Is Rainwater Harvesting Illegal?

No, rainwater harvesting is not illegal. There aren’t any federal laws against it. Any rules and restrictions around rainwater harvesting are at the state-level.

Some states such as Delaware and Florida encourage residents to collect rain water and offer incentives to do so. However, some states have minor restrictions on methods and uses.

What Types of Restrictions Exist?

Residents in states with restrictions can still harvest rainwater, but there might be limits on how they collect it, how much they can collect, and how they can use it. Some examples are below.

1. Must Be Used for Non-Potable Purposes

For instance, Arkansas and Illinois don’t let residents drink the rainwater they collect. They can use it to water the lawn or wash the car, but they cannot drink it.

This restriction is to protect public health.  Per the CDC, rainwater can contain bacteria, parasites, viruses, and chemicals that could make you sick if it is not filtered properly.

2. Must Use Roof Surfaces

Some states restrict how rainwater is collected. For example, in Oregon, only roof surfaces may be used for harvesting rainwater.

Meaning residents can't simply put a free-standing rain barrel, bucket, or tarp to collect water.
