Rainwater harvesting is more than just a sustainable practice; for many, it’s a smart and cost effective way to manage water resources, especially in challenging locations or climates. Whether you’re looking to reduce your water bill, supplement your water supply, or address drought concerns, installing a rainwater harvesting system can be the perfect solution. However, while it’s possible to harvest rainwater anywhere in the United States, some states offer better conditions and incentives than others, making them particularly ideal for this eco-friendly practice.
Below, we highlight the five best states for rainwater harvesting containers – where the practice is not only encouraged but also practical and supported. If you’re a homeowner, farmer, or business owner in these states, you’ll find it easier than ever to conserve water and reap the benefits.
1. Arizona
Why Arizona is Ideal:
Arizona’s arid climate and average annual rainfall of less than 13 inches make rainwater harvesting an ideal practice for a growing population. Residents and businesses alike are increasingly aware of the importance of water conservation in the face of frequent droughts and limited natural water resources. Rainwater harvesting provides a lifeline for gardens, landscapes, and other household or commercial needs.

State Policies and Incentives:
Arizona takes a proactive approach to promoting rainwater harvesting. The state offers eco-thoughtful homeowners tax credits for installing rainwater harvesting systems. Additionally, the regulations for water collection and storage are supportive, encouraging both residential and commercial use. Programs in cities like Tucson offer rebates of up to $2,000 for rainwater harvesting systems, making it easier to invest in sustainable water solutions.

How NTO Tank Helps:
The National Tank Outlet supplies durable tanks specifically designed to withstand Arizona’s intense heat. With UV-resistant polyethylene tanks in a variety of sizes to metal rain tanks and large capacity corrugated steel water tanks, homeowners and businesses can confidently store and use the amount of rainwater they want and need. Whether you need a compact tank for gardening or a high volume tank for larger applications, NTO Tank has you covered.

2. Texas
Why Texas is Ideal:
Texas is known for its diverse geography and variable rainfall patterns. While some areas, like Houston, receive significant rainfall, others, such as West Texas, experience prolonged droughts. This variability makes rainwater harvesting not only beneficial but essential, particularly for ranches and rural properties where access to municipal water systems can be limited. Urban areas like Austin have also embraced rainwater harvesting as a way to combat increasing water scarcity.

State Policies and Incentives:
Rainwater harvesting is highly encouraged in Texas with its user friendly regulations and financial incentives. Both state and local governments promote water conservation through rebates, grants, and tax breaks. Municipalities like San Antonio offer generous incentives to homeowners who install rainwater catchment systems that can help offset costs significantly.

How NTO Tank Helps:
For properties across Texas, NTO Tank offers a wide range of rain tanks and sizes to meet different collection needs. From small residential tanks to large volume models perfect for ranches, farms, and other businesses customers can rely on the durability and functionality of our tanks to effectively and safely store rainwater for irrigation, livestock, and more.

3. California
Why California is Ideal:
Water scarcity is a significant issue for many areas in California, where prolonged droughts have become an unfortunate reality. With some of the highest water costs in the nation, Californians are increasingly turning to rainwater harvesting as a way to offset water expenses and adopt environmentally sustainable practices, especially for outdoor water needs.

State Policies and Incentives:
California supports rainwater harvesting through rebates and incentives, particularly in urban areas like Los Angeles and San Diego. These programs encourage the installation of harvesting systems for both stormwater management and water conservation. Statewide initiatives also promote the use of collected rainwater for landscaping and other non-potable purposes.

How NTO Tank Helps:
For urban properties with limited space, the National Tank Outlet offers slimline doorway tanks purposefully designed for storage in smaller areas. Homeowners and businesses in California can benefit from products that make rainwater harvesting easy even in densely populated neighborhoods.

4. Oregon
Why Oregon is Ideal:
With its lush landscapes and abundant rainfall, Oregon is one of the easiest states to implement rainwater harvesting systems. The often eco-conscious population of Oregon embraces sustainable water practices, making rainwater harvesting not just practical but also culturally aligned with the state’s values.

State Policies and Incentives:
Oregon has favorable regulations for rainwater harvesting. It’s legal to collect rainwater for both potable and non-potable uses, provided the water is gathered and treated properly. Additionally, certain regions offer financial incentives to encourage the adoption of rainwater harvesting systems, especially as part of stormwater management initiatives.

How NTO Tank Helps:
NTO Tank provides a range of affordable rain tanks designed to handle the consistent rainfall in Oregon. These tanks come with rain accessories, such as filter screens and overflow ports for a cleaner water supply free from debris. Residents can make the most of Oregon’s frequent rains with our dependable, long lasting tanks.

5. Washington
Why Washington is Ideal:
Washington, particularly its western region, receives significant annual rainfall, making it a natural fit for rainwater harvesting practices. The state also prioritizes water conservation to help fight seasonal droughts and support its growing urban population.

State Policies and Incentives:
Washington is one of the most rainwater harvesting-friendly states. State laws allow residents to collect rainwater for both potable and non-potable uses without requiring permits in most scenarios. Local governments and municipalities further promote sustainable water practices through rebates and assistance programs, particularly for stormwater management efforts.

How NTO Tank Helps:
The National Tank Outlet’s wide range of UV-resistant poly and metal rain tanks can endure Washington’s rainy winters and changing climate conditions. We offer a variety of tank types and capacities to suit all property sizes, from small residential spaces to expansive commercial setups.
