College Station, TX Landscaping Rules: Rainwater Harvesting (2026)

Nothing in Texas state law meaningfully restricts a College Station homeowner from collecting rainwater for garden irrigation, lawn watering, or other non potable household purposes. The stronger shield is aimed at homeowners associations. Texas Property Code Sec. 007 says an association may not include or enforce a dedicatory instrument provision that prohibits or restricts installing rain barrels or a rainwater harvesting system, and subsection (b) declares any provision that tries void. Because the statute bars enforcement as well as adoption, an old deed restriction already on the books is just as dead as a new one.

The protected list runs wider than barrels. The same section shields measures promoting solid waste composting of vegetation, including grass clippings, leaves, or brush, and leaving grass clippings uncollected on the lawn; efficient irrigation systems, including underground drip systems; and drought resistant landscaping or water conserving natural turf. A homeowner pairing a rain barrel with drip lines and drought tolerant beds is covered on every front. Practical limits remain. Rain barrels and cisterns can be installed without special permits in most cases, but a large system may trigger building or plumbing permits, so scale matters before you build.

HOA guidelines can still address where visible barrels are placed. And collected rainwater is not drinking water by default: potable use requires a treatment system that meets health department standards.
