Full Breakdown
Rainwater harvesting in Dallas is generally permitted for residential use including garden irrigation, lawn watering, and non-potable household purposes. Texas does not impose significant state-level restrictions on residential collection.

HOAs may have restrictions on visible rain barrel placement. Potable use of collected rainwater requires treatment systems that meet health department standards. Some cities offer rain barrel rebate programs.
