Rainwater collection has become popular due to its numerous benefits, such as conserving water and providing an easily accessible water source for gardening or drinking. However, there can be confusion regarding the legality of rainwater harvesting.
On the federal level, there are no restrictions regarding collecting rainwater. However, laws and regulations surrounding this practice are primarily determined by the individual states. Thus, knowing your local legislature’s stance on rainwater collection is important.
Some states may have certain restrictions regarding the amount of harvested rainwater and the equipment used for collection, while others may actively encourage the practice through guidelines, handbooks, or incentives.
Dive in with me as we embark on this journey to unravel the true story of rainwater harvesting regulations. While no state paints it black and white as ‘illegal,’ it’s pivotal to be armed with the knowledge to ensure your efforts are both fruitful and lawful.

Why Is It Illegal in Some Places
As a homeowner, you might wonder why collecting rainwater is illegal in some places. It comes down to water rights and the concept of prior appropriation, which dates back to the days of the Old West.
In some western states, water is considered scarce, and settlers established rules to distribute water fairly among residents. These rules prioritize those who started using the water and claim rights to it. This system, known as prior appropriation, means that people who already have a claim on a body of water can assert their rights over newcomers.
Because of this system, rainwater that falls on one person’s property might be considered as part of a larger natural water cycle that includes streams and other bodies of water nearby. When you collect rainwater on your property, you might unintentionally divert water that would have ended up in these streams and the larger water system, to which someone else has rights.
Making it illegal to collect rainwater in some places is an effort to protect the rights of those who already have claims to the water and maintain the balance of the overall water system. It helps ensure that the water remains available to those who rely on it for their livelihood and sustenance.
It’s important to note that rainwater collection is not illegal everywhere. Most states have specific regulations in place that address the practice. Colorado and Utah have strict limitations, while other states have varying degrees of regulation. Always check with your local authorities to understand the rules that apply to your area.
Legal Aspects and Regulations
When it comes to the legality of collecting rainwater, I should mention that there is no federal law in the United States that prohibits it. Instead, regulations and permits for rainwater collection are typically managed at the state level. Each state has its own approach, and some may require permits, have restrictions on the amount of rainwater you can collect, or even impose specific guidelines on the usage of rain barrels.
I’ve found that the majority of states in the US have no strict regulations or even encourage rainwater harvesting. However, certain states like Arkansas, California, Colorado, Georgia, Illinois, Nevada, North Carolina, Ohio, Oregon, Rhode Island, Texas, and Utah have some regulation in place. Makre sure to check with local authorities, the Department of Health, and the American Rainwater Catchment Systems Association (ARCSA) to understand your area’s specific guidelines and rules.
While collecting rainwater, adhere to property rights and comply with individual states’ regulations. If you want to be a rainwater collector, you should also be aware of initiatives like the “Water for 2060 Act,” which seeks to promote efficient water usage by using technologies such as rainwater capture systems. This act helps reduce the demand for surface and groundwater resources, which can benefit the environment and water supply.
The Effect of Rainwater Harvesting
Conserving water has a positive environmental effect, especially if used for gardening large-scale farming, and other non-potable activities like cleaning machines. Collecting rainwater for reuse reduces the demand on our water supply but also helps to alleviate some of the pressure on our cities’ infrastructure.
One major benefit of harvesting rainwater is its potential to mitigate drought. In areas where water scarcity is a recurring issue, rainwater collection systems can serve as a valuable resource. With proper storage and treatment, this captured rainwater can be used for various non-potable purposes, such as watering plants, flushing toilets, and even washing clothes.
In addition, rainwater harvesting contributes to the reduction of stormwater runoff. As we all know, heavy rain can quickly overwhelm storm drains in urban areas, leading to an increased risk of flash flooding. We can then help reduce the water running around our cities and counties during storm events.
It’s also important to consider the environmental benefits of utilizing a local water source. Using captured rainwater rather than relying on water transported from distant reservoirs saves energy. It’s a small step, but when adopted by many, it can have a positive impact on reducing greenhouse gas emissions.
Special Cases and Incentives
Regarding rainwater collection, some unique situations and incentives are offered by states for residents to consider.
For instance, in Georgia they offer a Rainharvest System Tax Rebate of up to $2,500 for installing rainwater collection equipment. This is just one example of how states can incentivize using rainwater harvesting systems.
On the other hand, California passed the Rainwater Capture Act in 2012, allowing landowners to install, maintain, and operate rainwater capture systems for potable and non-potable uses. This act is just one example of how states are working toward addressing the growing interest in rainwater harvesting and its incorporation into water laws.
At times, specific bills, such as House Bill 7070 or Senate Bill 32, have been introduced to clarify water laws further and promote rainwater harvesting. These bills and others like them aim to encourage installing rainwater collection systems on rooftops and recognize the value of these methods when managed by entities like the Department of Natural Resources.
The Science Behind Rainwater Collection
In the hydrological cycle, precipitation means the rainwater falls on the Earth’s surface, where some evaporates back into the atmosphere. The rest of the water seeps into the soil, replenishing the groundwater table or becoming surface runoff.
Collecting rainwater at home reduces dependence on municipal water supplies and contributes to conservation efforts. As Mother Nature already purifies the water through the rain cycle, you can directly use rainwater for non-potable purposes, such as watering your plants or flushing the toilet. In addition, with proper filtration and treatment, it can be safely used for drinking and cooking.
It’s also important to note a growing interest in studying the effectiveness and benefits of rainwater harvesting systems for individual homes. Research has shown that rainwater collection can aid in maintaining the natural flow of water bodies, minimizing the disruption of local ecosystems.
Rainwater collection systems can also range from simple barrels to more complex systems with pumps and filters. With these simple methods, homeowners can significantly reduce their water consumption and contribute to the sustainability of local water resources. Not only that, but rainwater can also be a cost-effective alternative to procuring water from municipal sources.
Frequently Asked Questions
