HB 24-1362

House Bill 24-1362, which has been signed into law and will take effect on January 1, 2026, aims to encourage the use of graywater across Colorado by allowing new construction projects to install systems that treat and reuse this type of wastewater. Graywater is water from sources like sinks and washing machines that can be reused for purposes such as watering plants or flushing toilets. While local governments still have the authority to ban or restrict the installation and use of these systems within their jurisdictions, they must inform state authorities about any regulations they put in place regarding graywater usage. This bill affects homeowners, builders, and municipalities by providing guidelines and incentives for more sustainable water practices.
