Rainwater Collection laws in Oregon

Oregon law generally allows for the collection and use of rainwater. The regulations differentiate between small-scale collection for non-potable uses and larger, more complex systems that may involve connection to plumbing or use for drinking water. For non-potable outdoor uses, the process is relatively straightforward. However, systems intended for indoor use or potable water may require adherence to specific building codes, health department standards, and plumbing regulations. The regulatory framework aims to ensure public health and safety, especially concerning water quality and the prevention of cross-contamination with public water supplies. While property owners generally have the right to collect rainwater that falls on their property, the practical implementation might involve considerations related to the size of the collection system, its intended use, and its integration with existing water infrastructure. For larger projects or those involving potable water, consulting with relevant state and local agencies is advisable to ensure compliance.
