Turn your roof into a water collection source with rainwater harvesting. Texas has one of the most comprehensive laws protecting rainwater harvesting, the Texas House Bill 3391. In 2001, Texas excluded components of rainwater harvesting systems from sales tax, Section 151.355 of the Texas Tax Code.
To claim this exemption, the purchaser must furnish a Tax Exemption Application Form 01‐339 to the supplier at the time of purchase. Link to the Sales Tax Exemption Form for Texas:
Harvesting rainwater for later use in irrigation, as a drinking water source or replacing your other water needs:
– Saves money on water purchasing through a utility or other water source
– Reduces demand on the municipal water supply
– Reduces flooding, erosion, and contamination of surface water with contaminants
– Provides a clean, pH balanced water source that is free of salts and other minerals that can harm plant root growth.
Rainwater harvesting can be used both in large-scale landscapes, such as parks, schools, commercial sites, parking lots and apartment complexes, and for personal home use. ARCSA, the American Rainwater Catchment Systems Association, is a nationally recognized accredited professional organization that can certify that the company that you work with will design and install a system up to standard.
