Colorado Rainwater Harvesting
State Rainwater Harvesting Laws and Programs
Droughts, water supply worries and population changes serve as catalysts for states to consider legislation related to water conservation and alternative sources of water including rainwater harvesting. State legislatures have considered bills to allow, define and clarify when, where and how rainwater harvesting may occur. Rainwater harvesting is commonly defined as the act of utilizing a system to collect and use rainwater for outdoor uses, plumbing, and, in some cases, consumption. Rainwater collection or rainwater catchment are other terms used to refer to this practice.
State legislatures consider factors, such as water rights, quality standards and public health, that rainwater harvesting may impact. In some states, especially in the West, water laws stated that all precipitation belonged to existing water-rights owners, and that rain needs to flow to join its rightful water drainage. Legislators also must ensure water quality standards and public health concerns are met when considering rainwater harvesting legislation. For example, collected rainwater may be used for non-potable purposes (e.g., watering indoor or outdoor plants) but may be restricted for potable purposes (e.g., drinking water).
Texas and Ohio have devoted considerable attention to this issue and have enacted several laws regulating rainwater harvesting. (See list below for some examples.) Texas and Ohio allow rainwater harvesting for potable purposes, a practice that is frequently excluded from other states’ laws and regulations. Rhode Island, Texas and Virginia offer tax credits or exemptions on the purchase of rainwater harvesting equipment. Oklahoma passed the Water for 2060 Act in 2012 to promote pilot projects for rainwater and graywater use among other water conservation approaches.
Water in Colorado must be allotted according to the prior appropriation system. This is a common system in the West and is often referred to as “first in time, first in right”. Under the doctrine of prior appropriation, individuals have the right to put water to a beneficial use based on priority of the user. Non-priority use of a water source may carry penalties.
The collection of rainwater for beneficial use was recognized as a potential injury to senior water rights and was historically prohibited in Colorado. However, a 2007 study conducted by the Colorado Water Conservation Board (CWCB), nearby districts and Douglas County determined that only three percent of rain actually reached a stream or the groundwater. Colorado followed up by enacting two pieces of legislation in 2009 – one allowing certain types of well owners to use rainwater (Senate Bill 80) and one authorizing pilot development projects (House Bill 1129). With House Bill 1129 (enacted in 2009), the legislature directed the CWCB to establish criteria and guidelines for the authorized pilot projects. The CWCB developed and approved these criteria and guidelines in January 2010. Further updates were directed by House Bill 1016 in 2015 and were approved in January 2016.
Under a new Colorado law, House Bill 1005 (2016), residential homeowners are now able to use two rain barrels, with a combined capacity of 110 gallons, to capture precipitation from their rooftops. The collected precipitation is required to be used on the property where it is collected and may only be applied to outdoor purposes such as lawn irrigation and gardening. The law guarantees collection of precipitation from rain barrels does not interfere with existing water rights and that the use of a rain barrel does not constitute a water right. The state engineer is required to track adoption and usage among homeowners.

A landscape contractor working within the classification of his or her license would be authorized enter into a prime contract for the construction of a rainwater capture system if the system is used exclusively for landscape irrigation.
In 2009, two laws were passed that loosened restrictions. Senate Bill 80 (2009) allowed residential property owners who rely on certain types of wells to collect and use rainwater (Colo. Rev. Stat. §37-90-105). House Bill 1129 (2009) authorized ten pilot projects where captured precipitation was used in new real estate developments for non-potable uses (Colo. Rev. Stat. §37-60-115).House Bill 1016 (2015) updates criteria and guidelines for rainwater harvesting pilot projects with the goal of incentivizing applicants, and applies lessons learned from previous pilot projects.House Bill 1016 (2015) updates criteria and guidelines for rainwater harvesting pilot projects with the goal of incentivizing applicants, and applies lessons learned from previous pilot projects.
House Bill 16-1005 (2016) allows residential homeowners to use two rain barrels, with a combined capacity of 110 gallons, to capture preciptation from their rooftops.

Rules regarding the installation and maintenance of rainwater harvesting systems that are used for indoor potable purposes and connected to a public water supply system are required to be developed, prior to this bill it could only be used for non-potable purposes. The rules must include criteria to ensure that safe drinking water standards are met and the water does not come in contact with the public water supply at a location off of the property.
A person who intends to connect a rainwater harvesting system to a public water supply system for potable purposes is required to give written notice to the municipality or the owner or operator of the public water supply system. A municipality or public water supply system may not be held liable for any adverse health effects allegedly caused by the consumption of water collected by a rainwater harvesting system that is connected to a public water supply system and is used for potable purposes if the municipality or the public water supply system is in compliance with the sanitary standards for drinking water.
Each municipality and county is encouraged to promote rainwater harvesting at residential, commercial, and industrial facilities through incentives such as the provision at a discount of rain barrels or rebates for water storage facilities. The Texas Water Development Board (TWDB) is required to ensure that training on rainwater harvesting is available for the members of the permitting staffs of municipalities and counties at least quarterly. School districts are strongly encouraged to implement rainwater harvesting systems.
A municipality or county is prohibited from denying a building permit solely because the facility will implement rainwater harvesting.
Utah allows for the direct capture and storage of rainwater on land owned or leased by the person responsible for the collection. According to Senate Bill 32 (2010), a person registered with the Division of Water Resources may collect and store no more than 2,500 gallons of rainwater. If unregistered, no more than two containers may be used, and the maximum storage capacity of any one container shall not be greater than 100 gallons (Utah Code Ann. §73-3-1.5).
