Is rainwater harvesting legal in Texas?

Rainwater harvesting is both legal and encouraged in the state of Texas. 
Multiple laws support the collection of rainwater by both private and public entities. For example, Texas Property Code prevents homeowners associations in the state from prohibiting rainwater harvesting systems for personal use. Additionally, Texas requires new state facilities to add rainwater harvesting systems in their designs, according to the Texas Water Development Board.

Rain Barrel

    Here are some tips for rainwater harvesting, according to AgriLife Today:

•    “Make rain barrels out of food-grade barrels to help keep harvested water clean.
•    Avoid containers that once held petroleum or soap.
•    Modify an existing downspout to divert water into your rain barrel.
•    For a roof with no gutters, position your barrel under the valley of the roof, where two sloped planes meet.
•    Use a decorative “rain chain” to get water into your barrel.
•    Try harvested rainwater for any non-potable application.
•    Consider a moisture meter to test watering efficiency in the landscape.
•    Read the Texas A&M AgriLife Water University rainwater harvesting guide.”
