s own house. It lowers the demand for water services and increases recycling efforts for residents to catch rainwater on their land. In homesteading, rainwater collection is popular.

Well, there are no rules or limits on rainwater collection in the Federal Government. Most states allow and even encourage people to collect rainwater. For example, Rhode Island, Texas, and Virginia promote rainwater collection by providing a tax credit or deduction for rainwater collecting devices.
