Rainwater harvesting is legal and encouraged across arid El Paso County. The county sets no restrictions, and Texas Property Code Section 202.007 bars a homeowners association from prohibiting rain barrels or a rainwater harvesting system.
Texas strongly favors rainwater harvesting, and El Paso County imposes no ordinance limiting it. On a desert parcel, collecting rooftop runoff in barrels or cisterns for outdoor irrigation is fully allowed, and small residential systems generally need no permit. Texas Property Code Section 202.007 makes any deed restriction void if it prohibits or restricts an owner from installing rain barrels or a rainwater harvesting system, though an HOA may impose limited aesthetic conditions such as street screening. Tax Code Section 151.355 exempts harvesting equipment from sales tax. A system connected to a building's potable plumbing must meet Texas plumbing standards, but a standalone irrigation barrel does not. Given low rainfall, captured water is a valued supplement.
There is no county penalty for harvesting rainwater. An HOA that flatly bans rain barrels acts contrary to Property Code Section 202.007. Systems plumbed into potable water without meeting state standards can be a plumbing-code issue.
