In Texas, it is not illegal to collect rainwater and save it for future use. In fact, the practice is encouraged by the Texas Water Development Board as it decreases the demand for public water. Residents may even be able to claim an exemption on supplies, labor, and equipment for rainwater collection from state-applied sales tax.

While some states restrict the use of saved rainwater for human consumption due to concerns about bacteria and storage issues, Texas does not have such restrictions. Residents in East Texas, Dallas, and other parts of the state receive a significant amount of rainfall, making rainwater collection a practical and environmentally friendly option.

If considering collecting rainwater in Texas, it is recommended to contact your county government and local water providers for advice and expertise. The practice of rainwater collection is not only legal in Texas but also beneficial for conserving water resources and reducing reliance on public water supplies.
