Full Breakdown

Texas Water Code Section 11.012 explicitly permits rainwater harvesting, and Texas law prohibits HOAs and municipalities from banning residential rain collection systems. Conroe has no local ordinance restricting rain barrels or cisterns. Given Conroe's mandatory irrigation restrictions from May through October, rainwater harvesting provides a way to supplement landscape watering on non-watering days. Large cistern installations may require building permits if they involve plumbing connections. The city's Drought Contingency Plan (Ch. 70, Art. VIII) encourages water conservation methods.
