JKB Housing did an excellent work in implementing our Rain Water Harvesting System in our House. They are specialist to understand existing house structure and plan the Rain Water Harvesting system accordingly. They do this as a service to the environment, so they won’t cost you the labour charges for this implementation. Yes its free on Labour cost and only the materials for this system costed us. The implementation was also very quick and clear. I would strongly recommend them to implement the Rain Water Harvesting System.
