A Rosie On The House Replay This episode explores practical, low-cost strategies for reusing household gray water to irrigate landscapes. Brad Lancaster shares decades of experience designing regenerative water systems in dryland environments, emphasizing simple gravity-fed solutions over complex infrastructure. The conversation highlights how homeowners can dramatically reduce water use by “stacking functions” and capturing water already on-site. By pairing gray water with rainwater harvesting, households can meet most or all of their irrigation needs.
