Despite common misconceptions, rainwater collection is fully legal and encouraged in Texas. The state has laws protecting homeowners' rights to harvest rainwater, and even offers tax exemptions and rebates to incentivize the practice. Rainwater can be used for outdoor needs like watering lawns and washing cars, and with proper plumbing, can also be used indoors.

Why it matters

Water conservation is crucial in Texas due to frequent droughts and growing populations. By allowing and incentivizing rainwater harvesting, the state aims to reduce demand on municipal water systems and preserve groundwater resources, while also lowering utility bills for homeowners.

The details

Across Texas, residents can legally collect rainwater from their rooftops using rain barrels or storage tanks. State law prohibits homeowners' associations from banning rainwater harvesting systems, though they can impose reasonable restrictions. Texas also offers financial incentives like sales tax exemptions on collection equipment and property tax benefits for water conservation improvements. Rainwater can be used for outdoor needs like landscaping and washing cars without any special permits, but using it indoors requires installation by a licensed plumber, proper backflow prevention, and notification to the local water provider.

  • Texas passed laws protecting the right to collect rainwater in the early 2000s.
  • Financial incentives for rainwater harvesting have been in place in Texas since 2013.
