Full Breakdown
Rainwater harvesting is broadly supported in Texas and in Richardson. The North Texas Municipal Water District, which supplies Richardson's treated water, promotes rainwater capture as part of regional conservation programs, and the City offers periodic rebates or free rain barrels through sustainability events. Installation of rain barrels (typically under 50 gallons) on downspouts is permitted without a city permit. Larger cisterns connected to the potable plumbing system require a backflow prevention device and a licensed plumber to comply with Texas Commission on Environmental Quality rules and the state plumbing code. Texas Property Code Section 202.007 limits HOAs: they cannot prohibit rainwater-harvesting systems, though they may require the system to be out of street view, color-matched, and not cause drainage problems. Harvested rainwater may be used for irrigation, toilet flushing (with treatment), and non-potable uses; indoor potable use requires TCEQ-compliant treatment.
