Is it Legal to Collect Rainwater in Colorado?

Colorado Rainwater Harvesting Laws and Regulations

In Colorado, the legality of rainwater harvesting has evolved over time, subject to specific regulations and legislative changes. It’s important to understand the current legal framework that dictates how you can engage in rainwater collection.

Overview of Rainwater Harvesting Legality

You may be aware that Colorado operates under the prior appropriation doctrine, which historically complicated the legality of rainwater harvesting. However, as of Senate Bill 09-080 and subsequent House Bill 16-1005, residential rainwater collection is now permitted under certain conditions. As a resident, you’re allowed to collect rainwater if you meet two main criteria: you must be the owner of the property, and the property must have a rooftop precipitation collection system attached to a residence.

Key Definitions and Terminology

It’s crucial to know the specific terminology related to rainwater harvesting in Colorado:

• Rooftop Precipitation Collection Permit: A document issued by the Colorado Division of Water Resources allowing the collection of rainwater.
• Prior Appropriation Doctrine: The foundation of Colorado’s water rights law, which allocates water based on a “first in time, first in right” principle.

Updates and Recent Changes in Law

The legal landscape for rainwater harvesting in Colorado saw significant updates with the introduction of House Bill 16-1005. This bill allows residents with rooftop precipitation collection systems to use harvested rainwater for outdoor purposes like watering lawns and gardens. You’re now legally entitled to capture and use rainwater from your rooftop, providing a direct benefit to your property’s landscape and garden maintenance, all within legal bounds.

Colorado Water Rights and Rainwater Ownership

In Colorado, your ability to collect rainwater and the associated legal rights are shaped by the state’s unique approach to water rights. This framework determines how rainwater can be owned and used.

Navigating Water Rights for Rainwater Harvesting

Colorado’s water rights are governed by the prior appropriation doctrine, which is different from the riparian rights found in many other states. The essence of this doctrine is “first in time, first in right,” meaning those with older water rights have priority over newer claimants. House Bill 09-1129, passed in 2009, marked a shift in regulations allowing certain homeowners to collect and use rainwater. However, before you set up a rain barrel, you must understand that specific criteria and limitations apply to ensure compliance with existing water rights.

Ownership and Use of Collected Rainwater

Under the adjusted legal framework, you—as a property owner—may collect and use rainwater if your property is entitled to the use of a well or if you are served by a water district, and the collected rainwater is used on the same property, primarily for landscaping purposes. Ownership of this rainwater is contingent upon adhering to state regulations, including the quantity of water collected and the method of collection.

Legal Framework Governing Water Rights

The legal framework in Colorado is detailed and specifically outlines how water rights and rainwater harvesting are managed under the state’s law. The collection system must be designed to divert rainwater from rooftops to a storage container, and the amount is typically limited to a maximum of two barrels with a combined storage of 110 gallons. It’s important to stay informed about the current regulations to ensure your rainwater harvesting practices are within the legal boundaries.

Restrictions and Limitations on Rainwater Harvesting in Colorado

In Colorado, the practice of collecting rainwater has specific legal frameworks you must adhere to, revolving around how much water you can collect and what you can use it for.

Volume and Usage Restrictions

You are allowed to use rain barrels for the purpose of rainwater harvesting in Colorado. However, there are strict limitations on the capacity to consider. You are permitted a maximum of two rain barrels with a combined capacity of 110 gallons. Moreover, these barrels should be associated with a single family residence or multi-family residence.

Usage Limitations for Harvested Rainwater

The harvested rainwater is confined to certain uses. For instance, you can use it for watering lawns, gardens, or outdoor plants. Directing water indoors or utilizing it for potable purposes is not allowed unless you adhere to more complex regulations and obtain the necessary permits.

Zoning and Land Use Considerations

When it comes to zoning and land use, you must check any local ordinances that may impose additional requirements or restrictions on rainwater collection. These regulations, which might dictate specific land use practices, could affect the installation and placement of your rainwater harvesting system, especially concerning the roof size and structure from which you plan to collect rainwater.

Understanding Rainwater Harvesting Permits

In Colorado, the legal framework surrounding rainwater collection is precise and mandates adherence to specific regulations. To legally harvest rainwater, you must navigate the permit process, understand the relevant building codes and standards, and ensure compliance through inspections.

Permit Requirements for Rainwater Collection Systems

For your rainwater collection system, you’ll need to secure a rooftop precipitation collection permit if you are using a well, or adhere to SB09-080 if you plan to use rain barrels. Well permits are necessary for larger systems, while the law SB09-080 (Rainwater collection in Colorado) allows for the use of up to two 55-gallon barrels without a traditional permit.

Application Process and Documentation

To apply for a rainwater collection permit, you must submit an application along with required documentation demonstrating that your system follows state standards. This could include property information, intended use, system specifications, and any other details set by the Colorado water authorities. Make sure your documentation is thorough to avoid delays in the process.

Building Codes and Standards for Rainwater Harvesting

Your rainwater harvesting system must comply with Colorado’s building codes and standards. This involves designing the system to handle the area’s weather conditions, using appropriate materials, and ensuring proper installation to avoid contamination and improper drainage.

Compliance and Inspection Procedures

Once installed, your system may be subject to compliance checks and inspections to ensure it adheres to the state’s regulations. Regular inspections might be required to maintain your permit status. Stay informed about these inspections to ensure that your system remains compliant and functional over time.

Historical Background of Water Laws in Colorado

As you explore the topic of rainwater collection in Colorado, it’s crucial to understand the state’s unique water law history. This history has shaped the complexities of the current legal stance on rainwater harvesting.

Evolution of Water Rights and Policies

In Colorado, the concept of water rights has evolved significantly since the mid-1800s. Your use of water is directly influenced by the doctrine of prior appropriation, which asserts that the first person to take water from an aquifer or river for “beneficial use” has the right to that water. This “first in time, first in right” principle became the backbone of Colorado water law, differentiating it from riparian water rights found in many eastern states.

The allocation of water rights is governed by a priority system, which creates a hierarchy of water users. Your place in line can greatly affect your ability to extract and use water. This system was formalized as the population grew and the demand for water resources increased. Over time, various committees and legal bodies have provided rulings that further define and refine the application of water laws to ensure fairness and efficiency in water distribution.

Influence of Historical Events on Current Laws

Historical events have had a profound impact on the water laws that currently shape your ability to collect rainwater in Colorado. For example, extended periods of drought and the need for agricultural development in the arid West led to the enforcement of strict water rights to manage scarce resources. The evolution of water rights and the state’s approach to water allocation stem from such events, continuously influencing the legal landscape of water use.

Legal challenges and environmental considerations have spurred further revisions to these laws, reflecting the need to balance individual rights with ecological sustainability. It’s these historical precedents and ongoing legal adjustments that form your current understanding of water law in Colorado.
