Is Collecting Rainwater Illegal in America?

As a person who lives off-grid I, like many others in my situation, understand just how important water is. In America there is a wide diversity of environments, consequently this valuable resource that is abundant in some areas is limited in others.

I am fortunate, in that I have a spring, a bore hole, and yet I just can’t let that infrequent rainwater flow away without capturing some of it.

However, when in 2012 Gary Harrington, a resident in Oregon was sentenced to 30 days in jail and fined $1500 for harvesting rainwater on his land rumors started to spread that it was illegal to collect rainwater.

Can it possibly be against the law to collect water that falls from the sky and flows from your guttering when it rains.

Is collecting rainwater illegal in America?

Collecting rainwater is not illegal according to federal law, however many states, have legislation that relates to water in general and more specifically how rainwater is collected and what it can be used for.

State legislation varies dramatically according to geographical location, climate, and the levels of water that are available. Some states encourage rainwater collection whilst others have restrictions.

Rainwater is a part of the ecosystem that provides the water that passes along rivers and streams into underground aquifers that create a supply that is available for everyone to use.

Water is such a valued resource it is also a commodity. Utility companies utilize the water from underground aquifers and reservoirs both natural and those that have been constructed to sell through a network of pipes that supply household and Industry.

The average household in America will consume in excess of 12 000 gallons per month and Industry consume huge quantities. Hence water utility companies gain huge revenue from this natural water that falls from the sky.

If we look at the specific case of Gary Harrington, it transpires that he collected 30 million gallons of water by building 20 ft high dams and reservoirs on his own property.

He was diverting the flow of water from watercourses that flowed through his property, and it was this that was illegal not the act of collecting rainwater.

To understand the complexities of collecting rainwater in the United States we need to look at each state to see what if any legislation is in place regarding the rights to harvest rainwater.

State Legislation

Alabama

Alabama is one of the states that does not have any restrictions on collecting rainwater as it considers it the right of the property owner to collect the water that falls on the property. It does in fact encourage the collection.

The Alabama University published an extensive guide to demonstrate some very practical and technical instructions regarding the best ways to collect and store rainwater.

Alaska

Alaska is also a state that does not have restrictions regarding rainwater, or perhaps it should be classed as snow. Due to the climate in Alaska it is difficult to establish a traditional water supply network.

Consequently, residents have only limited options available to them. Community water collection points are available as a water supply but manually collecting and transporting the water is difficult and can result in contamination.

It is far simpler and cost effective to collect rainwater on site. Environmental protection agencies studies show that rain water collected on site is a safe supply of unpolluted water.

Arizona

The state of Arizona does not have any restrictions regarding collecting rainwater that falls on your own property. The state recognizes that with a dry climate and an increasing population that water resources are limited.

Consequently, they would prefer residents to collect rainwater to supplement existing supplies rather than collecting water from rivers or underground.

The University of Arizona have produced a comprehensive guide that provides information regarding how to build a rain water collection system.

Arkansas

Although the state of Arkansas is happy for residents to collect rainwater it does place restrictions on what the water can be used for and how it is collected.

Rainwater cannot be used for drinking, but it is fine for bathing cooking and of course irrigating gardens and crops. The state does also insist that any collection system be installed by a licensed professional who is able to install the system using the relevant installation codes.

Clearly the state has concerns regarding potential Health and Safety issues that an inadequately designed system could present.

California

Home owners in California can collect rain water from their roofs without any restrictions.

However, a landscape contractor who is providing a rain water collection system for a swimming pool, outside cooking facilities or a decorative water feature such as a pond or fountain is required to hold the necessary certificate of qualification as prescribed in the 2012 Rainwater Capture Act.

Any provision of this type of landscaping made by a homeowner or a non-licensed contractor would be considered illegal.

Colorado

Historically Colorado had some of the strictest legislation regarding water and more specifically the collection of rainwater. The state has changed the legislation considerably in 2016 after a study showed that only 3% of water that fell as rain made its way into streams and underwater aquifers.

The 2016 legislation does however still impose several restrictions. The main restrictions specified in the legislation is that a maximum of two rain barrels holding 110 gallons in total can be stored. The water cannot be used for drinking only garden irrigation.

The state recognized that its growing population and the geographical and geological situation of the state would almost certainly mean that demand would outstrip its resources within 10 years.

The report recognizes that rainwater collection already being utilized in country areas should be extended into residential communities.

Idaho

The residents of Idaho are free to collect rainwater with certain provisos. Water that does not flow into a stream or river can be collected on private property providing it does not cause interfere with any existing water rights of other property owners.

The state does therefore not place any restrictions on rain water collection and offers advice on how best to construct effective rain gardens.

  1. Thank You verry informative! I have been using the barrel system for the garden for several years. I have been looking into another source of drinking water for some time. I am on a neighbor’s public water line and it would cost about 15000$ to put in my own line in. I have been seriously looking into a insulated above green cistern so it could be cleaned out occasionally. Any ideas ?
