Rainwater harvesting isn’t just a fancy term; in many cities it’s becoming essential as water tables drop and tanker dependency grows. If a building has proper gutters and pipes that channel roof rain into storage or recharge pits, it shows planning beyond just “pass the water somewhere.”
Asking, “Yahan rainwater harvesting proper hai kya?” tells you if the society is thinking long-term about water. In some areas, such systems also mean fewer issues with flooding around the building because water is guided sensibly.
It gives a sense that you’re buying into a place where resources are respected, not wasted.
