Introduction
Rainwater harvesting is a practice that has been gaining popularity over the years. It involves collecting rainwater and using it for various purposes such as irrigation, household chores, and even drinking. However, not all states in the US allow this practice. In some states, there are restrictions on collecting rainwater – these states are Arkansas, California, Colorado, Georgia, Illinois, Nevada, Ohio, Utah, Virginia, Washington, and Wisconsin. The restrictions may include the size of the rainwater harvesting system, the use of a licensed plumber, the need for a permit, or the prohibition of using rainwater for certain purposes.
On the other hand, other states have no restrictions or offer incentives for rainwater collection. States like Alabama, Alaska, Delaware, Louisiana, Maine, Mississippi, Montana, Nebraska, South Carolina, South Dakota, Tennessee, and West Virginia have no restrictions on rainwater collection. Some states like Arizona, Florida, Hawaii, Kansas, Maryland, Michigan, Minnesota, New Jersey, New Mexico, North Carolina, North Dakota, Oregon, Pennsylvania, Rhode Island, Texas, and Wyoming offer incentives for rainwater collection.

States Where It Is Illegal to Collect Rainwater
While it is not illegal to collect rainwater in the United States, some states impose restrictions on it. The states where collecting rainwater is restricted are Arkansas, California, Colorado, Georgia, Illinois, Nevada, Ohio, Utah, Virginia, Washington, and Wisconsin. The reasons for the restrictions may vary by state, but some common reasons include concerns about the impact on downstream water users, concerns about the safety of the collected water, and concerns about the impact on the local ecosystem.

In California, the restrictions are in place to protect endangered species that rely on water sources in the region. In Utah, the restrictions are in place to ensure that there is enough water available for downstream users and to protect water quality. Despite the restrictions, some of these states still allow rainwater collection for certain uses, such as landscaping or toilet flushing, with the appropriate permits and restrictions in place.
