In-Home Use in Texas

As of September 1 of this year, it is now legal for Texas residents connected to municipal water to use rainwater for indoor potable purposes. Prior to the 1st, residents with a city-water connection could use rainwater for anything except drinking. With rainwater harvesting gaining popularity in all parts of the state and water supplies decreasing, politicians were pressured into updating the law in HB 3372. The main delay in this new law and emphasis made is the prevention of backflow from a rainwater system into a city water systems. Municipalities are concerned that poorly maintained RWH systems could leak contaminated water into city mains. With HB 3372, backflow prevention devices are required to address this concern.
